- Disconnect wire from generator terminal "B". Connect ammeter and voltmeter as indicated. See Fig 1. Operate engine at idle and increase to 2000 RPM. Check generator output. See GENERATOR OUTPUT SPECIFICATIONS table. If output voltage is high, replace voltage regulator and recheck. If output voltage remains low, repair or replace generator.
- With engine at 2000 RPM, place heater blower switch on highest setting and turn on headlights (high beam). Ammeter reading should be 30 amps or more. If amperage output is less than 30 amps, repair or replace generator.
