Note: Before checking the starter condition, make sure the battery is fully charged.
1. If the starter does not rotate when the ignition key is turned to the START position, first make sure that the selector lever is in the "P" or "N" position (models with automatic transmission) / fully depressed clutch (models with manual transmission).
2. Check the battery charge level, assess the condition and reliability of the battery and starter contact terminals.
3. If the starter rotates properly, but the engine does not turn over, the drive assembly with the overrunning clutch should be replaced.
4. If the starter does not turn, despite the correct clicking of the traction relay, the cause of the failure may be a faulty battery, oxidation of the main contact terminals of the starter, or failure of the electric motor of the starter assembly itself. The possibility of engine jamming is also possible.
5. If no clicking sound is heard when turning the key, check the battery, the fuse link of the starting circuit and the starter relay. The magnetic starter itself may be faulty.
6. After disconnecting the coil assembly, deactivate the ignition system. Make sure that starting the engine is not possible.
7. Connect a voltmeter between the positive battery terminal and the B+ terminal of the starter.
8. Turn the ignition key to the START position and read the voltmeter reading.
9. If the measurement result exceeds 0.5 V, then there is a break or short circuit in the starter circuit wiring, perform the necessary repairs. If the voltage is OK, proceed to the next step of testing.
10. Connect a voltmeter between the positive battery terminal and the M terminal. Turn the key to the START position and read the reading.
11. If the measurement result exceeds 0.5 V, then there is an open or short circuit in the starter circuit wiring, perform the necessary repairs.
12. A more detailed check of the starter can be performed on a workbench using a special diagnostic tester - ask in car accessory stores.
