Battery voltage is applied to the Ignition Switch at all times through Fusible Link A. When the Ignition Switch is turned to "START," battery voltage is applied through the closed contacts of the Ignition Switch to the Starter Solenoid at terminal "S" of the Starter Solenoid, the Hold-In Coil and Pull-In Coil of the Starter Solenoid are energized with the Pull-In Coil grounded through the Starter Motor. The coils, when energized, work together to pull in and hold the Plunger of the Starter Solenoid. As the Plunger is pulled in, it closes the Starter Solenoid contacts and causes the Shift Lever to rotate, engaging the Drive Assembly to the Flywheel. With battery voltage applied directly to the Starter Motor through the closed Solenoid Contacts, the Starter Motor begins to rotate the Drive Assembly as the Drive Assembly comes in contact with the Flywheel. The Starter Motor continues to rotate to crank the Engine through the Drive Assembly-Flywheel gear combination.
Battery voltage is removed from the Starter Solenoid terminal "S" when the Ignition Switch is released from the "START" position. The Pull-In and Hold-In Coils are de-energized and the return spring in the Starter Solenoid causes the Plunger to disengage the Drive Assembly from the Flywheel. As the Plunger returns, the Plunger opens the Solenoid Contacts removing battery voltage from the Starter Motor.
