my Onan 5500 in my Voltage went south on me on my last outing. It was working fine then poof... nothing. A check and I could not figure out what was causing one of the breakers on the genset itself to pop. After returning home I called my mobile generator fixit man. He figured a chaffed wire inside the flex chase from the generator to the junction box located in the front. He said it was a common issue with these units. Sure enough, as he pulled all that apart there was a wire worn through shorting out.
Just a heads up. It probably just vibrated against something and made a short to ground but all the electronics on the left had to be removed to get to the wiring. It was about an hour fix and another half hour replacing everything.
