Generator Circuit Description
BATTERY POSITIVE VOLTAGE (B+) OUTPUTThe generator output is supplied through the battery positive voltage (B+) output connection to the battery and electrical system.
I CIRCUIT
The I circuit, or ignition switch circuit, is used to turn ON the Voltage Regulator (VR). This circuit is HOT with the ignition switch in the RUN position. This circuit is also used to turn the indicator lamp ON if there is a fault in the charging system operation or associated wiring circuits.
A CIRCUIT
The A circuit, or battery sense circuit, is used to sense the battery voltage (B+). This voltage is used by the voltage regulator to determine the generator output. This circuit is also used to supply power to the generator field coil. This circuit is HOT at all times.
S CIRCUIT
The S circuit, or stator circuit, is used to feedback a voltage signal from the Generator (GEN) to the voltage regulator. This voltage is:
- typically one-half battery voltage.
- used by the voltage regulator to turn the indicator OFF.
