1. WIRING HARNESS INTERMITTENT
2. GENERATOR FIELD CKT SHORT TO VOLTAGE
3. POWERTRAIN CONTROL MODULE

Scheme 34

1. When Monitored: The engine running. The engine speed greater than 380 RPM.
2. Set Condition: Battery voltage is 1 volt greater than desired system voltage.

1. TARGET VOLTAGE DIFFERS FROM BATTERY VOLTAGE
2. INTERMITTENT CONDITION
3. GENERATOR FIELD DRIVER CIRCUIT SHORTED TO GROUND
