We picked up our 2003 American Eagle on Wednesday and drove it home; arriving today. This post will concentrate on the genset.

Turned it ON in hopes of getting the A/C to work in this 90 degree heat. Genset ran a minute and stopped. Did that 6 times.

Call to seller: He might have started the genset while on an incline and with low fuel, so I sucked air. Try starting it again and again. Uh, OK.

Finally is started and ran for 10 minutes. I turned the AC ON and it ran about 10 minutes before stopping. Tried it again, same result.

From what I know so far, anybody care to guess about what to do first...or next?

First thing, get it serviced, oil, filter, fuel filter, air filter. The make sure you have at least a half tank of fuel. They won't run if fuel is near or less than 1/4 tank.

I guess it's an Onan diesel? Check the owners manual, when my Onan gave me trouble it would shut down and send a "blink code" . The blink was on the start button on the gen. housing. There are secondary codes and a procedure to get them in the manual. They will help point the the trouble.
Good luck

First thing I would do is get it serviced. There are a few sensors on there that will shut it down like low on oil. I would do a full service including antifreeze. Check the blinks on the switch then look in owners manual for fault code based on your manual.

When the Onan 7500 shuts down for any reason, it blinks a code on the light behind the start switch. It's probably a code 3, which means there is a secondary code to display. Push stop and record the blinks. That will tell yu more about why it stopped. See your Onan manual, or download one if you did not get it with the coach.

Low oil pressure or inadequate cooling come readily to mind when it stops after running ok for 10 minutes or so. The Onan senses both of those conditions, as well as many others.

The genset slide doesn't work. Somebody re-did some wiring on the coach and spliced the driver's seat and genset slide onto the same source. Since the driver's seat is a 30A fuse, can I assume that the genset slide is also 30A? NOTE: there isn't a fuse for genset slide in the panel under the step....should there be?

A lot of the genset slides are air activated. Are you sure yours is electric??

2003 American Coach gen slide is electric over hydraulic 12volt. The fuse should be a inline located at the pump located in the front most compartment on the drivers side.
