Starting Circuit

The starter circuit is activated when the ignition switch is turned on. This opens a second switch in the solenoid, permitting a second flow of electricity from the battery to the starter motor. The engine cranking circuit is made up of a battery, starting motor, ignition switch, and electrical wiring. When the ignition switch is placed in the "start" position, the solenoid windings are energized and the resulting shift lever movement causes the drive pinion gear to engage the flywheel ring gear, and cranking takes place. When the engine starts, an overrunning clutch (part of the drive assembly) protects the armature from too much speed until the switch is opened. At this time, a return spring causes the pinion gear to disengage from the flywheel.
