Latest saga. Opened up the transfer switch, everything looked O.k., no burned wires, all connections looked good, tight. Plugged in shore power, transfers fine , all O K. Unplugged shore power, wife starts generator, I was watching transfer switch. 30 seconds in, transfer switch relays start chattering, generator dies. Ahah, I thought. Bad transfer switch ! I had a brand new Progressive industries 50amp transfer switch, so 3 hours later, new transfer switch installed. Started gen, same result !! I now believe the old esco transfer switch was fine, and I think the generator is failing somehow. I am now way out of my pay grade ! I still have an appointment with Cummins on Thursday, so am hoping its something simple. Ya right !

Had a similar issue with my generator, turned out to be trash in my carburetor. Not a difficult fix to remove and clean.

Generator fault

Iíve had this happen about a year ago - it turned out to be the air filter

Just went through the same scenario as Ray and my 7.5 Onan diesel gen was shutting down because of overheating. It had not been looked at since installed in 2005 and the cause was no cooling due to the single belt having broken. The manual suggests replacing belt every 3 years but a Cummins/Onan rep suggested to keep using the Gen until belt broke due to the cost of dropping Gen from our 2006 Winnie Journey. Problem is I was never able to relate any fault code to the belt and that was a huge difficulty because by the time this happened, I had long forgotten about it (until the local technician enlightened me upon opening the unit) and tried everything I could think of for about 6 months. It was an expensive fix but necessary on many counts as the 12 years since the purchase of the coach had caused a lot of wear and tear on the unit. It now functions like the proverbial top.

Could it be something simple like the fact that the fuel was lower than x level the generator straw could not reach it, so ran a little but starved.

We had one that would quit after the MH fuel tank was lower than 1/2.
RUSTIC is good.
Kudos to those who make Local, State & Federal Parks & Campgrounds possible and to those picking up the slack by Providing Private Campgrounds.

Generator problems

I know this might sound dumb. Have you checked the oil level. If not enough oil will run for a short time then shut down. Don't ask how I found this out.

I had a similar problem with 5 kw when I bought my motorhome. I found ones park plug had fouled a fuel blew by into the oil, unit would start, run for a minute or so, and stop.

I started it again, then shut the 45 amp breaker on the Gen. It continued running no problem for 10 min. I then turned the breaker on and 45 seconds later it dies. It appears the when the transfer switch engages that's when it pukes. Fuel filter ? Also, it starts instantly. New to Onan diesel generators. Jon..
remove metal plate to access the actual radiator and top off with antifreeze. Check the actual radiator cap, the resivore my be full but that doesn't mean the rad is. Let me know how you make out.
