I am going through this right now. I had the dreaded code 36 shut down last year, changed the fuel filter and it ran for 3 hours and quit again.
Sometimes runs for hours, other times seconds or minutes.
FOR sure, the fuel valve is shutting the gen down. It runs perfectly till it shuts off and issues code 36.
When it shuts down, does not get sick, stumble or change tone any at all, it just kills power to the fuel valve and pump and quits. I can immediately restart with zero difficulty and it might run another hour, or 10 seconds and quit again.
Pulled the computer which is potted so no chance of investigating any capacitors or circuits.
All plug connections are clean and corrosion free.
Something is either telling it to shut down or the computer is wigging out, it is not a fuel supply issue, that has been confirmed also.
Makes no difference, hot, cold, under load, or main breaker off and just running, full fuel, half fuel, remote start hooked up or disconnected.
Good A+ and Grounds.
AC voltage output is steady as is frequency, till it shuts down then of course it all goes down together.
Anyone know where to send a controller out for testing or have ideas?
