Onan 20K Generator runs constantly in stand by mode

Had electrical storm last night but never lost electricity. Onan started sometime during storm. I can turn it off, but when I set back to stand by, it starts up running again. Anyone know what the problem could be ?

Your remote start wires going into your transfer switch are closed, which means you transfer switch is the problem.

My onan 4.0 generator will not idle and is back fireing while trying to run it will run fine for ten min then starts trying to die and starts back fireing when I try to keep it running

check for a faulty sump oil switch . check for faulty coil ( magneto on the flywheel) as the time it runs suggests that it is breaking down internally.

Our onan generator ran out of gas. we refueled but the generator will not start. i gave it a shoot of starting fluid, the generator fired and run for a second, then died. could it be a cogged fuel filter?...

No, not the filter, you will need to try to prime the carb better then with starting fluid, pour some gasoline down the carb, you may have to do this a few times, but everything will fire back up again once you get the air out of the system

Remove the air cleaner and inside near the throat of the carb is two bolts holding the carb to the intake remove these. Unhook the fuel line and twist the carb to allow the linkages to remove.

Onan 4000 start good runs only ten minutsand shuts down,starts up

First locate the oil pressure switch and see if you can bypass it,then see if it runs. If not check the fuel filter and fuel pump,make sure solonoid for fuel pump is kicking on.
