Generator Circuit

Circuit Description

Battery Positive Voltage (B+) Output

The generator output is supplied:

• Through battery positive voltage (B+) output connection.
• To the battery (10653) and electrical system.

'I' Circuit

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

• Generator regulator (10316).
• Ignition switch (11572) which is powered up with the ignition switch 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.
• By the generator regulator to determine generator output.
• To supply power to the generator field coil.

The 'A' circuit is:

• Connected back to the load distribution point.
• A protected circuit.

'S' Circuit

'S' circuit, or stator circuit is:

• Used to feedback a voltage signal from the generator (GEN) (10300) to the generator regulator .
• Typically one-half battery voltage.
• Used by the generator regulator to turn off the indicator.
