Starting System - Starter Motor

The starter motor is a 12-volt unit that has the starter solenoid mounted on the drive end housing and functions as follows:

• The current flows through the solenoid energizing coil until the solenoid plunger is at the end of its travel.
• The plunger closes a set of contacts that bypass the energizing coil, letting the holding coil engage the starter drive and pass starting current to the starter motor.
• The motor is energized when the starter solenoid contacts are closed.
• The starter drive engages the flywheel ring gear and starts the engine.
• An overrunning clutch in the starter drive protects the starter motor from excessive speed when the engine starts.
