Charging System: Description and Operation

DESCRIPTION
The Generator/Voltage Regulator is belt driven by the the engine and generates power to keep the Battery fully charged and to operate the vehicle's electrical systems.

OPERATION
The Generator/Voltage Regulator produces power in the form of alternating current. The alternating current is changed to direct current by the Rectifier. The IC Voltage Regulator automatically adjusts the current to the Field coil to maintain the Generator/Voltage Regulator output voltage within prescribed limits to correctly charge the Battery and operate the vehicle's electrical systems.

The IC Voltage Regulator's voltage control circuit is turned "ON" when the Ignition Switch is in "START" or "RUN" and voltage is applied to it through the Charge Warning Indicator and the Diode Junction Box. When the Ignition Switch is "OFF", the control circuit and current to the Field Coil is turned "OFF".

Charge Warning Lamp
With the Ignition Switch in "START" or "RUN", battery voltage is applied to the Charge Warning Indicator.

When the output of the Generator/Voltage Regulator is above a prescribed voltage limit, the Charge Warning Indicator will have battery voltage present at both terminals, there is no current flow and the Charge Warning Indicator does not illuminate.

When the output of the Generator/Voltage Regulator is below a prescribed voltage limit, the IC Voltage Regulator grounds the Charge Warning Lamp. The Charge Warning Indicator illuminates.
