Generator Circuit

Battery Positive Voltage (B+) Output

The generator output is supplied through battery positive voltage (B+) output connection to the battery (10655) and electrical system.

I Circuit

The I circuit, or ignition switch circuit is used to turn on the following:

• voltage regulator (VR) (10316)
• ignition switch (11572) which is powered up with the ignition switch lock cylinder (11582) in the RUN position
• the indicator circuit 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 battery voltage. Voltage is used by the voltage regulator to determine generator output. This circuit is also used to supply power to the generator field coil, 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 (GEN) (10346) to the voltage regulator. This voltage, typically one-half battery voltage, is used by the voltage regulator to turn off the indicator.
