Installation Guide
• Igniter test: use a multi-meter to test the socket voltage, it
should read 12V
Test the rst two
Corresponding positions
• Check starter motor: when generator exercises initial start,
the main shaft of the Starter motor should engage and rotate
substantially to open throttle.
If starter motor is not operating properly, replace starter.
Generator hunting elimination:
After starting generator, if there is too much irregular pattern vibration, this means generator is hunting (fre-
quency uctuation >2Hz). The power output produced while hunting will not inuence the use of electricity
(except with high precision digital equipment, which requires Low harmonic distortion and high quality electric
frequency). Still, this should be adjusted and repaired promptly.
1. General checking:
• Check whether the gas pressure normal or not.
• Check whether the fuel line is blocked.
• Check whether the speed sensor is loose or damaged.
• Check starter.
2. Measuring method:
• Connect a pressure meter in the inlet pipe, open the gas valve, observe the data on
pressure gauge.
• Observe whether the gas valve is extruded or not.
• Open the fuel switch; see if there is a hum from the solenoid valve.
• Use the multi-meter Ohm level, measure the two joints of the speed sensor, there should
be resistance.
• Check whether the electrical speed regulation has 12v DC power input.
No Power Output: Troubleshooting
After starting the generator, there is no power output under the right speed and frequency,
perform the following steps to check and solve issues:
• Check whether the battery has enough voltage (Voltage>12V).
• Check circuit for proper voltage input and output.
• Connect the voltage regulator and battery, check whether the regulator and the battery have
the same voltage input.
• When the generator operates normally, the carbon brush should have approximately 70
volts.
Measuring method:
• Use the multi-meter 20V DC to measure the voltage of battery, voltage regulator input.
• Use the multi-meter 200V DC to measure the voltage of the carbon brush.
Repair method:
• When the voltage regulator has input but no output, there may be two possible reasons, (output short
circuit protection, secondary winding protection). Cut power, discharge regulator and reconnect. The
common protection time is 90 seconds, but under abnormal condition it will need about 1 hour.
