In 1970, the IZH Planet 3 model appeared in the production program of the Izhevsk Motor Plant.
Unlike its predecessor with the index “2,” the motorcycle received a new shaped gas tank, a more powerful engine and direction indicators.
Unification of the electrical circuit with other models is a traditional way to reduce costs
Connecting wiring Izh Planet 3
The sources of electric current on motorcycles of the IZH models are direct current generators (Fig. 62) with parallel excitation and a rated power of 45 W at 1700 rpm.
Possible generator malfunctions:
sticking of brushes in brush holders;
contamination of the inter-lamella grooves or wear of the collector; short circuit of the generator windings to the housing or their turn circuit; the armature touching the stator due to improper installation of the stator, armature or wear of the right main bearing of the crankshaft; generator polarity reversal due to incorrect wire connection. To determine the causes and eliminate generator malfunctions, you must: 1. Remove the right crankcase cover. 2. Disconnect the wires from the terminal block. 3. Unscrew the screws securing the stator and remove it. 4. Unscrew the armature mounting bolt. 5. Screw the armature puller from the tool kit into the hole and remove the armature. 6. Remove the key from the groove of the axle shaft. After disassembling, wipe the parts with a cloth soaked in gasoline and inspect. Remove burrs from the working surfaces of the lamellas using fine-grained glass sandpaper. If the commutator is heavily worn, it can be machined on a tapered mandrel (taper 1:5), deepen the inter-lamella grooves to a depth of 0.5 mm and remove burrs. Paint over damaged insulation of excitation coils and bare areas of their terminals with enamel. Inspect the right axle shaft of the crankshaft and the cone hole of the armature. If there are nicks, clean them with fine-grained sandpaper. If there is large radial play, replace the right crankshaft main bearing. To install the generator in place:
1. Insert a key into the groove of the axle shaft and install the armature. 2. Place a spring washer and a breaker cam on the armature mounting bolt. 3. Screw in and tighten the bolt, making sure that the armature shaft antenna fits into the cam groove. 4. Lift the brush wires in the brush holder and install the stator in place, while the pin on the right half of the crankcase should fit into the groove at the end of the stator. 5. Secure the stator with screws and connect the wires to the terminal block. After disassembling and assembling the generator, it is necessary to check the ignition timing and, if necessary, adjust it. Ignition adjustment is described in the “Ignition System” section.
The reverse current relay consists of an electromagnet core 4, an armature 3 with a spring 12, two contacts 1, 2 and a yoke 13. Two windings are wound on the core: a thin shunt winding (SHO) and a thick series winding (CO). In the free state and at idle (low) engine speeds, the contacts are open and all consumers receive power from the batteries. As the generator armature speed increases, the voltage in the network increases. Accordingly, the current passing through the thin winding (WW) increases, the attractive force of the core overcomes the force of the spring, the armature is attracted to the core, the contacts are closed, and the electric current from the generator goes to charge the battery and to other consumers. As soon as the generator voltage drops below e. d.s.
batteries, the relay contacts will open under the action of the spring.
Those who own a motorcycle with six-volt electrical equipment know that the weakest point is charging. Either the battery suddenly runs low and starting the motorcycle is a problem, then the charge disappears somewhere and magically returns, sometimes you have to ride at night without a headlight so as not to completely drain the battery... The electronic relay-regulator is an analogue of the PP-1 (voltage regulator and reverse current relay) and will save you from these problems forever. No additional modifications to the motorcycle wiring diagram are required. The circuit contains a minimum of parts that have many analogues.
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.
