Additional Troubleshooting Procedures
1. Simple check
• Battery voltage, working voltage.
• Sufcient fuel supply – check that fuel valve is open?
• Is the entrance and pressure reducer to gas solenoid valve properly open?
• High voltage normal or not: spark plug).
• Speed sensor signal normal or not.
• Observe exhaust gas (color, smell, sound and feel).
• Replace the suspected parts only with a new certied genuine parts , then observe operation.
• If fault is repaired then, observe start and listen to engine.
• If the fault appears again, verify that genuine parts are being used and properly installed.
Common Faults and Repair Methods of Genset
Genset will not start
Perform the following methods:
1. Basic check:
• Make sure unit is lled with engine oil.
• Make sure unit is lled with enough coolant.
• Make sure gas valve is open. Check for suitable gas pressure.
• Check whether the battery is sufciently charged or not.
• Check the main power input when starting the unit automatically.
• Check the power indicator light on digital controller to make sure it’s on.
• Check Gas ow pressure: turn the transition nut on pressure regulator to adjust proper gas ow .
• Battery voltage test: use a multi-meter to test the battery voltage, if voltage is 12.6 V, battery has enough
power; if voltage is below 12.6V, recharge battery.
• Cylinder wire check: see picture below, the gap between the conductor and engine is 3-5mm, start the
start motor, check for spark.
• Spark plug check: contact spark plug with engine block. Initiate
starter motor, observe whether the spark plug is sparking to the
ground contact on engine block. If no spark, replace plug.
