Electrical circuit of the motorcycle IZH Planet Sport I - parking light lamp; 2 - main light lamp; 3 - neutral control lamp; 4 - resistor; 5 - oil pressure control lamp; 6 - direction indicator relay; 7 - diode block (decoupling); 8 - speedometer scale illumination lamp; 9 - ignition lock; 10 - front direction indicators; II - headlamp switch and emergency ignition switch; 12 - hand brake brake light switch; 13 - relay-regulator; 14 - neutral lamp switch; 15 - high beam control lamp; 16 - direction indicator control lamp; 17 - generator control lamp; 18 - sound signal; 19 - light and direction indicator switch, sound signal switch; 20 - spark plug; 21 - ignition coil; 22 - foot brake brake light switch; 23 - generator; 24 - storage battery; 25 - fuse; 26 - rectifier; 27 - oil pressure sensor; 28 - rear direction indicators; 29 - rear lamp.

Improving the car, the plant made a number of changes to it. In particular, the fixation and accuracy of operation of the IZH P101 and IZH P102 switches and the steering wheel switch have been improved. The optical element of the "Hella" company in the headlamp was replaced by the Soviet FG 137, and the IZH UP1 direction indicator lamps were replaced by unified lanterns 16.3726. There are other innovations as well.

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

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

To install an IZH RP2SM-10 turn signal interrupter in the headlight housing, an additional bracket must be made of a steel strip 1-1.5 mm thick and the plug-in lugs must be replaced with round ones. After the same alteration of the handpieces, the combined switches IZH P101-20 and IZH P102-20 from the motorcycle IZH Yu-4 can be used on Planet-Sport. To do this, squeezing the fixing antennae with an awl or knitting needle, remove the plug tips. Cut them off and crimp and solder round tips at the stripped ends of the wires. At the IZH P101-20 switch, a blue lead wire 130-150 mm long with a plug tip is also soldered to the black wire.

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

Ignition system... This is perhaps the main system, because the motor cannot work without it. Let's trace and remember its electrical circuit. From the storage battery 24, through the fuse 25 and the rectifier 26, power is supplied to terminal (2) of the connecting panel in the headlamp housing and then to terminal (3) of the ignition lock 9. When its key is turned to position I, the terminals (3-2 - 1 and 5 are closed) —6). Now, from the terminal (1) of the lock, the current goes 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 engages the motorcycle ignition circuit.

If the engine does not run because there is no spark on the plug, check for high voltage. 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 rotates with 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 the ignition is turned on with a 12-volt control lamp, it is checked whether power is supplied to the "+" terminal of the ignition coil. If not, then check the entire circuit, starting from the battery. Loose or oxidized terminals and a defective fuse are common causes of no voltage.

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

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

With the correct clearance, clean contacts of the breaker and a working capacitor, the reason for the absence of a spark on the candle may be a malfunction of its plastic cap (breakdown to ground) or the ignition coil (it is non-separable, therefore it is replaced). A poor quality spark plug can cause the engine to malfunction or make it difficult to start. Alarm and lighting system

Direction indicator... When the ignition is turned on (the key is in position I), electricity from the storage battery 24 (or rectifier 26 with the engine running) is supplied through the terminals (3 and 1) of the ignition switch 9 to terminal (5) of the connecting panel. The power wire of the relay 6 of the direction indicators, the sound signal 18 and the "positive" wire of the 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 indicator switch 19. From it, through the terminals (6 and 7) of the connecting panel, it goes to the lamps 10 and 28 of the direction indicators. The indicator lamp 16 of the direction indicators is also connected to the terminals (6 and 7) of the connecting panel through the block of diodes 7.

The reason for the refusal in the operation of direction indicators is most often the absence of "mass" in the lanterns when they loose their attachment to the frame, oxidation or weakening of the connections of the tips with wires, contacts in lamp holders.

To speed up troubleshooting, the circuit is checked from the idle consumer to the power source. To find out the operation of the direction indicator relay 6 without dismantling it, you must first make sure that voltage is supplied to the terminal (5) of the connecting panel, and the brown wire of the relay is reliably connected to ground. Then check the serviceability of the circuits going to the direction indicator lamps by shorting the terminal (5) with the terminals (6 and 7) of the connecting panel with a separate wire. The lanterns of the right (terminal 6) or left side (terminal 7) and the control lamp 16, if the circuits are in good condition, should be on without blinking. Then, disconnect the pink wire of the relay from terminal (9) and connect it to terminals (6 and 7) of the junction panel. With a working relay, the lights of the starboard or port side should flash at a frequency of 60 to 120 per minute.

The relay removed from the motorcycle is checked using two A12-21-3 control 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, "minus" to the brown wire, and control lamps to the pink wire. With a working device, the lamps should flash at a frequency of 90 ± 30 per minute.

Headlight... It contains the main part of the wiring diagram, the direction indicator relay, the neutral 3 and oil pressure control lamps 5, the lamp 8 illuminating 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 breaker is mounted on the frame under the gas tank.

Consider the electrical circuit of the head, parking and side lights. When the ignition is on (the key is in position I), power is supplied to the 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. Further, through the terminals (11 and 12) of the connecting panel - to the thread of the high or low beam of the lamp 2.

The side light in the headlamp (lamp 1) and in the rear lamp 29 comes on when the switch 11 is triggered and current flows through the contacts (5 and 6) of the ignition switch 9.

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

Weak lights when the engine is not running indicate that the battery is not fully charged. If this is observed in all operating modes of the engine, it means that the voltage in the lamp supply circuit drops dramatically. In this case, check the electrical connections of the power and ground wires, clean and tighten the screw and plug connectors, contacts in the lamp holders of the headlights and lamps. Check the integrity 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 changes, it is advisable to include the differences between your motorcycle in the diagram printed here so that, using it, you can always easily and quickly find the desired circuit and determine the malfunction.

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 are often encountered by owners of the IZH P5 motorcycle.

How is the wiring done for IZH Planet 5

Most of those in operation today are equipped with a contactless ignition system. This makes it possible to use the motorcycle even without a battery - but the lights and direction indicators will not work. Some owners remove the battery on their own or remove the main fuse if the electrical circuit is damaged and there is no time or desire to deal with it. But, according to the current traffic rules, the operation of a motorcycle with such malfunctions is prohibited, and therefore the Planet 5 wiring must always be in perfect condition.

The IZH wiring diagram is designed for a voltage of 12 volts, not 6, which should be taken into account by the motorcycle owner. The circuit uses the metal frame of the motorcycle as the negative wire: all wires are positively charged, and shorting them to the frame is often the main cause of wiring failure.

Typical wiring diagram for IZH Planet

Conditionally, the wiring can be divided into 2 circuits: external appliances and ignition.

The motorcycle uses the following model of operation: with the engine running, the generator supplies voltage to the coils and provides battery charging. Already from the battery, the voltage goes to the rest of the consumers.

The problem with Planet 5 motorcycles is the lack of a separate fuse box, and often in the event of a malfunction, you have to revise all the wiring. The standard model of the IZH planet 5 wiring provides for the installation of a fuse on the positive wire of the battery. Therefore, in the event of malfunctions in the operation of external devices, but with a working ignition system, this particular fuse should be checked first.

One of the most common problems with Planet motorcycles is loss of battery charge due to a faulty generator. It is quite simple to check it yourself, the check scheme is as follows:

Guided by the knowledge of IZH Planet 5 wiring, you can easily restore the wiring on other motorcycles: the IZH wiring diagram and its connections are similar.

The history of Izhmash motorcycles 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, its features are considered, the wiring diagram of IZH Planet 5, and maintenance is described.

Motorcycle features

The IZH Plante 5 motorcycle has the original name IZH 7.107. Just like IZH 6, it belongs to the middle class of motor vehicles, intended 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 works independently of the battery.

Now you can start a motorcycle from a pusher. To do this, you need to turn on the ignition, second speed 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 supplemented with a cargo trailer and a passenger sidecar. To reduce the effort of disengaging the clutch, the bike has a clutch of 7 pairs of discs. Vibration dampers are installed on the ribs of the cylinder. An important feature of this series is the presence of a 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 revs.

Electrical equipment IZH Planet 5

On motorcycles IZH 3, 4, 5 and 6, 12-volt electrical equipment is installed. IZH Planet 3 and 5 wiring consists of standard 12 Volt incandescent lamps, a set of instruments and switches.

The wiring is single-wire, there is no negative wire, its role is played by the bike frame. Planet 4 is similar to the Planet 5 electrical circuit.

The wiring diagram includes the following main components:

• generator;
• turns and side lighting;
• Headlight;
• contactless ignition system.

The power source for both 5 and 6 IZH motorcycles is a rechargeable battery and a 3-phase alternator. In the generator, alternating electric current from the windings is fed to the rectifier, and is converted into direct current. Power is supplied to all consumers through the ignition lock (video by altevaa TV).

The head light circuit of the IZH Planet 5 motorcycle consists of: a head light bulb, a blue control light, a parking light bulb, a rear brake light bulb.

The bike has the following control devices:

• a tachometer, on which there are control lamps for the head light and turns;
• speedometer showing total and daily mileage;
• power engine temperature gauge;
• voltmeter.

Maintenance

Those who love their bike regularly monitor its technical condition. During operation, it is sometimes necessary to adjust the gap between the breaker contacts. To carry out this operation, you need an IZH 5 motorcycle circuit diagram, which shows the connection of devices, and the corresponding tools.

The procedure consists of the following steps:

1. Place the motorcycle on the footrest and engage in neutral.
2. Next, you need to unscrew the spark plugs.
3. Then remove the cover from the crankcase.
4. The next step is to ensure that the contacts are as open as possible. To do this, we need to turn the crankshaft.
5. Next, you need to loosen the locking screw with a screwdriver.
6. Using a feeler gauge, you should set a gap of 0.35-0.45 mm. We fix the gap with a screw.
7. We do the assembly in the reverse order.

With the correct clearance, the engine idles stably.

The electrical circuit of IZH 3, 4, 5 and 6 is quite simple and any driver can figure it out in order to repair it if necessary with his own hands.

Such a need may arise in the following cases:

• operating the bike in wet weather (contacts are oxidized);
• movement in an area overgrown with vegetation (mechanical damage to the wiring);
• winter trips (dirt build-up, which can damage the wiring).

On both IZH bikes 5 and 6, there may be problems with the sound signal, it may sound weaker. To regulate it, you need to loosen the lock nut, turn on the ignition and use a screwdriver to adjust the tone. After the desired tonality is achieved, it is necessary to tighten the locknut.

Video "Wiring diagram on the bike IZH Planet 5"

This video will help you understand the electrical circuit of IZH 5 (the author of the video is Dmitry Antyufeev).

Motorcycle IZH Planet 4 rectifier-regulator voltage, the main role of which is to rectify the current, charge the battery and power all electrical appliances of the motorcycle from a 100W alternator. The rectifier-regulator changes the alternating current into direct current and makes it more stable.
That has a positive effect on lighting, the operation of the turn signal interrupter and brake light. The serviceability of the rectifier-voltage regulator and, at the same time, the serviceability of the generator on motorcycles IZH is checked using a warning lamp. When the engine is turned off, the control is on, when it is running, it goes out. This indicates that the generator and rectifier-regulator are in good working order.

Caring for the rectifier-regulator consists in cleaning it from dust and dirt.
Dirt inhibits the cooling of the rectifier-regulator, which leads to its failure.

For the correct connection, the rectifier-voltage regulator on the Izh Planet 4 motorcycle, the next photo shows what color the wire is and where it is connected on the connecting block.
Legend of conclusions on the rectifier-regulator block BPV 14-10.
-x1- minus the excitation winding of the generator, the color of the H wire is black
-x2 - minus the storage battery (mass), the color of the wire Kch - brown
x3 - positive wire to the control lamp of the instrument panel, wire color Г - blue
x4, x5, x7 - phases of the stator winding of the generator, wire P color - pink
x8 - battery positive, K wire color - red

During the operation of the IZH Planet 4 motorcycle, the work of the rectifier-regulator affected the better. The lighting has become stable, the turn relay works more clearly.

Easily eliminating breakdowns of the mechanical part, motorists have difficulty if an electrician fails. Absolutely in vain, the wiring diagram of the planet Izh 5 is simple, it's easy to figure it out.

There is no need to have special stands and equipment for repairs. A minimal knowledge of electrical engineering and the simplest avometer (tester) is enough, even often you can do with just a control lamp.

Let's talk in more detail about the main wiring assemblies and possible malfunctions. Izh Planet's wiring diagram makes it easy to find a broken wire or insulation damage (for example, poor contact is always 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 candle) you cannot check it with an ordinary ohmmeter.

In this case, we look - is there a spark at the output of the coil and at the output at the contact of the candle. Let's consider in detail about the main nodes of the wiring Izh planet.

Generator

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

A diode bridge for rectifying the current and a voltage regulator assembled in one block are mounted on the Izh Planet 5 generator (they are not even singled out in the manuals for the Izh Planet wiring diagrams).

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 warm up noticeably.
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.

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 start-up. Thanks to a 12 volt battery, a stable start of the fifth planet is ensured, up to the third model the wiring was 6 volts, and the ignition is not always clear.

Possible battery malfunctions:

1. - housings, plates, electrolyte leakage.
2. - determined by measurement with a hydrometer.
3. - Revealed by measuring the resistance.
4. minus not on the body (frame) of the motorcycle - all the electronics will not work.

Ignition system

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

The main malfunctions of this unit:

1. Burnout of the breaker contacts is determined visually.
2. Failure of the sensor or switch elements - the easiest way to detect it is to use the method of installing a known-good unit. The same method is used to check the valve-sensor of the lubrication system.
3. An incorrectly set ignition timing is visible from the fuzzy operation of the engine. Eliminated by adjusting using special probes.

The ignition coil raises the voltage to several kilovolts so that the discharge can ignite a spark across the spark plug electrodes. The secondary winding is made of a rather thin wire, it most often burns out. Although breakdown between turns or on the case is also possible. The same troubles can (but less often) occur with the primary circuit. Everything is revealed using resistance measurements.

Headlight and alarm lamps.

Conventional incandescent lamps are used; it is not difficult to find a burnt-out spiral.

Switching elements.

These include switches (far-near, turns, engine stop, etc.) as well as brake and neutral sensors and an ignition switch. You can easily "ring" them with a tester, having found out which contact group does not work.

The electronic relay of turns Izh also belongs to the commutation. Its malfunction is visible by the absence of an interruption or even supplying voltage to the turn signals.

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

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