IZ Planet 5 wiring diagram: common problems

In IZH Planet motorcycles, be it version 3, 4 or 5, the ignition installation in accordance with the diagram must be carried out using the device that came with the motorcycle. But since it is not so easy to find this device today, we will make do with improvised means. Non-contact ignition is configured by adjusting and setting the gap of the distributor contacts. An equally important nuance is the correct setting of the moment of sparking.

Diagram and designation of parts of the IZH distributor

If your IZH Planet 3 is equipped with a single-cylinder internal combustion engine with a G-36 M generator device, then in this case the procedure for setting the gap is carried out by turning the eccentric, marked in the diagram with the number 1. In this case, bolt 2 according to the diagram must be loosened, and the eccentric itself is turned or right or left. Before setting the BSZ on products from the IZHMASH plant, the crankshaft must be turned. It rotates until the moment of greatest divergence of contacts occurs. It is in this position that the ignition of the IZH Planet 5 is adjusted - you need to ensure that the maximum gap on the contacts is around 0.35-0.45 mm.

According to experts, the ignition system should be adjusted with the cylinder head removed. In this case, the piston itself must be located in a position where it does not reach the dead center; to find out what the clearance should be in this case, you need to use the instruction book. For example, in versions 3 this parameter should be 3.5-4 mm, in Planets 4 - from 3 to 3.5 mm, and in Sports versions - from 3.5 to 3.8 mm. It is in this position that the spark will appear. The adjustment procedure in this case is performed by turning the interrupter assembly, while the bolts marked in the diagram as number 10 must be loosened.

Assembly diagram for IL

Adjusting the ignition, in particular, setting the gaps between the contacts of the interrupter device, should be performed in the following order:

First of all, the crankshaft is turned by the kick starter.
One of the interrupting elements is set to the contact opening position. In this case, the bolt marked number 4 in the diagram must be loosened.
Next, using the eccentric number 3, the gap is set; this figure should be from 0.4 to 0.6 mm. After this, the same actions are carried out with the second pair of contacts.

It should be noted that the entire procedure must be carried out with the candles unscrewed. When you place the dipstick in the corresponding hole for the spark plug in the right cylinder, you need to turn the crankshaft with the kick starter. You need to find the top dead center and having found it, you should make several marks on the dipstick - one of the marks should be placed at the level of the hole, and the other should be located slightly higher - about 2-3 mm. After this, the crankshaft must continue to be turned, this is done until the upper mark reaches the position in which the first mark at top dead center was set (video author - Garage in the USSR).

In this position, the elements of the interrupter assembly, which is located on the lower surface, will begin to open. It should be noted that the procedure for setting the contact opening is done by turning the base, but to do this you need to loosen the bolts numbered 2 and 7. And when you can make the adjustment correctly, these screws will need to be tightened. As for directly determining the moment of rupture, it can be detected thanks to a light bulb, which must be connected in advance to the body ground and the distributor terminal.

After the torque on the right cylinder has been set, the same procedure is performed in a similar way only on the left cylinder. In general, the situation is similar, only in this case it is not the lower, but the upper base that rotates, and in this case, bolts 1 and 7 should be loosened.

Design and reliability

IZH Planet 2, as evidenced by the number in the model name, became the second motorcycle in the Izhevsk Planet series.
It differs from the “ancestor” of the family in greater comfort and power of the power unit, as well as an updated, more modern (for that period of time) design.

Thus, Planet 2 received a signature paint job, a muffler and wheel rims covered with decorative chrome, a polished crankcase cover, as well as brake covers and a carburetor casing with a layer of hammer enamel.

The motorcycle seat has become wider and more comfortable. Its finishing is made of colored textinite.

The second generation model is designed in such a way that its repair does not require special or specific tools, conditions or equipment.

The mechanics are quite simple and straightforward, and spare parts are produced in abundance.

IZh Planet 2 owes its excellent cross-country characteristics to good traction at low speeds, high suspension and competent gearbox design.

Among other things, the owners of the bike unanimously declare the highest reliability of the engine and its amazing durability. This is confirmed by the manufacturer, who provided a warranty for a mileage of 15 thousand kilometers or a year and a half of operation.

Izh Jupiter 5 ignition switch connection diagram

We mark the Hall sensor mount in such a way that the distance to the rear wall of the sensor through the magnet slot from the center of the armature is around mm. What advantages open up to users who decide to install electronic ignition on the Izh Jupiter are described below. Get a nightmare! Thanks to the modulator plate, smooth ignition operation is ensured.

What kind of precise engine operation can we talk about here? An ignition adjustment is necessary if the engine is running poorly, the muffler or carburetor is firing. As soon as the voltage is on the pin. A caliper will be needed as a depth gauge. The most common of them are listed below: Ignition gaps change their original position while driving a few days after adjustment; A spark occurs every once in a while, since the contacts regularly burn out; Capacitors are constantly damaged; Low spark power; If you add two or three volts to the battery, it is quite difficult to start it. If the engine is 1-cylinder, then the cutout angle in the modulator should be approximately degrees, but if the engine is 2-cylinder, then the cutout angles should be 60 degrees.

Its thickness is 0.45 mm. We connect the second wire from the switch to terminal “1” of the ignition switch; the second wire from the same terminal goes to the signal. Tighten the screws well.

Replacing the head light Riding Jupiter 5 at night is the lot of the most daring and experienced bikers. Thus, the coils are supplied with 12 volt voltage from the battery (diagram 1). The ignition timing must match on any cylinder used. If your spark appears earlier or later, then perform the following steps. We determine the moment of spark by the spark itself.

Connect it to the second and third contacts of the DC. After turning on this key position, power is supplied from the battery to the primary circuit according to a simplified scheme. Now you can use BSZ. Then loosen the screw and turn the eccentric. As a result, a charge of less than 12 V appears on the spark plug, which poorly ignites the combustible mixture in the cylinders.

A discharge is applied to the spark plug, which causes the mixture to ignite, causing the crankshaft to start moving. Using the generator bolt, turn the crankshaft clockwise. It is necessary to ensure that the breaker contacts open to the maximum distance. The characteristic knocking sounds of iron components in the crankcase and accompanying detonations also disappeared. WIRING TO IZH (PLANET 5)

Required Parts

In order for the ignition system to work correctly, a number of auxiliary parts are required. They are listed below:

Switch for BSZ VAZ cars. You should not choose exclusively from the low price segment. The Astro switch has a lot of positive reviews;
Hall Sensor. The best option for Jupiter 5 is a similar manufacturer VAZ. By purchasing it in branded packaging, you protect yourself from counterfeits;
Ignition coil with two terminals. You should choose between the gazelle engine number 406 or Oka with an electronic ignition system;
A pair of silicone armor wires with rubber caps;
The modulator is a butterfly-shaped plate made of iron.

Modulator

The most difficult stage is the production of the modulator. It is important to maintain the required shape. The more accurately the required dimensions are observed, the lower the likelihood of problems occurring after the system is implemented, that is, there will be no need to adjust it with a file. The ignition timing must match on any cylinder used.

The bolt hole must be located in the middle. Otherwise, the engine operation will not be synchronized. It is also recommended to check the integrity of the crankshaft bearings. If you find defects, you should immediately replace it.

The contact ignition is not able to work normally if the bearings are damaged. The thickness of the part should not exceed one and a half millimeters. If it is thin, it will not be possible to avoid deformation, and if it is thick, it will come into contact with the surface of the hall sensor housing.

To create the plate, it is allowed to use any material except steel. Aluminum and others should not be used as they are not magnetic. The drawing that must be followed can be found in the public domain. The presented diagram will be useful to those people who decide to modernize the vehicle ignition device. Below are methods for installing electrical ignition devices in Jupiter.

It must be turned by a professional turner. He will make a simple disk and draw on it the markings of elementary distances between the corners. Then, in accordance with it, you will cut out the necessary sectors at home. The cost of the modulator is seventy rubles.

It is not advisable to use an ordinary plate, since its width is less than twelve millimeters. This will not be enough to fully accumulate the energy resource in the coil. Of course, it can be installed, but achieving four thousand revolutions per minute will become impossible.

In addition to the above you will need:

A stud with an applied thread of seven millimeters, pitch 1, as well as a pair of nuts with washers of the corresponding parameters. The priority material for these components is brass. This is explained by the least magnetization of the plate from the generator rotor. If you use a standard bolt, then difficulties may arise with the introduction of ignition. The bolt tends to follow the modulator as it is tightened. However, it is necessary to observe the leading indicator, maintain the same position of the rotor and modulator, and tighten the bolt. It is advisable to use a pin, since many are not able to perform all the necessary actions in total;
A set of wires with connectors for ignition without contact from VAZ. This part can be purchased or made with your own hands.

Maintenance

The owner can independently perform some maintenance procedures:

check the motorcycle generator if the battery loses charge;
set the gap between the breaker contacts;
adjust the quality of the sound signal.

The need to inspect and adjust the wiring arises if:

the motorcycle moves in the rain for a long time, as this causes oxidation of the contacts;
a motorcyclist rides in an area with a lot of vegetation that damages wiring;
The driver rides in snow in winter, which can stick to electrical wiring parts and damage them.

Self-check of the Planet 5 motorcycle generator in case of loss of charge

The cause of loss of charge in the IZH Planet 5 battery is most often a breakdown of the generator.

To check it yourself you need:

multimeter device;
straight screwdriver.

Step-by-step instruction

The following steps must be followed:

Disconnect the wires from the battery and remove the generator cover.
Disconnect the top 5 wires from the generator, first unscrewing their fastenings. In order not to mix up the wires during assembly, it is worth marking them.
Measure the winding resistance using a multimeter in ohmmeter mode. To do this, you need to touch the body with one probe, and the other should be connected in turn to the 3 wires of the winding. There should be no short circuits, as indicated by the inscription on the multimeter screen.
Test the resistance between the stator contacts: you need to touch them one by one with the multimeter probes. The value on the screen should be 8 ohms.

The presence of a short circuit in the 3rd stage or a discrepancy in the indicators in the 4th will indicate problems with the generator.

How to correctly set the gap between the contacts of the breaker?

In order to set the gap between the breaker contacts, you will need:

straight screwdriver;
wrench 10;
candle key;
probe 0.4 mm thick (+/– 0.05 mm).

Next, you need to follow the steps sequentially:

Place the motorcycle on a stand and place the gearbox in neutral.
Remove the right crankcase cover and unscrew the spark plug.
Using a 10mm wrench, grab the generator rotor mounting bolt and turn the crankshaft to a position where the contacts are as far apart as possible.
Loosen the screw securing the contact.
Place the probe between the contacts and adjust the tightening of the eccentric screw until the probe passes the contacts with little resistance.
Tighten the contact fixing screw.

Troubleshooting the audio signal and improving signal quality

Poor sound signal quality is mainly caused by improper adjustment.

The following tools will be needed for setup:

wrench 7;
a simple screwdriver.

Step-by-step instruction

To adjust, do the following:

Loosen the locknut with a wrench.
Turn on the ignition.
Press the button to turn on the sound signal.
Adjust the sound by rotating the adjusting screw.
When the desired result is achieved, tighten the locknut.

While improving the car, the plant made a number of changes to it. In particular, the fixation and clarity of operation of the IZH P101 and IZH P102 switches and the switch on the steering wheel have been improved. The optical element in the headlight was replaced by the Soviet FG 137, and the IZH UP1 turn signal lights were replaced with standardized lights 16.3726. There are other innovations as well.

Jupiter-4 is now equipped with 12-volt equipment. The plant is also preparing for production a new Planet-Sport model, the electrical equipment of which is unified with Jupiter-4.

However, even now, Planet-Sport owners can use a number of IZH Yu-4 electrical appliances without significant modifications. These include generator 28.3701 (if it is sold without a breaker and capacitor, they can be taken from the old IZH GP1); direction indicator lights 16.3726; headlight optical element FG 137; rear light FP146; speedometer SP102; battery 6MTS-9.

To install the IZH RP2SM-10 turn signal breaker in the headlight housing, you need to make an additional bracket from a steel strip 1-1.5 mm thick and replace the plug tips with round ones. After the same modification of the tips, the combined switches IZH P101-20 and IZH P102-20 from the IZH Yu-4 motorcycle can be used on Planet-Sport. To do this, squeezing out the fixing tendrils with an awl or knitting needle, remove the plug tips. They cut them off and crimp and solder round tips on the stripped ends of the wires. At the IZH P101-20 switch, a blue outlet wire 130-150 mm long with a plug tip is soldered to the black wire.

Improvements in the electrical equipment of motorcycles and the use of new devices have naturally led to some complication of the electrical circuit. Let's get acquainted with its main elements using the example of electrical equipment of the “Planet-Sport” circuit, which is in many ways similar to the circuits of other Izhevsk motorcycles.

Ignition system

. This is perhaps the main system, because without it the motor cannot work. Let's trace and remember its electrical circuit. From the battery 24 through fuse 25 and rectifier 26, power is supplied to terminal (2) of the connecting panel in the headlight housing and then to terminal (3) of the ignition switch 9. When the key is turned to position I, the terminals (3—2—1 and 5) are closed -6). Now from terminal (1) of the lock, the current flows to terminal (5) of the connecting panel, from it to the emergency ignition switch 11, and through its closed contacts to terminal (1) of the connecting panel and then to the primary winding of the ignition coil 21 (the second end of the primary winding — terminal “—” is connected to the breaker). This turns on the motorcycle's ignition circuit.

If the engine does not run due to lack of spark at the spark plug, check whether high voltage is supplied to it. To do this, remove the wire from the cap and bring it to the edge of the cylinder with a gap of 2-3 mm. If, when the crankshaft is rotated by the kick starter, a spark does not appear between the wire and the cylinder, there is no high voltage. The reason for this is found as follows. When you turn on the ignition, use a 12-volt test light to check whether power is supplied to the “+” terminal of the ignition coil. If not, then check the entire circuit, starting from the battery. The usual cause of no voltage is loose or oxidized terminals, or a faulty fuse.

Having ensured that normal voltage appears at the “+” terminal of the ignition coil, carefully clean the breaker contacts, check and set a gap of 0.4-0.6 mm between them and adjust the initial ignition timing.

If the engine produces only isolated flashes when starting, and a white coating appears on the contacts of the breaker, it means that the capacitor has failed (rarely, but it happens).

With the correct gap, clean contacts of the breaker and a working capacitor, the reason for the lack of a spark on the spark plug may be a malfunction of its plastic cap (ground fault) or the ignition coil (it is non-separable, so it must be replaced). A poor-quality spark plug can cause engine interruptions or make it difficult to start. Signaling and lighting system

Direction indicator

. When the ignition is turned on (key in position I), electricity from the battery 24 (or rectifier 26 when the engine is running) is supplied through terminals (3 and 1) of the ignition switch 9 to terminal (5) of the connecting panel. The power wire for turn signal relay 6, horn 18 and the “positive” wire for light switch 11 located on the steering wheel are connected to it. From relay 6, power is supplied to the lights through the terminal (9) of the connecting panel and then to the turn signal switch 19. From it, through terminals (6 and 7) of the connecting panel, it goes to lights 10 and 28 turn indicators. The turn signal indicator lamp 16 is also connected to the terminals (6 and 7) of the connecting panel through the diode block 7.

The reason for the failure of direction indicators to work most often is the lack of “ground” in the lamps when their fastening to the frame is loosened, oxidation or loosening of the connections of the tips with the wires, contacts in the lamp sockets.

To speed up troubleshooting, the circuit is checked from the non-working consumer to the power source. To determine the functionality of the turn signal relay 6 without dismantling it, you must first make sure that voltage is supplied to terminal (5) of the connecting panel and that the brown wire of the relay is securely connected to ground. Then check the serviceability of the circuits going to the direction indicator lights by connecting terminal (5) with terminals (6 and 7) of the connecting panel with a separate wire. The lights on the right (terminal 6) or left side (terminal 7) and indicator lamp 16 should light up without blinking if the circuits are working. Next, disconnect the pink relay wire from terminal (9) and connect it to terminals (6 and 7) on the connection panel. If the relay is working properly, the starboard or port side lights should blink at a frequency of 60 to 120 per minute.

The relay removed from the motorcycle is checked using two A12-21-3 test lamps (each with a power of 25 W), connected in parallel. Connect the “plus” of a constant voltage of 12 volts to the red wire, the “minus” to the brown wire, and the control lamps to the pink wire. When the device is working properly, the lamps should flash at a frequency of 90 ± 30 per minute.

headlight

. It contains the main part of the wiring diagram, the turn signal relay, the neutral 3 and oil pressure indicator lamps 5, the lamp 8 that illuminates the speedometer scale, the parking light lamp 1, the head light lamp 2, the ignition switch 9 and the speedometer.

On the latest motorcycle models, the turn signal switch is mounted on the frame under the gas tank.

Let's consider the electrical circuit of the head, parking and side lights. When the ignition is turned on (key in position I), power is supplied to terminal (4) of the connecting panel, then through the contacts of the light switch 11 - to the central contact of the high-low beam switch 19. Next, through the terminals (11 and 12) of the connecting panel - to the high or low beam filament of lamp 2.

The side light in the headlight (lamp 1) and in the rear lamp 29 lights up when switch 11 is activated and current flows through contacts (5 and 6) of ignition switch 9.

If the ignition key is turned to position II (parking), then these lamps receive power through its contacts (3 and 5) regardless of the position of the switches on the steering wheel.

Lamps that glow dimly when the engine is not running indicate that the battery is not fully charged. If this is observed in all modes of engine operation, it means that the voltage in the lamp power circuit drops significantly. In this case, check the electrical connections of the power and ground wires, clean and tighten the screw and plug connectors, contacts in the headlight and flashlight lamp sockets. Check the serviceability and reliability of the contacts in the switches and fuse.

Since the motorcycle is constantly being improved during the production process and its electrical circuit is changing, it is advisable to include the differences in your motorcycle in the circuit printed here so that, using it, you can always easily and quickly find the desired circuit and determine the malfunction.

V. SAMOILOV, engineer Izhevsk

The wiring diagram of IZH Planet 5 is not complicated, and it is quite possible for a person, even with little experience, to independently check its serviceability and carry out repairs. It is enough to know the principle of operation and its main problems, which owners of the IZH P5 motorcycle often encounter.

Features of electrical equipment

The wiring diagram of IZH Planet 4 is almost completely copied from the Jupiter model that was the first to appear on the factory assembly line.

The only differences are that:

The Planet family has one working cylinder, and accordingly the ignition system is designed to ensure its operation;
The IZ Jupiter family, unlike the Planet, has 2 working cylinders; accordingly, the wiring diagram has additional repeating elements.

Headlight

IZH Planet 4 is equipped with more advanced lighting devices:

Headlight type "European beam" FG137V with glass with an asymmetrical pattern;
Low beam mode with lamp A12-45 + 40 W;
Modern direction indicators type 16.3726 (lamp power - 25 W).

Photo of IZH Planet 4 model 1986

Thanks to the modernization of the lighting system, as well as the configuration of the motorcycle:

battery 6MTS-9;
high power alternating current generator 100 W,

The illumination of the road in the flow of traffic has significantly improved, and traffic on public roads has become safer. At the same time, the price of the motorcycle did not change significantly, which brought its sales to a new level of popularity.

Contactless ignition system

The motorcycle used a new contactless ignition system, the operating principle of which was based on the following operating algorithm:

The generator rotor generates pulses when rotating;
The storage capacitor is charged through diodes (in the diagram below indicated as VI, V5), as well as through a limiting resistor (R1);
Passing through the diode (V6), the electrical signal from the sensor winding (3) enters the thyristor (V4);
After it opens, the charged capacitor (C1) transfers the accumulated charge to the ignition coil (primary winding - 4);
Under its influence, a high voltage pulse is induced in the secondary winding;
Through the high-voltage wire, the central electrode of the spark plug receives a charge;
A spark between the electrodes ignites the air-fuel mixture in the motorcycle engine cylinder.

The factory instructions contain the original diagram of the contactless ignition system

The electrical wiring of the IZH Planet 4 motorcycle, due to the peculiarity of the contactless ignition system, has differences in the layout of the main components:

The electronic unit of the stabilizer and ignition system is placed in a single housing;
It is equipped with two plug connectors;
In order to increase reliability, the block is filled with polyurethane foam (non-separable version);
Its operating parameters are designed to provide a light signal circuit voltage in the range of 11.5 – 14.5 V.

In addition, the use of a 12-volt circuit led to the division of the ignition system into three electrical circuits that differ in voltage levels:

A high-voltage circuit consisting of an ignition coil, a spark plug, a spark plug tip and a high-voltage wire;
Storage capacitor charging circuit, consisting of a charging winding, connecting wires with plug connectors, BCS and the primary winding of the ignition coil;
The sensor circuit, consisting of its winding, connecting wires and plug connectors.

Generator IZH Planet 4

A more advanced generator began to be installed on the new model of the Izhevsk Motor Plant, capable of serving the increased needs of the electrical equipment system, in contrast to the wiring diagram of the IZH Planet 3.

Original factory circuit diagram of the IZH Planet 4 motorcycle generator

Among the design features it is worth highlighting:

Eight coils placed in the stator slots;
Serial connection diagram;
Coating of coil windings with insulating varnish;
Original fastening to the stator, made using washers and bent petals.

To identify faults with your own hands, you need an ohmmeter or a universal tester, which can be used to measure the resistance of the windings:

If the values of the measured resistances differ significantly, it is necessary to inspect the generator stator to detect broken winding leads;
The reason for unstable operation may also be their short circuit. If possible, identified faults are eliminated by soldering.

Motorcycle Features

According to industry norm, the motorcycle had an alphanumeric index:

IZH 7.107-010 – basic model;
IZH 7.107-020 was already equipped with a new lubrication system and improved front axle suspension. In addition, the wiring diagram of the IZH Planet 5 motorcycle had a contactless ignition system, independent of the battery;
IZH 7.107-030 was equipped with a spring-hydraulic shock absorber and a redesigned rear wheel brake drive;
IZH 7.107-040 was produced with modified kinematics and a modified front wheel brake. The wiring diagram on IZH Planet 5 remained contactless until 2008.

In addition, a side trailer (sidecar) or a universal cargo platform (without a seat) could be attached to the motorcycle.

Description of the symbols for the terminals on the rectifier-regulator block BPV 14-10:

–x1 — “minus” of the generator excitation winding;
–x2 — “minus” of the battery (“ground”);
x2 - “positive” wire to the control lamp of the instrument panel;
x3 - “positive” wire to the panel indicator;
x4, x5, x7 - phases of the stator winding;
x8 - “plus” of the battery.

How to check the charging of the Izh Planet generator

First you need to check whether the generator windings are shorted to ground. To do this, take a 12 volt lamp, solder 2 wires (probe) to it, turn off the BPV, turn on the ignition, connect one wire of the lamp to the wire that connects to terminal X8 (BPV), this will be the “+” of the battery (AK). We connect the second wire one by one to wires X5, X4, X7, X1 - the lamp should NOT light up. If the lamp lights up, even not at full strength, it means that the windings are shorted to ground - these could be the wires that go to the generator or a short in the generator itself. X5, X4, X7 - stator windings, X1 - excitation winding.

(if the excitation winding is short to ground, quite unpleasant consequences are possible! such as melting of the brushes, blown AK fuse, if you have one of course :), if not, then the wiring will burn.)

We check the serviceability of the generator operation indicator lamp. To do this, we short-circuit X8, X3 (BPV is turned off, the ignition is on), the control lamp should light up, if not, check the lamp and the wires suitable to it. Now we check the excitation winding, for this we connect one wire of our probe to ground, and the second to X1 (the BPV is turned off, the ignition is on), the probe should light up, if it does not light up, the excitation winding is faulty. (this could be a stuck brush, a break in the wire leading to the brush, or a break in the field winding).br/> If all our tests give a positive result, we check the operation of the generator. To do this, we close wires X1-X2 (the BPV is off), turn on the ignition, start the motorcycle, connect the probe with one wire to ground, and alternately connect the second wire to wires X5, X4, X7, the probe should light up. If the lamp does not light on any wire, it means that the stator winding or the wire suitable for it is faulty. If everything is OK, then the generator is working.

After you have made sure that the generator is working, but there is no charging on the AC or the indicator lamp does not go out when the engine is running, it means that the BPV is faulty.

Cafe Racer

The style largely repeats the previous one, because it consists of giving the motorcycle an appearance similar to the British models of the 60-70s. A distinctive feature of such motorcycles is the special shape of the seat and tail. For our modification model, we will have to work on the rear part and replace the tank with a more streamlined one. You will also have to change a number of details in general, these are:

round mirrors;
one round device instead of a panel;
monochrome, dim color of the main elements;
no stickers;
an abundance of chrome parts (switch feet, turn signals, possibly fenders).

Improved ride quality

The icing on the cake, and in our case the final touch of tuning, is the improvement in driving performance. Some of the tuners approached this issue earlier when they sawed the frame of their motorcycle or raised the tail of a future crossover. For the rest, first of all, you should get rid of your original tires. Among its advantages, only wear resistance can be noted, for which you pay with your safety. It is both universal and useless. The lugs are practically useless; if they get into a mess, under normal conditions on the highway it is noisy, but relatively holds the road, turning into a killer on a wet highway.

Therefore, without hesitation, we throw it away and purchase road, cross or all-purpose tires, based on your requirements. The second point is the suspension. If everything is generally clear with the rear shock absorbers, they are extremely reliable and, in addition, have stiffness settings, then the front fork does not leak only for those who have chosen a different brand. There are two ways to get out of this situation. The first is to add thicker oil. The second is to carry out a complete overhaul of the feathers and replace all parts. Both options do not last long, so the most demanding owners simply change the fork to an imported one, while the rest endure all the shortcomings of their iron horse.

What is the value of this model

Such increased attention to the IZH Planet 2 model is caused by the fact that:

in total, just over 246 thousand were produced;
and there are few surviving copies left;
which only increases its value among collectors.

According to Izhmash, only 246 thousand Planet 2 models were produced throughout the USSR.
Therefore, it was a great success to find preserved motorcycles in garages and sheds of villages and towns (as in the photo below). Moreover, if the previously discussed price has not changed, and the owners give you a bag of spare parts in addition, consider that you have hit the “jackpot”.

Fortunately, you can still find “live” IL with original parts. True, only in this state

Recovery process

When the euphoria of the purchase wears off, a lot of questions arise regarding its repair and restoration with your own hands.

The main task of the new owners:

Restore the electrical system - and there are no particular problems with this, since the electrical wiring of IZ Jupiter 2 and Planet of the second and third generations is identical and interchangeable;
Starting the engine is a more difficult task due to the need to overhaul the power unit and the availability of spare parts;
Return the motorcycle to its original appearance. It is also quite complex and, perhaps, the most painstaking work of the entire project.

The video below shows the restored models.

Factory layout for several generations of motorcycles

Whether to switch to contactless ignition or change the voltage from 6 to 12V is up to you to decide.
If you have such a desire, and you manage to get your hands on a native Izhevsk generator 281.3701, then the replacement process will be much easier.

central locking

Let's consider the process of restoring the central lock, since in most surviving models it is faulty.

Appearance of the headlights and controls of IZH Planet 2

The difficulty is that finding the original lock is very difficult, almost impossible. Moreover, at 6V, since later the Izhevsk Motor Plant transferred all subsequent models to 12-volt equipment.

This is what the filling of the original 6V ignition switch looks like

Therefore, many motorcycle owners adapt parts from later versions of Planets and Jupiters.

The difficulty of installation in this case is as follows:

Uncertainty about whether the lock will work;
How to properly connect wires.

Headlight

Many owners do not attach importance to adjusting the head light, believing that a working light bulb and intact glass are enough for “driving” during daylight hours.

Using this scheme it will be easy to connect all consumers

In fact, this is not so, and adjusting the light is not only desirable, but also mandatory, especially since it can be easily done independently, spending no more than half an hour of personal time on it.

Scheme for adjusting the angle of luminous flux

If you manage to bring IZH Planet 2 back to life, while maintaining its identity and originality, then our information with color diagrams and photos on electrical equipment is not in vain. We hope that it will provide you with all possible assistance, and there will be one more carefully restored domestic legend on the roads.

If something is wrong.

Disconnect the relay regulator (remove the connector). Let's take a tester.
We set the tester to measure resistance. We check the resistance between ground (engine) and the generator wires (three wires, usually yellow). It shouldn't exist. If at least one has it, your motorcycle's alternator has burned out.
We check the resistance between the generator wires, the resistance should be the same, about 1 - 3 ohms. If it is more or not the same, your motorcycle's alternator has burned out.
We set the tester to measure alternating voltage. We start the motorcycle, measure the voltage between the generator wires, it should be more than 18 volts at idle, and more than 40 volts at 3000 - 4000 rpm. If there is no or different voltage, your motorcycle's alternator has burned out.
If the check in points 2, 3 and 4 went well, most likely your motorcycle has a faulty Relay - Regulator or, which also happens, a wiring fault (clean all terminals, check the integrity of the wires, connections to ground). If your motorcycle's generator burns out, this is the place for you: Rewinding the generator with your own hands.

Our service will help you check the charging of your motorcycle.

Check the integrity of wires and connections.

They will eliminate all problems associated with charging the motorcycle.

If the motorcycle is not sufficiently charged, the following may fail: battery, relay - regulator, generator.

Differences from the second Planet

For many modern citizens, the information that domestic motorcycle manufacturers worked tirelessly to improve their models in an era of total shortages may come as a surprise.

Note! The fact takes place, moreover, it is supported by official documents, in particular 1970N04P16-17 - this is the outgoing number of the factory newsletter, which described the changes made. In the photo - official materials of the Izhmash Design Bureau

The new generation motorcycle received:

Direction indicator lights are a first in domestic practice;
Semiconductor relay for controlling direction indicators (installed in the headlight);
New size of wheels and tires (3.50x18 versus previous - 3.25x19);
New brand increased capacity battery (old one on IZH Planet 2 - ZMT-6);
And, of course, more engine power. The power unit now developed 18 hp.

Modifications

But the creator engineers did not stop there and, having released the five-millionth car from the production line, presented a modification of the IZH Planet 3-01.

Mirror and safety arches are the distinctive features of the new modification

Among the innovations it should be noted:

Rear passenger footrests;
Roll bars;
Rearview mirror;
New steering wheel design.

Wiring diagram Izh planet - 5, how to determine the malfunction

07.04.2017

While easily fixing mechanical failures, motorcyclists experience difficulties if the electrics fail. It’s completely in vain, the wiring diagram of the planet Izh 5 is not complicated, it’s easy to figure out.

There is no need to have special stands and equipment for repairs. A minimum knowledge of electrical engineering and a simple avometer (tester) is enough; even often you can get by with just a test lamp.

We will tell you in more detail about the main electrical wiring components and possible malfunctions. Finding a broken wire or damaged insulation is easy (for example, a bad contact always gets hot).

In this case, we look to see if there is a spark at the coil output and at the output at the spark plug contact. Now in detail about the main wiring components of the Izh Planet.

Generator

The heart is the generator (sometimes called a magneto, but they were never used on Izh Planet). Three windings produce alternating current. For excitation, an additional coil is used instead of a permanent magnet. Therefore, it is impossible to jump start a motorcycle with a completely dead or missing battery.

Possible breakdowns in this unit:

Breakdown or breakage of coils. It is checked by measuring their resistance of current-carrying conductors and insulation. If the generator is damaged, it will become noticeably hot.

Failure of the diode bridge - the output voltage will differ significantly from the nominal level or be absent.

Failure of the voltage regulator. Although the electrical circuit includes short circuit protection, it happens that the automation does not work and most often the output transistor burns out.

Battery

The battery in the motorcycle is low-power. The motorcycle does not have a starter, so its task is only to supply voltage to the ignition system and the generator excitation winding during starting. Thanks to the battery, designed for 12 volts, a stable start of the fifth Planet is ensured; up to the third model, the wiring was 6 volt, and the ignition was not always clear.

Possible battery malfunctions:

Mechanical damage - housing, plates, leakage of electrolyte.

Loss of electrolyte density is determined by measurements using a hydrometer.

The short circuit of the plates in the banks is detected by measuring the resistance.

It is possible that the connection is not correct, minus not on the body (frame) of the motorcycle - all the electronics will not work.

Ignition system

The ignition chopper is used to ignite a spark at a certain point in the piston stroke. In early modifications of the electrical wiring of Izh Planet 5, contact was mounted, later electronic.

The main malfunctions of this unit:

Burning of breaker contacts is determined visually. Failure of a sensor or switch elements - the easiest way to detect it is to use the method of installing a known-good unit. The lubrication system sensor valve is also checked using the same method. An incorrectly set ignition timing is visible from the fuzzy operation of the engine. It can be eliminated by adjustment using special probes.

The ignition coil increases the voltage to several kilovolts so that the discharge can ignite a spark at the spark plug electrodes. The secondary winding is made of a fairly thin wire; most often it burns out. Although a breakdown between the turns or onto the housing is also possible. The same troubles can (but less often) happen to the primary circuit. Everything is revealed using resistance measurements.

Switching elements

These include switches (high-low, turns, engine stop, etc.) as well as brake and neutral sensors and the ignition switch. You can easily “ring” them with a tester, finding out which contact group is not working.

As can be seen from all of the above, the wiring on Izh Planet is without any special secrets or complex elements, all its parts are easily diagnosed and repairs should not cause difficulties.

Now we advise you to watch the video, which shows in detail and clearly the assembly of the Izh Planet 5 circuit.

Content:

But pay special attention to the fact that the electrical circuit is designed not only for 12 volts, there is also a high-voltage cable (connecting the coil and the spark plug), which cannot be checked with a regular ohmmeter.

In this case, we look to see if there is a spark at the coil output and at the output at the spark plug contact. Now in detail about the main wiring components of the Izh Planet.

Installing electronic ignition on Izh Jupiter 5 yourself

How to install the modulator and Hall sensor so that the BSZ system works correctly was described above in the text. A new ignition coil, which has two outputs, is installed in place of the old coil. The high-voltage wire from each spark plug goes to the corresponding coil fastening elements.

Switch - in any place protected from water. Correct installation of the BSZ elements will ensure sparking for the Jupiter 5 engine in any weather.

After installing all the equipment elements, the contactless ignition on the IZh must be configured and checked for functionality. First of all, we set the ignition timing. The use of an ordinary light bulb as “dialing” and control equipment is not allowed. It does not respond to electronic impulses.

You need to use an electronic tester as a voltmeter. We measure the voltage at the Hall sensor. We connect the “positive” wire of the device to the 2nd contact, and connect the “negative” wire to the 3rd contact.

We install any of the cylinders of the Jupiter motorcycle engine at the point of spark formation. It is advisable to use a strobe light for this purpose. Turn on the ignition. Turn the modulator in the direction of rotation of the crankshaft.

As soon as the voltmeter shows a sharp change in voltage, we stop the rotation and fix the position of the modulator. We similarly check sparking for the second cylinder of the engine. We don’t twist anything anymore, we just check. The engine should run smoothly, without interruptions at any speed.

With this, we can say that a contactless ignition system is installed on the Izh Jupiter 5. Motorcycles love maintenance. Installing a BSZ is a gift to the engine and the owner himself.

Installing a contactless ignition system on Izh Jupiter-5 is a fairly current topic. When setting up a BSZ on Izh Jupiter-5 BSZ, it is necessary to take into account a number of nuances that can significantly affect the operation of the equipment used.

What advantages open up to users who decide to install electronic ignition on the Izh Jupiter are described below.

Most modern motorcycles are not equipped with cams, that is, breakers. Why did the manufacturer consider them unnecessary for currently sold models? The answer is quite simple. This system is not very reliable.

Many parts used in the system are sources of trouble. The most common ones are listed below:

The ignition gaps change their original position while driving a few days after adjustment;
A spark occurs every once in a while, since the contacts regularly burn out;
Capacitors are constantly damaged;
Low spark power;
If you add two or three volts to the battery, it is quite difficult to start it. Such ignition is the reason for constant repairs while driving.

This is noticeable at idle. The speed of their passage has noticeably increased and the unnatural twitching has disappeared. The characteristic knocking sounds of iron components in the crankcase and accompanying detonations also disappeared. The handling of the Jupiter 5 motorcycle will improve simultaneously with the time it takes to gain speed.

FORGET ABOUT THE BATTERY

Motorcycles of the Izh and Java brands can be quite easily converted to batteryless ignition. I did this seven years ago and still have no complaints. What is necessary? If the motorcycle has 6 V electrical equipment, then the 7 V generator set is from Minsk or the old Voskhod (with contact or electronic ignition); if at 12 V, then at 14 V - from the new “Voskhod”. Moreover, generator rotors can be either with removable or non-removable cams (in the first case, the installation procedure is simpler). For 2-cylinder engines (with electronic ignition), an additional sensor coil and another electronic switch will be required. Finally, the adapter flanges are turned from steel on a lathe and filed by hand, with a configuration depending on the brand of motorcycle.

The conversion sequence is as follows. First, the old generator with the relay-regulator and capacitors is dismantled, and the key is removed from the crankshaft.

Then a new generator is prepared for installation. To do this, it is somewhat modernized: the key is removed from the removable rotor cam (if it is left, the rotor will be installed as with a non-removable cam), and one of the mounting ears is cut off from the stator, since it will interfere with the crankcase protective cover. Thus, for example, in a Java with 6 V electrical equipment, the stator is attached to the flange with only two M5 bolts.

The generator stator of a 2-cylinder engine undergoes a more significant modernization: in order to place the second sensor coil, a special socket is cut out opposite the first (it is best to do this during adjustment).

Before assembly, for subsequent convenience of fixing the stator, the top dead center (TDC) of a single-cylinder or right-hand piston of a 2-cylinder engine is roughly determined and the adapter flange is attached to the crankcase.

On the crankshaft axle, if the crankcase protective cover fits snugly, place and center the rotor of the new generator while turning the crankshaft (the spark plugs are removed to make it easier). First tighten only the installed standard axle bolt to the end. To prevent the crankshaft from spinning at this moment, turn on the gearbox and jam the rear wheel (put, say, a hammer handle into the spokes).

Adapter flange for motorcycles “Izh-P-Sport”, “Izh-P-4, - 5”, “Izh-Yu-4, - 5”.

Modification of the generator stator.

Electrical wiring diagram for connecting a new 2-cylinder motorcycle generator:

1 - generator stator, 2 - ignition switch, 3 - electronic switch units, 4 - ignition coils, 5 - spark plugs.

Having secured the rotor, determine the moment of spark formation, that is, the position when the piston in the Java-350 engine does not reach TDC by 2.8...3.3 mm, Java-250 - 3.3...3.7 mm, single-cylinder “Izha” - 3.0...3.5 mm, 2-cylinder - 2.5...3.1 mm (in this position, the groove on the rotor should be aligned with the protrusion on the frame of the sensor coil, and the gap between them should be within 0 .3±0.05 mm). Then the stator is finally fixed.

The piston of the left cylinder on 2-cylinder motorcycles is adjusted in a similar way. Apply the second sensor coil to the stator so that the protrusion of its frame is located opposite the groove on the rotor. Mark the socket, cut it out and fasten the coil with screws, maintaining a gap of 0.3 ± 0.05 mm.

For a complete set on a converted motorcycle, a sound signal and a turn relay from Minsk or Voskhod, operating on alternating current, are used.

Connect the new generator according to the diagram shown. In this case, old electrical wiring is used. The switches are installed in the box where the battery was located.

And one last thing. The circuit does not require maintenance during operation and is configured once - during installation.

Retro style

Nowadays the fashion for old and vintage cars and motorcycles is actively developing. Models from 30 to 50 years ago are kept in barns and distant villages to be restored to their original form. The idea of this style is a complete or partial restoration of the motorcycle to its factory appearance. The closer and better the work is done, the better the tuning of IZH Planet 5 with your own hands looks photo:

Do not think that it is so simple, because even for such a relatively new model, it is becoming increasingly difficult to find original spare parts. Particularly expensive are fragile dashboards, original trunks and dented gas tanks. You'll have to hunt for these details. It will be very expensive to restore Soviet chrome and paint all chips and scratches. This style is suitable for true connoisseurs of the brand and those who prefer to spend hours and days in the garage.
