Alternator: Description and Operation

GENERATOR

The generator has an internal voltage regulator that is not repaired separately. A new generator and voltage regulator must be installed as an assembly.

All police interceptor/long wheel base (LWB) taxi applications are equipped with a one-way clutch (OWC) in the generator pulley. The OWC pulley temporarily disengages the generator rotor from the front end accessory drive (FEAD) system during high deceleration rates on the engine, which may increase belt life and decrease belt chirp. A new OWC pulley and generator/voltage regulator must be installed as an assembly.
