First thing is to check oil level as low oil pressure will shut it down.

Probably its similar to the wiring on page 31 of this manual (pdf page 28) of this manual, reference NGK-7000HE: http://www.electricgeneratorsdirect.com/manuals/NGK%20Generator%20Honda%20engine.pdf

Start looking at your safety circuits.

1. High water temp
2. Low Oil
3. Low water etc...

From the manual these are the protection circuits.

• Engine protection: low oil pressure, high engine temperature.
• Genset protection: under/over voltage, overload, battery charger failure, battery voltage out of limits,
under/over frequency, start failure.
• Circuit breaker protection: IV poles.
• Differential protection.


Any one of them will trip the fuel relay closed. What you may be able to do is disconnect one at a time each protection circuit and see when the fuel relay opens. (Make sure to reconnect each one if it had no effect on the fuel solenoid)

Once you isolate which circuit it is in then you can chase wires or change the bad switch.

Thanks for choosing FixYa.

Ground the generated it's self. I had a similar problem after a storm once. First on the generater itself find a flat peice on the frame say by the motor. Sand in down to mettal. Put a self tapper screw in. Now get a 5' to 6' peice of 10 gauge bear copper wire. Attache it to the generator and shove the rest into the ground. Now it's grounded and It took care power surges when I did it. Hopefully this will help you.
