Additional Troubleshooting Procedures
1. Simple check 
 • Battery voltage, working voltage.
 • Sufcient 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 certied genuine parts , then observe operation.

 • Make sure unit is lled with enough coolant.
 • Make sure gas valve is open. Check for suitable gas pressure.
 • Check whether the battery is sufciently 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.
