The IZH Planet 5 wiring diagram has a simple design: a single-wire DC network is provided by a 12-volt battery, which is charged by a 100–140-watt generator. The role of the negative wire in the electrical circuit is performed by the metal frame, and since the rest of the wiring has a positive charge, their short circuit is often the main cause of the malfunction.

Generator device
Battery
To supply all components, a low-power energy storage device of exactly 12 volts is required, since there is no starter in IZH Planet 5. The task of the lead-acid battery is only to supply voltage to the ignition system and the excitation winding of the generator during start-up.
Battery
Ignition system
In IZH Planet 5, the ignition coil converts low-voltage voltage to high-voltage and transfers it to the spark plug. That, in turn, is responsible for the spark that detonates the fuel. In order for detonation to occur only in the desired position of the piston, there is an ignition interrupter.
Ignition system
In the factory, this model has a classic ignition system, which requires periodic cleaning of the breaker contacts and adjusting the gap between them.
Installing contactless coolant on a motorcycle gives:
- timely powerful sparking;
- reduction of vibration level;
- reduction in fuel consumption.

The alternator (Fig. 30) is single-phase with excitation from permanent magnets.
The generator rotor is mounted on the cone of the right semi-axis of the engine crankshaft, the stator is in the generator cover or on a base fixed in the engine crankcase. The stator has two separate windings: charging and power. The charging winding is connected directly to the switch and serves to power the engine ignition system, the power winding through the rectifier-regulator provides power to lighting devices, alarms and battery charging.
Rice. 30. Generator and ignition sensor:
1 - rotor; 2 - stator; 3 - ignition sensor
The ignition system is powered by alternating current, the remaining consumers through a rectifier-voltage regulator with direct current.
The generator does not have sliding contacts and rubbing parts, its maintenance is reduced to monitoring the state of electrical insulation, wire connections and the reliability of the rotor and stator fastening.
The serviceability of the generator set (generator-rectifier - voltage regulator) is checked using a DC voltmeter with a scale division value of 0.1 V. The voltmeter is connected to the "+" terminal of the rectifier-voltage regulator and "mass". At medium engine speeds with the battery connected and the high beam headlights on, the voltage should be 13.7 ... 14.7 V. A voltage deviation from the indicated values \u200b\u200bindicates a malfunction of the rectifier-voltage regulator or generator.
Remove the generator from the engine in the following order:
disconnect the wires of the generator and the ignition sensor from the rectifier-voltage regulator, switch, main harness;
remove the generator cover with the stator, unscrew the four screws securing the stator and the screw of the bracket for attaching wires to the generator cover, disconnect the stator from the generator cover;
unscrew the rotor fastening bolt, using the screw from the chain link axle squeezing tool as a puller (screw it into the rotor shaft), remove the rotor.
If the stator is mounted on a base fixed in the crankcase, unscrew the four screws securing the stator to the base, remove the stator with the harness.
Install the generator in reverse order.
5.4.2. Motorcycle battery IZH 7.107-01
The battery is the source of power when the engine is not running. The "-" terminal of the battery is connected to the "mass" of the motorcycle. Reverse connection of the terminals is unacceptable, as it leads to failure of electronic devices, other components of electrical equipment and the battery itself.
The actuation, operation and maintenance of the battery are described in the attached battery instruction manual.
A capacitor with a capacity of 2200 microfarads is connected in parallel with the battery, designed to smooth out the rectified voltage ripples and ensure the normal operation of motorcycle electric power consumers in the event of a battery failure or its absence.
5.4.3. Rectifier-voltage regulator for motorcycles IZH 7.107-01
The rectifier-voltage regulator (Fig. 31) or voltage regulator is designed to rectify the alternating current of the generator, maintain the generator voltage within the specified limits and ensure reliable operation of the entire electrical equipment system, the connection of which to the system is different (see the electrical diagram in the appendix 7).
Rice. 31. Scheme of the rectifier-voltage regulator BPV 21-15
In order to avoid violation of the thermal mode of operation of the rectifier-regulator, periodically (at least once every six months) it is necessary to clean it with a brush from dust and other contaminants. It is not allowed to clean with metal objects and break the factory seal during the motorcycle warranty period.
5.4.4. Installation of motorcycle ignition IZH 7.107-01

After 2500-3500 km, check the condition of the candle, in case of carbon deposits and oiling, rinse the candle in clean gasoline and dry it.
Check the gap between the spark plug electrodes with a feeler gauge. When adjusting the gap, carefully bend the side electrode. Install the spark plug in the socket with the sealing ring.
5.4.9. The tip of the spark plug motorcycles IZH 7.107-01
The tip of the candle (Fig. 33) connects the spark plug to the high-voltage wire of the ignition coil and ensures that radio interference is reduced to acceptable standards. During operation, it is recommended to periodically check the reliability of fastening the wires in the tip and in the ignition coil, blow the tip to remove dust between the screen and the housing, wipe the tip inside. The wire must be screwed into the lug until it stops.
Rice. 33. Candle tip:
1 - body; 2 - resistor; 3 - wire; 4 - screen
5.4.10. Headlight of motorcycles IZH 7.107-01
The headlight has two lamps: the main light with two threads (dipped and main beam) and parking light. To better use the light qualities and reduce glare, the headlight must be adjusted. Before adjusting, place the motorcycle on a horizontal platform perpendicular to the Screen at a distance of 10 m. The load on the motorcycle during adjustment is the driver. Adjustment should be made with the low beam on in accordance with the markings of the screen (Fig. 34), while the longitudinal vertical plane of symmetry of the motorcycle should intersect with the screen along the line AB.
Rice. 34. Headlight adjustment
5.4.11. Brake light switches for motorcycles IZH 7.107-01
The brake light switches for the front and rear wheels are used to turn on the light signal when the motorcycle is braked. Adjustment of the moment when the signal is switched on in case of a change in the position of the rear wheel brake lever is carried out by moving switch 1 (Fig. 35) with its loosening. The brake light must come on before the wheel starts to brake.

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.
Which affects for the better the lighting, the operation of the turn signal interrupter and the brake light. The serviceability of the rectifier-voltage regulator and at the same time the serviceability of the generator on IZH motorcycles is checked using a test lamp. When the engine is off, the control light is on, when the engine is running it goes out. This indicates that the generator and rectifier-regulator are working.
Care of the rectifier-regulator consists in cleaning from dust and dirt.
Dirt slows down the cooling of the rectifier-regulator, which leads to its failure.

Improving the car, the plant made a number of changes to it. In particular, the fixation and clarity of operation of the switches IZH P101 and IZH P102 and the switch on the steering wheel have been improved. The optical element of the Hella company in the headlight was replaced by the Soviet FG 137, and the IZH UP1 lamps of the direction indicators were replaced by unified lamps 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 Planet-sport model, the electrical equipment of which is unified with Jupiter-4.
However, already now the owners of Planet-Sport can use a number of IZH Yu-4 electrical appliances without significant alterations. These include generator 28.3701 (if it is sold without a breaker and a capacitor, they can be taken from the old IL GP1); direction indicator lights 16.3726; optical element of headlight FG 137; rear lamp FP146; speedometer SP102; rechargeable battery 6MTS-9.
To install the turn signal interrupter IZH RP2SM-10 into the headlight housing, it is necessary to make an additional bracket from a steel strip 1-1.5 mm thick and replace the plug-in tips with round ones. After the same alteration of the tips, the combined switches IZH P101-20 and IZH P102-20 from the IZH Yu-4 motorcycle can also be used on Planet-Sport. To do this, pressing the fixing antennae with an awl or a knitting needle, remove the plug tips. They are cut off and round lugs are crimped and soldered 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 also soldered to the black wire.
The improvement of 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 the electrical equipment of the Planet-Sport scheme, which is in many ways similar to the schemes 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 the fuse 25 and the rectifier 26, power is supplied to the terminal (2) of the connecting panel in the headlight housing and then to the terminal (3) of the ignition switch 9. When the key is turned to position I, the terminals (3-2 - 1 and 5 -6). Now, from the terminal (1) of the lock, the current goes to the terminal (5) of the connecting panel, from it to the emergency ignition switch 11, and through its closed contacts to the terminal (1) of the connecting panel and then to the primary winding of the ignition coil 21 (the second end of the primary winding - the "-" terminal is connected to the breaker). Thus, the circuit of the motorcycle ignition system is turned on.
If the engine does not run due to the absence of a spark at the plug, check if high voltage is being 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 no spark appears between the wire and the cylinder when the crankshaft is rotated by the kick starter, there is no high voltage. The reason for this is found as follows. When the ignition is turned on, a 12-volt test light is used to check whether power is supplied to the “+” terminal of the ignition coil. If not, then check the entire circuit, starting from the battery. A common cause of no voltage is loose or oxidized terminals, or a faulty fuse.
Having achieved that a normal voltage appears on 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 gives only separate flashes at start-up, and a white coating appears on the breaker contacts, it means that the capacitor has failed (rarely, but this happens).
With the correct clearance, clean breaker contacts 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, so it is replaced). A bad spark plug can cause the engine to misfire 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 battery 24 (or rectifier 26 when the engine is running) is supplied through the terminals (3 and 1) of the ignition switch 9 to the 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 switch 19 of the direction indicators. From it, through the terminals (6 and 7) of the connecting panel, it goes to the lights 10 and 28 of the direction indicators. The control 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 failure of the direction indicators most often is the lack of "mass" in the lamps when their fastening to the frame is loosened, oxidation or loosening of the connections of the tips with wires, contacts in the lamp sockets.
To speed up troubleshooting, the circuit is checked from the idle consumer to the power source. To determine the operability of the relay 6 of the direction indicators without dismantling it, you must first make sure that the terminal (5) of the connecting panel is energized, and the brown wire of the relay is securely connected to ground. Then check the continuity of the circuits going to the direction indicator lamps by connecting terminal (5) with terminals (6 and 7) of the connecting panel with a separate wire. The lights of the right (terminal 6) or port side (terminal 7) and the control lamp 16, if the circuits are in good condition, should burn without blinking. Then disconnect the pink relay wire from terminal (9) and connect it to terminals (6 and 7) of the connection board. 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 (power of each 25 W) connected in parallel. Connect the “plus” of a constant voltage of 12 volts to the red wire, “minus” to the brown one, and control lamps to the pink one. With a working device, the lamps should flash at a frequency of 90 ± 30 per minute.
Farah. It contains the main part of the wiring diagram, the turn signal relay, the neutral 3 and oil pressure warning 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 models of motorcycles, the turn signal breaker is mounted on the frame under the gas tank.
Consider the electrical circuit of the head, parking and clearance light. With the ignition 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-dipped beam switch 19. Then through the terminals (11 and 12) of the connecting panel - to the thread of the high or low beam of lamp 2.
The position light in the headlight (bulb 1) and in the rear lamp 29 lights up when the switch 11 is activated and current flows through the contacts (5 and 6) of the ignition switch 9.
If the ignition key 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.
Lamps that dimly glow when the engine is not running indicate that the battery is not fully charged. If this is observed in all engine operating modes, it means that the voltage in the lamp supply circuit drops sharply. In this case, check the electrical connections of the power and ground wires, clean and tighten the screw and plug connectors, the contacts in the lamp sockets of the headlights and lanterns. 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 changes, it is advisable to mark the differences of your motorcycle in the circuit printed here so that, using it, you can always easily and quickly find the right circuit and determine the malfunction.
