Generator

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.
- the generator warning lamp 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 lamp turns off.
- Generator output is controlled by the voltage regulator.
