a) Connect the voltmeter and ammeter to the "B" terminal of the generator.
Note: If you have a tester for checking the generator and battery, connect it in accordance with the manufacturer's instructions.
If you don't have a tester, connect the following circuit:
- Disconnect the wire from the generator terminal "B" and connect it to the negative terminal of the ammeter.
- Connect the wire from the positive terminal of the ammeter to the "B" terminal of the generator.
- Connect the positive terminal of the voltmeter to the "B" terminal of the generator.
- Connect the negative terminal of the voltmeter to ground.
Note: Use an ammeter and leads that can measure current levels greater than 120 A.
b) Start the engine, wait until the radiator fan turns on, let the engine run without load at a speed of 3000 rpm.
c) Bring the engine speed up to 2000 rpm and record it, turn on the high beam headlights, measure the voltage at terminal "B".
13.9-15.1 V?
- Yes - proceed to step 2.
- No - disassemble and check the generator components.
2. Check the output voltage. Bring the engine speed to 2000 rpm and fix it, turn on the high beam headlights, rear window heater, heater fan at maximum power and measure the battery voltage.
Below 13.5V?
- Yes - proceed to step 3.
- No - add load (radio, rear brake lights, etc.)
3. Measure the current.
Above 60 A?
- Yes - the charging system is normal.
- No - disassemble and check the generator components.
Note: If the indicator remains on, check the circuit or replace the alternator.
