The starting system includes the battery, starter motor, solenoid, ignition switch, circuit protection and wiring connecting the components. An inhibitor switch is included in the starting system to prevent the vehicle from being started with the vehicle in gear.
When the ignition key is turned to the START position, current flows and energizes the starter's solenoid coil. The iron plunger core is drawn into the solenoid coil. The lever and pin which are connected to the drive assembly engage the starter drive to the ring gear on the flywheel. When the iron core is completely in the coil its contact disc closes the circuit between the battery and starter motor terminals. The current travels to the starter which cranks the engine until it starts or the ignition switch is released from the START position.
To prevent damage caused by excessive starter armature rotation when the engine starts, the starter incorporates an over-running clutch in the pinion gear.
