Charging System - Generator: Description

System consists of 110-amp generator (3.0L) or 125-amp generator (3.8L), internal voltage regulator, battery, Powertrain Control Module (PCM), charge warning indicator, related fuses and wiring. PCM and generator communicate using pulse-width modulated signals. A dedicated line communicates desired charging rate from PCM to generator, and a second dedicated line communicates load from generator to PCM.

Charge warning indicator should illuminate with ignition on, engine off. Charge warning indicator should not illuminate with ignition off, or with engine running. Generator and regulator cannot be serviced separately, and must be replaced as an assembly.
