Starting System: Description and Operation

Battery voltage is applied at all times from the positive battery terminal to the ignition switch and the normally open starter solenoid contacts. When the ignition switch is turned to START and the park/neutral position switch is closed, battery voltage is applied to the starter relay. The starter relay energizes and applies battery voltage to the starter solenoid coils. The starter solenoid coils energize and the starter solenoid contact closes. Battery voltage is applied to the starter motor and the starter motor engages to start the engine.
