1 DESCRIPTION AND OPERATION
The alternator regulator has been
designed to exercise automatic con-
trol over the charging system, and
also to compensate for seasonal teni-
perature changes. The Autolite elec-
tro-mechanical regulator is factory
calibrated and is not to be adjusted.
The alternator regulator is com-
posed of two control units, a field re-
lay and a voltage limiter, mounted as an
assembly (Fig. 1). Refer to wiring
Diagram Manual Form 7795P-68 for
locations of wiring harnesses. Sche-
matics are shown in Group 19
of this manual.
FIELD
RELAY
The field relay serves to connect
charging system voltage to the field
circuit when the engine is running.
Charge lndicator Circuit -Light
When the ignition switch 1s closed,
the charge indicator light shunted with
a 15-ohm resistor supplies adequate
starting field current.
When the alternator builds up
enough voltage to close the field re-
lay contacts, full voltage is applied
to the field, and the charge indicator
light goes out.
