Onan 5500 Gold shuts down release of start button
I have an Onan 5500 Gold, 106 hours on it. I had no problems until the way back from FL in March. Unit would shut down after running for a short period of time...say 30 minutes. Eventually it stopped running completely, it starts and runs while holding the start button. When I run the unit and hold start it eventually shuts itís self down giving me a code 4 reading. I can do this from both inside the coach, and on the generator itself.
Had a small engine repair man, clean out the carb, and change the oil. He said the fuel pump was working. He gave up, and said generators are not really his thing.
I also just replaced the coach batteries...thinking that maybe it was a power issue.
Any thoughts on next steps OD diagnosing this generator?
