Component Location Index
Circuit Operation
The generator generates an AC voltage in its windings
as it is belt-driven by the engine. The rectifier converts
this AC voltage to DC.
The voltage regulator, a component which is included
in the generator frame, has a primary function of con-
trolling the generator’s output to meet electrical sys-
tem requirements. This regulator controls the charge
warning light.
The METER fuse CB-4 supplies battery voltage to the
charge warning light. With the engine not running and
the starter switch in ON, terminal L of the regulator is
grounded internally, providing ground for the charge
warning light, and the indicator lights up. With the en-
gine running and the generator charging, terminal L
voltage rises and the indicator goes out. If the genera-
tor fails to charge, terminal L grounds internally, which
then provides ground for the charge warning light, and
the indicator lights up.
