Charging Circuit Without Load

Charging circuit test connections:

INSPECT CHARGING CIRCUIT WITHOUT LOAD

HINT: If a battery/generator tester is available. connect the tester to the charging circuit as per the manufacturer's instructions.

1. If a tester is not available, connect a voltmeter and ammeter to the charging circuit as follows:
- Disconnect the wire from terminal B of the generator and connect it to the negative (-) lead of the ammeter.
- Connect the positive (+) lead of the ammeter to terminal B of the generator.
- Connect the positive (+) lead of the voltmeter to terminal B of the generator.
- Ground the negative (-) lead of the voltmeter.

2. Check the charging circuit as follows:
With the engine running from idle to 2,000 rpm, check the reading on the ammeter and voltmeter.

Standard amperage:
10 A or less

Standard voltage:
13.5 - 15.1 V

If the voltmeter reading is more than standard voltage. replace the voltage regulator.

If the voltmeter reading is less than the standard voltage. check the generator.
