Nope me either. I got down to floor level, stared at the outlet on the wall and didn't see any power running around in those little slots you plug things into.

in order for the generator to stay running the control board needs to see 90 volts ac otherwise, it shuts the engine off. I typed the last post from my wife's cell phone. it would help to be a little more professional when you reply, it doesn't scare people off. another thing is a 9mme a 1a that is what the tag says on the front of the generator and the shop manual goes through the procedure to check the voltage it is just not clear where the terminals are or where the flash diode is.

I was not being disrespectful when I was asking about what you were working on!
We have ZERO idea what you were asking about in respect to the hundreds of different model of Onan's made so it's generally not possible to answer a question without model and serial numbers.
Plus the extra bandwidth to keep starting new threads on a set you might already have a thread started on it. Just saying.

There is a TON of knowledge here however, they are not mind readers, a little more information was needed. Thanks for posting the model number.

From what you posted, I have no idea of what sort of generator you are talking about. Going to make an assumption that it is an Onan or you would not be posting here. Onan made hundreds of different models and I couldn't begin to guess whch one you might be referring to, what the problem is, what you have done to try to solve it or the results of your work.

Folks here are real nice and go way out of their way to be helpful but you got to help them with basic information so they can help you. Get testy with them and you're on your own.

Look Johnny, Iv'e been on my knees for hours staring at those wall slots looking for the magic juice. Two of my neighbors came over and also were perplexed. I got one of those tester things with the numbers that go all jibbity jibbity and stuck them in the slot things per Goober the guy next door. Think I founsd it. One slot I forget, the bigger or smaller one says 121 volts and the other one nothing when I touch the other wire to the screw on the front. So I think I have half power. Is it normal to have a big flash when I test?

Looks similar what I did when I was small. Except I washed the wall and outlet with a wet sponge checking to see if I would get shocked.........I was.

Edit: My tester was a hairpin spread apart to go into the outlet at my age of two, nuts for electricity ever since. -- Harry
