6G-2 CRANKING SYSTEM
GENERAL DESCRIPTION
CRANKING CIRCUIT
The cranking circuit consists of the battery, starting motor, ignition switch, and related electrical wiring. These com-
ponents are connected electrically.
Only the starting motor will be covered in this section.
STARTING MOTOR CIRCUIT
The magnetic switch coils are magnetized when the ignition switch is closed.
The resulting plunger and pinion drive lever movement causes the pinion to engage the engine flywheel gear
and the magnetic switch main contacts to close, and cranking takes place.
When the engine starts, the pinion over-running clutch protects the armature from excessive speed until the
switch is opened, at which time the return spring causes the pinion to disengage.
