Section 14-02: Generator, Integral Regulator—Internal Fan Type
1994 Mustang Workshop Manual
DESCRIPTION AND OPERATION
Integral Generator/Regulator
When the engine is started:
Generator (GEN) (10300) begins to generate alternating current (AC).
The alternating current (AC) is converted to direct current (DC) by the rectifier (10304) .
Current is supplied through the vehicle's system through the output stud located on the rear of the generator .
Generator output current is determined by the voltage at the 'A' circuit (battery sense voltage).
'A' circuit voltage is compared to a set voltage internal to the generator regulator (10316) .
Generator regulator controls the generator field current to maintain proper generator output.
Set voltage will vary with temperature.
Set voltage is typically higher in the winter.
Set voltage is typically lower in the summer.
Varying set voltage allows for better battery recharge in the winter.
Varying set voltage reduces the chance of overcharging the battery (10653) in the summer.
