Description & Operation

Vehicle is equipped with a 90-amp generator which includes a rotor mounted on bearings in 2 end frames, a stator, 6 diodes, an internally-mounted voltage regulator and an integrally-mounted shield.

Generator operates with 2 wire connections and a ground path through the mounting bracket. The first wire connection is the BAT (output) terminal. This terminal must be connected to the battery during operation. The second wire connection is through the battery warning indicator light to terminal "L" of the generator. This circuit initiates generator charging.

If battery voltage drops below a predetermined amount, Powertrain Control Module (PCM) will increase idle speed to increase generator output. If charging circuit malfunctions, PCM will illuminate the battery warning indicator light.
