Starting System: Description and Operation

CIRCUIT OPERATION
With the ignition key in the "START" position, battery voltage is transferred through the ignition switch to the clutch start switch or the transmission position switch. The clutch start switch is used on those vehicles equipped with a manual transmission while the transmission position switch is used on those vehicles equipped with an automatic transmission.

When the clutch pedal is depressed, the clutch start switch is closed and battery voltage is applied to the starter solenoid windings. When the manual selector is in either "P" or "N," the transmission position switch is closed and battery voltage is transferred to the starter solenoid windings. In each case, this causes the shift lever to push out the drive assembly, engaging it with the flywheel. This action will also cause the contacts in the starter solenoid to close, providing voltage to the starter motor.

Once the engine starts, an override mechanism allows the drive assembly to turn at the same speed as the flywheel. Once the ignition key is released, placing the ignition switch in the "ON" position, the windings in the starter solenoid are de-energized and the return spring returns the drive assembly to its original position and opens the contacts.
