How many volts should I get from the Onan?
No load, roughly 125 volts, but you’ll probably have to do some adjusting to get it right if its been sitting a long time. Need 1800 RPM to produce 60 hertz = 120v. If you have power inside the coach, you can use an electric clock with a second hand and your wrist watch to regulate the RPM’s. Plug in the clock to an outlet and compare the relative positions of the second hands – if the electric clock second hand does not reflect 60 seconds as fast as the wrist watch, your RPM’s are too low and you can speed it up by adjusting the nut on the arm on top of the Onan.
