Visible Faults
1. Visually inspect the engine for the following faults:
•
Missing components
•
Damaged components
•
Damaged electrical cables or loose electrical
cables
•
Oil leaks
•
Fuel leaks
2. Check the following items:
•
Check for smoke from the exhaust when the
engine is cranking. If smoke is seen during
cranking, there may be a mechanical fault in the
engine. Refer to "Low Compression (Cylinder
Pressure)".
•
Check for the proper level of fuel, oil and
