Attention: The contact terminals of the electrical wiring must be securely fastened and not oxidized!
1. If the starter does not turn, first make sure that there is voltage at the traction relay terminal (minimum 10 V). If negative, check the condition of the starter current circuit wiring.
2. To verify that the starter operates properly at full battery voltage, do the following:
- With no gear engaged, turn the key to position «ON»;
- Bridge terminals 30 and 50 of the starter with a wire with a cross section of at least 4 mm2.
3. If the starter works flawlessly, the cause of the malfunction should be sought in the wires to the starter. If the starter does not work, it should be checked in the removed state (see chapter 5).
21. The starter does not rotate when the key is turned to position «Start»
1. Low battery.
2. Bridge terminals 30 and 50 of the starter: if it rotates, check the wire connected to the ignition switch for an open, also evaluate the condition of the starter switch.
3. The ground wire is broken, or the quality of its terminal connection is broken.
4. The weakening of the current strength due to a violation of the quality or oxidation of the contact connections.
5. There is no voltage at the traction relay terminal as a result of a broken electrical wiring or damage to the starter switch.
22. Starter rotates slowly and does not turn the crankshaft
1. Low battery.
2. Filled with summer oil.
3. The passage of current is difficult due to poor-quality contacts.
4. The carbon brushes are loose on the commutator, stuck in the guides, worn, broken, oily or dirty.
5. Insufficient distance between brushes and commutator.
6. The collector is grooved or burnt and oily.
7. No voltage on the terminal (minimum 8 V).
8. Broken bearing.
9. Faulty traction relay.
23. Starter «grasps», but provides cranking the engine only jerkily
1. Defective gear drive.
2. The gear is dirty.
3. Damaged flywheel/drive plate ring gear.
24. Starter gear does not disengage from flywheel/drive plate ring gear
1. Dirty or damaged gear drive components.
2. Faulty traction relay.
3. Return spring is weak or broken.
25. The starter continues to work after releasing the ignition key
1. The traction relay is stuck, - immediately turn off the ignition and replace the traction relay.
2. The ignition lock does not turn off - disconnect the battery, replace the lock.
