Preparing for the test
1. Turn off the ignition.
Note. To avoid further problems when connecting the generator, make sure that the two clamps or their connections are not damaged during the test.
2. Connect a digital voltmeter to the terminal «IN» generator and to the positive (+) battery terminal.
Check condition
Start the engine, turn on the headlights, heater fan and other consumers of electrical energy and read the readings on the voltmeter.
Result of checking
1. The voltmeter should show a voltage of less than 0.3 V.
2. If the voltage is 0.3 V, then the wire is damaged or it is not securely connected to the generator and battery terminals.
To test the wire, connect the terminal «IN» and the positive terminal of the battery with an additional wire with a fusible insert.
Check that the wire is securely connected to the terminals, and also make sure that the wire insulation is not melted from overheating. Correct the problem and recheck.
3. Finally, turn off all electrical consumers and stop the engine.
