geelmore Report post Posted July 19, 2019 (edited) New (to me) 2005 Damon Challenger has been in the repair shop for a week; the generator (about 400 hours of use) will run for varying lengths of time and then abruptly shut off. When I first got the coach, the generator ran all day with both ACs working. Recently, and the reason it is in for repair, it will run for 2 hours or just 2 minutes; no rhyme or reason for the time lengths and the repair shop is as puzzled as I am. So far, they have changed the oil and filter and replaced the oil temperature plug but it still shuts off at varying intervals.

sstgermain Report post Posted July 19, 2019 We had one that did the same thing and it was the fuel pump. Share this post Link to post Share on other sites
geelmore Report post Posted July 19, 2019 Sounds right but the shop tells me that there is gas in the line every time it shuts off Share this post Link to post Share on other sites
desertdeals69 Report post Posted July 19, 2019 Fuel is quite often the problem. When I was an Onan dealer we would hook up an outboard fuel tank with a hose and primer bulb and straight gas. If the gen would start to die we would hit the primer bulb. It seemed most of the time it would run fine pointing to a problem in the fuel system. Most to the time it was a cracked fuel line. We live in Az so our temps are somewhat warmer than the rest of the country. Share this post Link to post Share on other sites
