Taurus V6-182 3.0L VIN 1 FI Flex Fuel (1997)
Alternator: Description and Operation
Generator Circuit Description
CIRCUIT DESCRIPTION
The generator circuits function as follows:
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:
^
Turns on the voltage regulator.
^
Is HOT with the ignition switch in the RUN position.
^
Turns the warning 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:
^
Senses the battery voltage. The voltage regulator uses this to determine the Generator (GEN) output.
^
Supplies power to the generator field coil.
^
Is HOT at all times.
^
Is protected by a fuse in the power distribution box.
S Circuit
The S circuit, or stator circuit is used to feed back a voltage signal from the generator to the voltage regulator.
^
Voltage is typically half of the battery voltage (B+).
^
Voltage is used by the voltage regulator to turn off the warning indicator.
