The starting system includes the battery, starter motor, solenoid, ignition switch, circuit protection and wiring connecting the components. An inhibitor switch is included in the starting system to prevent the vehicle from being started with the vehicle in gear.
When the ignition key is turned to the START position, current flows and energizes the starter's solenoid coil. The solenoid plunger and clutch shift lever are activated and the clutch pinion engages the ring gear on the flywheel. The switch contacts close and the starter cranks the engine until it starts.
To prevent damage caused by excessive starter armature rotation when the engine starts, the starter incorporates an over-running clutch in the pinion gear.
The easiest way to test the performance of the starter is to perform a voltage drop test.
The battery must be in good condition and fully charged prior to performing this test.
- Connect a voltmeter between the positive and negative terminals of the battery.
- Turn the ignition key to the START position and note the voltage drop on the meter.
- If voltage drops below 11.5 volts, there is high resistance in the starting system.
- Check for proper connections at the battery and starter.
- Check the resistance of the battery cables and replace as necessary.
- If all other components in the system are functional, the starter may be faulty.
Many automotive parts stores have starter bench testers available for use by customers. A starter bench test is the most definitive way to determine the condition of your starter.
REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4, 5, 6 and 7
- Disconnect the negative battery cable.
- Raise and support the vehicle safely.
When removing the hard shell connector at terminal "S", grasp the plastic shell. Do not pull on the wire.
- Disconnect the starter electrical harness.
- Remove the upper starter bolt.
- Support the starter and remove the lower bolt.
- Remove the starter from the vehicle.
- Position the starter in the vehicle.
- Install the upper and lower bolts. Tighten to 15-20 ft. lbs. (20-27 Nm).
- Connect the starter electrical harness. Tighten the starter cable nut to 80-124 inch lbs. (9-14 Nm).
When installing the hard shell connector, be careful to push it straight on and make sure it locks in position with a notable click or detent.
- Lower the vehicle.
- Connect the negative battery cable.
