Operation
The starting circuit includes the battery, starting motor, ignition switch (or starter button), neutral switch,
and
related wiring.
The starter motor magnetic switch
coils are magnetized when the starter button is closed.
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 over-running clutch protects the armature from excessive speed until
the starter button is opened, at which time the torsion spring causes the pinion to disengage.
