Noise

Possible symptoms of starting system trouble are as follows:

•Starting motor does not run (or runs slowly).
•Starting motor runs but fails to crank engine.
•Abnormal noise is heard.
•Starting motor does not stop running.

Proper diagnosis must be made to determine in which of the battery, wiring harness, starting motor (including magnetic switch) and engine the cause of each trouble lies.

Before removing the starting motor, check the following items to identify most possible causes of trouble.

1)Condition of trouble

2)Tightness of battery terminals (including ground cable connection on engine) and starting motor terminals

3)Discharge of battery

4)Mounting of starting motor
