DESCRIPTION AND OPERATION

Sequence of Operation

  1. The ignition switch (11572) is turned to the START position.
  1. The starter solenoid (11390) is energized, creating a magnetic field in the solenoid coil.
  1. The iron plunger core is drawn into the solenoid coil.
  1. A lever connected to the starter drive (11350) engages the drive pinion gear to the flywheel ring gear.
  1. When the iron plunger core is all the way into the coil, its contact disc closes the circuit between the battery (10653) and the motor terminals.
  1. The current flows to the motor, and the starter drive cranks the flywheel (6375) and the crankshaft (6303) .
  1. As current flows to the motor, the solenoid pull-in coil is bypassed.
  1. The hold-in coil keeps the starter drive engaged with the flywheel .
  1. The starter drive remains engaged until the ignition switch is released from the START position.

    An overrunning clutch in the starter drive protects the starter motor (11002) from excessive speeds during the brief period before the driver releases the ignition switch from the START position (as the engine starts).
