Generator Maintenance Question

Having just purchased a used 2005 Country Coach, the DW and I did a 4 day shakedown/discovery trip. At the first rest area in the Texas heat we attempted to run the Onan 7500 and it soon shutdown. I tried a 2nd time and same result. After going thru the manuals in the CG I found how to check for codes and it turned out to be coolant temperature. I had it checked in Dallas and it appears to be legit. Unfortunately this coach does not have the slide and it has to come from the bottom. I have it scheduled to be removed and taken to Parker Power in Carrolton. The maintenance records show only 17 hours of use in 2 years. I'm planning on a cooling flush, thermostat, belt, hoses and check the valve lash. Anything else that I'm missing? I do not want to drop this thing anymore than absolutely necessary. Thanks in advance.

The 7500 has a brass fitting on the bottom of plastic tank mine split. I would remove the SMALL cover and pull out the filler pipe and check antifreeze it maybe low.

The coolant recovery tank (overflow tank?) was full and cool. After shutdown I could hold my finger in the tank. It appeared to me that no circulation was taking place and suspect stuck thermostat.

While the generator is out, and if it has not already been done, change oil and filter, check air and change the fuel filter. Also while it is out, I would have the generator load tested and check the freq's. Better to have it check now, rather then having to pull it again. With only 17 hours on the set in 2 years, I would also be looking at all of the seals.
Good luck and keep us posted.

I had the same code on my 7500 when trying to start it in a rest area...it was the heat off the pavement activating the temp sensor. Once I got back on the highway, it started right up with never a problem again. I never started the generator again standing still over hot pavement and never had another problem.

I'll definitely ask them to check the loads and the frequency. They specialize in portable power generation. Thanks for the suggestion as that was something I had not added to my list.

Generator Maintenance Question

When mine was dropped I had them change out the oil pressure indicator switch. Think it was a $20 part.

I have a question. Do the Generators pullout so one can work on them? 2001 Fleetwood Storm.

Thanks,
Alan & Terry

Should I also change the coolant temp sensor and are there any others that tend to fail? It's 9 years old and has 1621 hours on the meter.

Unfortunately mine is not on a slide and the front cap is not split so out the bottom is the only option. The coach has to go up quite high I think to get it out. Another 4 to 5 hours labor on top of the maintenance.

When mine was down I had coolant sensor changed along with oil pressure sensor and the thermostat. They ran a complete test on the entire system. Checked belts and hoses. I all ready had changed oil and filter along with fuel filter and air filter.

Mine had to be dropped because the control board went bad.

Change that coolant tank while you have it out. When it cracks, and it will, you have to drop the gen out to get to it. Had to do mine last year.

I had this problem with my 7500QD. The problem is the coolant temp sensor is bad. With age they rot in the tight housing and won't tell the control mod temp is rising or being shorted it says its hot. I was able to fix mine as it was on a slide and i could get the top of the cabinet off. Its a PIA!!!!
If yours has to be dropped out the bottom I would replace EVERYTHING!!
