Ford Mustang Service Manual: Starter Motor - 4.6L
Starting System (Description and Operation)
Starter Motor
The starter motor is a 12-volt unit that has the starter solenoid mounted on the drive end housing and functions as follows:
- The current flows through the solenoid energizing coil until the solenoid plunger is at the end of its travel.
- The plunger closes a set of contacts that bypass the energizing coil, letting the holding coil keep the starter drive engaged and passing starting current to the starter motor.
- The motor is energized when the starter solenoid contacts are closed.
- The starter drive engages the flywheel ring gear and starts the engine.
- An overrunning clutch in the starter drive protects the starter motor from excessive speed when the engine starts.
Starter Relay
The starter interrupt relay consists of:
- pull in coil and contacts
- When the ignition switch is in the START position:
- the pull-in coil is activated and pulls the contacts together.
- current passes through the starter relay from the engine compartment power distribution box to the starter solenoid.
Clutch Pedal Position (CPP) Switch
The CPP switch for:
- a manual transmission closes when the clutch pedal is depressed, completing the starting circuit.
- an automatic transmission is a jumper inserted in place of the CPP switch to complete the circuit.
Starter System - Operation
When the ignition switch is turned to the START position the starter relay switches power to the starter solenoid causing the starter motor to engage as long as:
- the clutch pedal is depressed (manual transmission only).
- the digital transmission range (TR) sensor is in PARK or NEUTRAL (automatic transmission only).
