CRANKING SYSTEM
DIAGNOSIS
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

harness, (including ignition and starter 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.
1) Condition of trouble
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
