Starter Performance Test

1. Remove the engine compartment covers Service and Repair.

2. Remove the starter.

3. Clamp the starter firmly in a vise.

4. Disconnect the motor wire from the M terminal.

5. Make the connections for this test using the thickest (gauge) wire possible (preferably the same gauge as used on the vehicle).

8. Disconnect the battery from the starter body as shown. If the pinion retracts immediately, it is working properly.





9. Reconnect the motor wire to the M terminal.

10. Connect the starter to the battery as shown, and confirm that the motor runs.





11. If the electric current meets the specification when the battery voltage is at 11.5 V, the starter is working properly.
