Checking the serviceability of the generator can be done on a motorcycle without disassembling the generator.
To carry out the work you will need a multimeter.
1. Place the motorcycle on the center stand or side stand.
2. Disconnect the battery by removing its fuse.
3. Remove the right cover of the power unit.
4. 6mm
unscrew the nuts securing the five “upper” wires of the generator. In order not to confuse the wires during subsequent assembly, we mark them or tie them with thin wire so that we get a cable.
5. Check the short circuit of the stator windings to ground. To do this, touch the probes of the multimeter to the generator housing and alternately the three terminals of the windings. The ohmmeter should show infinity.
6. Check the stator windings for breaks. To do this, touch the probes of the multimeter in turn to all three terminals of the stator windings. The resistance should be about 8 ohms.
7. Check for a short to ground in the excitation (rotor) winding. To do this, touch the probes to the generator housing and one of the terminals of the brush assembly. The ohmmeter should show infinity.
8. Check the field winding (rotor) for open circuit. To do this, install probes on both brushes. The ohmmeter should not show infinity.
We replace faulty parts.
The road version of the IZH Planet 5 motorcycle differed favorably from other domestic analogues by the use of an oil pump, which made it possible to abandon the scheme for pre-mixing fuel with oil.
In addition, subsequent modifications were distinguished by their contactless ignition system, independent of the battery, and modified kinematics.
This allowed:
- To set the motorcycle in motion “from the pusher” - by turning on the ignition, the owner engaged second gear and, using his own efforts, pushing the motorcycle forward, started the engine;
- Operation without a battery was possible during daylight hours (a battery was still required for the side lights and headlights to operate).
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.
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.
Electrical equipment IZH Planet 5
The motorcycle uses 12-volt electrical equipment. The electrical wiring of the IZH Planet 5 motorcycle is single-wire, the role of the negative wire is performed by a metal frame.
Among the main components are:
- Power supplies;
- Ignition system;
- Headlight;
- Side lighting and turns.
For reference: as is customary in auto and motorcycle construction, modification of components and assemblies allows you to reduce the cost of products. For consumers, the advantage is that the price is low and a number of parts are interchangeable.
Generator
The motorcycle is equipped with a three-phase alternating current generator with an electromagnetic excitation circuit.
The principle of its operation is as follows:
- Electric current from the windings located on the stator is supplied to the rectifier;
- It converts it to direct current;
- And supplies it to consumers through the ignition switch.
The instructions provided include the following items:
- Voltage regulator with rectifier BPV-14-10;
- Generator rotor;
- Generator stator with windings;
- Current collector brushes;
- Ignition system cam (battery);
- Ignition system contact unit
For reference: on three-phase generators of the IZH Planet 5 motorcycle, the windings are connected according to a “star” or “delta” circuit. The rectifier is installed as a separate unit, and the IZH Planet 5 electrical wiring is connected to it.
Headlight
For reference: with such a generator, IZH Planet 5 did not need an external current source when starting the engine. Therefore, the battery was not included in the electrical equipment.
The head light circuit includes:
- headlight lamp (35W);
- blue indicator lamp (2W);
- headlight parking light (4W);
- rear brake light lamp (15W).
Control devices
The following control devices are installed on the motorcycle:
- speedometer with daily and total mileage counters;
- tachometer with indicator lamps for direction indicators and headlights;
- engine temperature indicator;
- voltmeter.
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.
A diode bridge for current rectification and a voltage regulator assembled in one unit are mounted on the Izh Planet 5 generator (they are not even highlighted in the Izh Planet wiring diagram manuals).
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.
Maintenance Features
Often during operation it is necessary to correctly set the gap between the contacts of the breaker. To do this, you need tools and a diagram to see which elements need to be dismantled.
The algorithm of actions is as follows:
- place the motorcycle on the stand;
- turn on neutral;
- unscrew the spark plug from the cylinder;
- remove the engine crankcase cover;
- turn the crankshaft until the contacts are as open as possible;
- using a screwdriver, loosen the locking screw;
- using a special feeler gauge, set the gap to 0.35-0.45 mm and fix it with a screw;
- we collect everything in reverse sequence;
- turn on the ignition and start the engine. Its stable operation at idle indicates that the adjustment has been correctly performed.
In general, all the wiring of IZH Planet 5 is very easy to do with your own hands.
The need for such work often arises when operating a motorcycle:
- in wet weather, driving in the rain for a long time (oxidation or dampness of electrical contacts);
- when traveling over rough terrain, replete with vegetation and bushes (mechanical damage to wiring);
- when used in winter (snow and slush stick to the wires and can damage them).
Often the sound signal suffers during operation. Its malfunctions manifest themselves in the form of deterioration in sound quality.
To restore its functionality, you must perform the following procedure:
- loosen the locknut using an open-end wrench;
- turn on the ignition;
- press the button to turn on the sound signal;
- use a screwdriver to adjust the tone;
- repeat the procedure until we get a clear and loud sound;
- tighten the control nut.
Conclusions: we are confident that this article will help you in servicing motorcycles of the IZH family (see also the article about). Both the attached diagrams and description will help you avoid making mistakes during operation.
The history of motorcycles from the Izhmash plant begins in the 30s of the last century. During this time, many modifications of the IZH 1 - 6 bike were released. They are very popular. The article is devoted to the IZH Planet 5 bike, discusses its features, the IZH Planet 5 wiring diagram, and talks about maintenance.
Motorcycle Features
The IZH Plante 5 motorcycle has the original name IZH 7.107. Just like the IZH 6, it belongs to the middle class of motor vehicles, designed for movement on roads with any surface. The main feature is the use of an oil pump; when refueling there is no need to add oil to the tank, as well as a contactless ignition system that operates independently of the battery.
It became possible to start a motorcycle from a pusher. To do this, you need to turn on the ignition, second gear and, when pushing the bike forward, the engine starts. True, without a battery, operation is possible only during daylight hours.
The Fifth Planet can be equipped with a cargo trailer and a passenger stroller. To reduce the clutch release effort, the bike has a clutch consisting of 7 pairs of discs. Vibration dampers are installed on the cylinder ribs. An important feature of this series is the presence of hydropneumatic suspension with disc brakes, which contributed to a smooth ride. The power is 22 horsepower, the maximum possible speed is 120 km/h. The volume of the two-stroke single-cylinder engine is 346 cm3. The power unit has good traction at low speeds.
Electrical equipment IZH Planet 5
Motorcycles IZH 3, 4, 5 and 6 are equipped with 12-volt electrical equipment. The wiring of IZH Planet 3 and 5 consists of standard 12-volt incandescent lamps, a set of instruments and switches.
The electrical wiring is single-wire, there is no negative wire, its role is played by the bike frame. Planet 4 is similar to the electrical circuit of Planet 5.
The electrical circuit includes the following main components:
- generator;
- turns and side lighting;
- Headlight;
- contactless ignition system.
The power source on both IZh 5 and 6 motorcycles is a battery and a 3-phase alternating current generator. In the generator, alternating current from the windings is supplied to the rectifier and converted into direct current. Power is supplied to all consumers through the ignition switch (video author: altevaa TV).
The head light circuit of the IZH Planet 5 motorcycle consists of: a headlight bulb, a blue turn-on indicator light, a parking light bulb, and a rear brake light bulb.
The following control devices are installed on the bike:
- tachometer, on which there are indicator lights for the headlights and turns;
- speedometer showing total and daily mileage;
- power engine temperature indicator;
- voltmeter.
