Circuit Description

Battery Positive Voltage (B+) Output

The 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 circuit, is used to turn on the voltage regulator. This circuit is powered up with the ignition key in the RUN position. This circuit is also used to turn the indicator 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. This voltage is used by the regulator to determine the generator output. This circuit is also used to supply power to the generator field coil. This circuit is connected back to the load distribution point and is a protected circuit.

'S' Circuit

The 'S' circuit, or stator circuit, is used to feed back a voltage signal from the generator to the regulator. This voltage, typically half battery voltage, is used by the regulator to turn off the indicator.
