COMPONENTS
A Delco charging system is installed on all vehicles.
This negative-ground system consists of two primary
components: an alternator with an integral regulator
and a battery. The non-repairable, non-adjustable regu
lator is a solid-state device located within the alternator
housing.
The standard equipment alternator is rated at 42
amps and the optional, heavy-duty alternators are rated
at 55. 63, 70 and 85 amps.
Alternator
The alternator (fig. 1E-1) is belt-driven by the engine.
Its major components are front and rear housings, sta
tionary windings (stator), rotating field winding (rotor),
rectifying diodes and regulator.
The rotor assembly is supported in the front (drive
end) housing by a ball bearing and in the rear (slip ring
end) housing by a roller bearing. The bearings have
sufficient lubricant for the life of the alternator and do
