Common Faults and Repair Methods of Generator
11. TROUBLESHOOTING
1. Simple check
•
Battery voltage, working voltage.
•
•
Entrance and pressure reducer gas solenoid valve properly open or not.
•
High voltage normal or not spark plug .
•
Speed sensor signal normal or not.
•
Observe exhaust gas (smell, color, sound,feel).
•
A comprehensive check and the focus on one part or one target.
2. Parts replacing inspect
•
Replace the suspected parts with a new and same one, then observe operation.
•
If the fault disappeared, place back the suspected parts, then start the engine and observe it.
•
If the fault appears again, verify the damaged parts , use the new and same part to replace it.
•
If faced with a comprehensive fault, pleas shrink the sinking scope, and then use the replacement
