F 350 4WD Pickup V8-7.3L DSL Turbo VIN F (1994)
Voltage Regulator: Description and Operation
OPERATION
With voltage applied, the regulator is activated, allowing current to flow from the A (sensing) circuit to the alternator field coil.
The alternator generates an AC output, which is converted to a DC output by a rectifier assembly internal to alternator; this DC output is then
supplied to the vehicle through the B+ terminal.
The stator circuit is used to feed back a voltage signal from the alternator to the regulator, this voltage (typically half battery voltage) is used by the
regulator to turn OFF the indicator.
