Possible symptoms due to starting system trouble would be as follows:
- Starting motor does not run (or runs slowly)
- Starting motor runs but fails to crank engine
- Abnormal noise is heard

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

Do not remove motor just because starting motor does not run. Check following items and narrow down scope of possible causes.

2. Tightness of battery terminals (including ground cable connection on engine side) and starting motor terminals
3. Discharge of battery
4. Mounting of starting motor
