CIRCUIT OPERATION
The GENERATOR supplies DC voltage to operate the vehicle's electrical systems and to recharge the BATTERY while the engine is running. The voltage output of the GENERATOR is controlled by the internal solid state Regulator.

When the IGNITION SWITCH is turned to "ON," Battery voltage is applied through Fuse C-7, Fuse C-11 and the Charge Indicator to the Regulator within the GENERATOR. When the GENERATOR is not rotating, the Regulator provides a ground and causes the Charge Indicator to light. Voltage from Fuse C-7 also generates a magnetic field around the Field Coil. As the engine starts and the GENERATOR begins to rotate, a voltage is generated in the Starter. The Regulator senses this voltage and takes control of the field current.

AC voltage is generated in three Stator coils inside the GENERATOR. This AC voltage is converted to DC voltage in the Rectifier Bridge. DC voltage output is then applied to the vehicle's BATTERY and the electrical supply circuits at the "BAT" terminal of the GENERATOR. A separate output voltage is provided to the Charge Indicator. Since equal voltage is now being applied to both sides of the Charge Indicator, the Indicator loses its ground and goes out.

The Regulator is connected to Battery voltage through the "BAT" terminal of the GENERATOR. When the BATTERY is fully charged the Regulator decreases the GENERATOR field excitation. This reduces the voltage output of the GENERATOR to prevent the BATTERY from overcharging. When the BATTERY has been discharged or is heavily loaded, the Regulator increases the field excitation and voltage output of the GENERATOR.
