The Ford Starter Motor is a series
parallel wound

machine using a moving pole shoe
actuated positive pre-engaged
pinion.
The

battery supply is not
connected
until
the
pinion is in
engagement
unless
tooth abutment is
encountered.
The starter motor is protected
by
an overrunning
clutch which dis-
engages the
drive
between
the
armature
and ring gear as soon as the
engine starts and so prevents over
revving of the
armature.
A remote relay connects the
starter to the battery when the starter
(ignition) switch is operate1.
When the starter is not in use, one
of the field coils is connected directly
to ground through a set of contacts.
When the starter is first connected to
the battery a large current flows
through the grounded field coil, ac-

the fully seated position,
during the time that the starter is
turning the engine.
5. Snug all bolts, then torque them
to specification.
