Charging System - Generators & Regulators: Description

Charging system consists of a Powertrain Control Module (PCM), generator, Malfunction Indicator Light (MIL) and battery. Generator consists of a rotor, stator, rectifiers, front and rear covers and drive pulley. Generator is serviced as a complete unit only. Voltage regulation is controlled by the PCM. Electronic Voltage Regulator (EVR) is not a separate component, but a circuit located within the PCM. If EVR circuit is defective, PCM must be replaced.
