NOTE:
If battery is fully charged, disable ignition system. Crank engine for about 15 seconds to partially discharge battery.
- Ensure generator belt tension is correct. Turn ignition off. Disconnect battery negative cable. Disconnect output wire from terminal "B" of generator. Securely connect test equipment as shown. See Fig 1. Attach engine tachometer, and connect battery negative cable.
- If voltmeter indicates battery voltage, go to next step. If voltmeter indicates zero volts, check for open wire between positive battery terminal and generator terminal "B", blown fusible link, or poor ground.
- Start engine. Turn headlights on high beam, and operate blower motor at high speed. Quickly increase engine speed to 2500 RPM, and observe maximum current readout on ammeter. Ammeter reading should not be less than minimum output amperage. See GENERATOR OUTPUT SPECIFICATIONS table. If generator output is not as specified, remove and bench test generator.
