Starter Controls - PRESTOLITE Solenoid: Description

Combined starting switch and pinion shift solenoid unit mounted on starter. Solenoid has a series (pull-in) winding and a shunt (hold-in) winding. Both windings are energized to engage the starter pinion with the flywheel and to close the main starting switch contacts. Series winding is short circuited when switch contacts close but shunt winding remains energized to hold contacts closed.
