Electronic ignition on IZ Jupiter 5 - is it worth doing?

You can ride a motorcycle without worrying about its technical condition. But the owners of the “iron horse” love their cars, take good care of them, carry out the necessary maintenance, showing true care for their beloved friend.

Modernization and tuning of Jupiter 5 brings a lot of pleasure to the owners of this type of transport. Many people have one dream - to install contactless ignition on Izh Jupiter 5. “Ancient” contact-type systems have long since become obsolete. They are no longer used on modern motorcycles and cars. One headache:

• loss of gap between the contacts of the breaker;
• changing the geometry of contacts;
• not constant sparking;
• failure of high-voltage wire insulation;
• unstable operation of the high-voltage coil;
• impossibility of starting the engine when the battery voltage is low.
• the spark does not ignite the combustible mixture in the engine cylinder

Electronic ignition on Izh Jupiter 5 with a Hall sensor allows you to completely get rid of these shortcomings.

Non-contact ignition on Izh - understanding unclear terms

1. BSZ – contactless ignition system;
2. Modulator – metal disk (steel 0.8-1.0 mm thick), plate, curtain. Installed on the axis of the ignition timing mechanism (distributor shaft). Produces “generation” of magnetic pulses to the Hall sensor.
3. Switch – an electronic device that supplies electrical impulses to the ignition coil;
4. A Hall sensor is a device capable of detecting the presence or absence of a magnetic field. If there is a field, a control pulse goes to the switch. The sensor position is fixed.
5. The ignition coil is a converter of pulses coming from the switch into high-voltage pulses supplied directly to the spark plugs.

Installation and configuration instructions

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.

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.

In particular, setting the gaps between the contacts of the interrupting device should be done in the following order:

1. First of all, the crankshaft is turned by the kick starter.
2. 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.
3. 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.

Making ignition elements for IZH Jupiter 5 with your own hands

You can manufacture individual elements and make electronic ignition for Izh Jupiter 5 with your own hands. To do this, you will need to make your own modulator. The quality of its manufacture determines the reliability of the entire plant.

The modulator is made perfectly symmetrical. A fixed curtain should cover 30 degrees of the area when it is rotated. Once again, it must be emphasized that the modulator is the determining element in the motorcycle ignition system. The smooth operation of the engine is determined by this small device. If the modulator is properly manufactured, then its shutter should not, in the open state, block the magnet and magnetic circuit of the Hall sensor.

The closed state must ensure their simultaneous closure for the passage of magnetic flux. The switch must receive clear pulses of a certain size from the Hall sensor; ensuring this condition is the task of the modulator.

To perform electronic ignition on Izh Jupiter 5 with your own hands, you also need to make a plate for attaching the Hall sensor. BSZ does not require periodic adjustment of the ignition timing. But for initial adjustment it is necessary that the Hall sensor be able to rotate. The plate must have slots.

The Hall sensor itself, together with the plate, is installed on a corner, which can also be made independently.

All the main elements for installing electronic ignition on the Izh Jupiter 5 motorcycle have been manufactured. You need to buy an ignition coil, purchase a switch and a Hall sensor. These BSZ elements cannot be made independently. You will also need a mounting wire. It is advisable to change the spark plugs - the spark may be weak on them. After all the issues have been resolved, the last thing left to solve is how to install electronic ignition on the Izh Jupiter 5.

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:

1. It is checked by measuring their resistance of current-carrying conductors and insulation. If the generator is damaged, it will become noticeably hot.
2. — the output voltage will differ significantly from the nominal level or be absent.
3. Although the electrical circuit includes short circuit protection, it happens that the automation does not work and most often the output transistor burns out.

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 is connected to the corresponding fastening elements of the coil.

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

In what cases is ignition adjustment necessary?

During the operation of the vehicle, the owner faces many problems. The most serious failure is related to the engine. In order to spend significant funds on major repairs, it is necessary to monitor the technical condition of the motorcycle and carry out preventive work, including adjusting the valves and valves (video author - Hana Rulyu).

If you do not monitor the SZ, then the motorcycle engine may not reveal its full potential and will not work at full capacity. This can lead to a reduction in its service life. An ignition adjustment is necessary if the engine is running poorly, the muffler or carburetor is firing. True, before setting up the SZ, you should make sure that the cause of the malfunction is in it.

It happens that the flywheel bolt, which connects the two halves of the crankshaft, comes loose, begins to play and does not work well. Sometimes he even cuts the key.

Setting up the SZ may be necessary after repairing lock 5. The installation and connection itself are carried out according to the diagram.

Transition to 12 volt circuit

The use of electrical parts from later model motorcycles will inevitably affect the voltage change, because:

1. The 12V system is more advanced;
2. Has increased sparking;
3. More “tenacious” in our climate zone.

For reference: The price of many parts is affordable for motorcycle owners, so modernization will not break the bank.

We hope that the proposed algorithm for modifying the standard electrical system of the IZH Jupiter 3 motorcycle with video and photo materials will help you (see also the IZH Planet 3 wiring diagram). And you will use this method to upgrade your own motorcycle.

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).

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.

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 reliably the required dimensions are observed, the lower the likelihood of problems occurring after implementing the system, that is, there will be no need to adjust it using 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 implementation of the 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:

1. Disconnect the wires from the battery and remove the generator cover.
2. 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.
3. 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.
4. 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:

1. Place the motorcycle on a stand and place the gearbox in neutral.
2. Remove the right crankcase cover and unscrew the spark plug.
3. 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.
4. Loosen the screw securing the contact.
5. Place the probe between the contacts and adjust the tightening of the eccentric screw until the probe passes the contacts with little resistance.
6. 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:

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

How to set the ignition?

When setting up the ignition, problems often arise with setting the signal advance angle. A voltmeter will help fix this problem. Looking ahead, it should be said that a device designed for a minimum of 15 V and 10-50 kOhm (internal resistance) is ideal. A voltmeter is connected directly to the terminals. Next, you should bring the piston to the position at which sparking occurs. Then turn on the ignition and turn the modulator until the readings on the device change. You can track the charge on the spark plug by the voltage on the sensor, which should jump. This value is equal to tenths of a volt close to the on-board power supply of the equipment. As soon as the spark is “groped”, you need to fix the position of the modulator directly on the generator shaft. This is usually done with a bolted connection. When adjusting the ignition, constantly short-circuit the high-voltage wires to the frame of the unit. Otherwise, excessive load on the ignition cannot be avoided, which can lead to its failure.
