Cranking Circuit Introduction

The cranking circuit consists of the battery, starting motor, ignition switch, and related electrical wiring. These
components are connected electrically.

Starting Motor Circuit Description

• 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.
