Description & Operation

This vehicle is equipped with a generator which includes a rotor mounted on bearings in 2 end frames, a stator, 6 diodes and an internally-mounted voltage regulator.

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. On models equipped with 3.0L engine, generator charging initiates when engine speed is above 2500 RPM.

On all models, if battery voltage drops below a predetermined amount, Powertrain Control Module (PCM) will increase idle speed to increase generator output. On models equipped with 2.2L engine, if charging circuit malfunctions, PCM illuminates the battery warning indicator light. On models equipped with 3.0L engine, if charging circuit malfunctions, PCM will command Body Control Module (BCM) to illuminate the battery warning indicator light.
