Note: this check is necessary to evaluate the status of the wiring from the output «IN» alternator to the positive battery terminal.
1. Turn off the ignition (key position «OFF»).
2. Disconnect the wire from the terminal «IN» generator. Connect wire «+» ammeter to output «IN» generator, and the wire «-» - to the disconnected wire of the generator.
Connect wire «+» voltmeter to output «IN» generator, and the wire «-» - to the positive battery terminal.
3. Start the engine.
4. Turn on the headlights and heater fan. Increase the engine speed until the current shown by the ammeter is 20 A.
5. Read the voltmeter. Rated value: less than 0.2 V. If the measured voltage is greater than the rated voltage, check the condition of the wire between the terminal «IN» generator and «+» battery.
6. After completing the test, let the engine idle, then turn off the consumers.
