Electrical System and Components
Solenoid Shift Electric Starters
Operation – Solenoid Shift Starter
When power is applied to the starter the electric
solenoid moves the drive pinion out onto the drive
sha and into mesh with the fl ywheel ring gear. When
the pinion reaches the end of the drive sha it rotates
the fl ywheel and cranks the engine.
When the engine starts and the start switch is released
the starter solenoid is deactivated, the drive lever
moves back, and the drive pinion moves out of mesh
with the ring gear into the retracted position.
