Generator General Description

Generator with internal regulator - Internal Fan and Regulator Type is used on these vehicles.

The Generator (GEN):
^ Supplies current to the vehicle's electrical system.
^ Charges the battery.

With the ignition switch in the RUN position:
^ voltage is supplied through the I circuit to the Voltage Regulator (VR).
^ The generator warning indicator turns on (lamp prove-out).
^ The voltage regulator turns on, allowing current to flow through the A circuit to the generator field coil.

With the engine running:
^ The generator produces Alternating Current (AC), which is changed to Direct Current (DC) by the rectifier diodes.
^ Current is supplied to the vehicle through the generator B+ terminal (stud).
^ The generator warning indicator turns off.







^ Generator output is controlled by the voltage regulator.
