ELECTRIC STARTER SYSTEM
Outline
The starting circuit consists of the battery, starting motor, ignition switch, neutral switch and relatad elec­
trical wiring. These components are connected electrically as shown in figure below.
STARTING SYSTEM CIRCUIT
In the circuit shown in figure below, the magnetic switch coils are magnetizad when the ignition switch is
closed (turn to "START'}. The resulting plunger and pinion shift lever movement causes the pinion to
engage the engine flywheel gear, the magnetic switch main contacts to close, and engine cranking to
take place. When the engine starts, the pinion overrunning clutch protects the armature from excessive
speed until the switch is opened, at which time the torsion spring causes the pinion to disengage.
