They may refuse warranty on a over year old with only 3.5 hours.
I thought a 2007, that's the year of the coach, Purchased New June 2008. I suppose it could be 2005, 2006, or 2007, there is an emission sticker that covers 2005-2007, not sure where I'd find year information otherwise.

I started it and watched for the blinking lights but nothing happened. The Flight Systems trouble shooting guide mentioned that as well, along with some other good information and things to try. Tapped on the oil sending unit while running and that didn't do anything, even jumped it.

made may 2007 first letter of the serial number is the month a=jan b=feb c=march next 2 numbers are the year
if you bought the coach new then warranty starts from that date in june 08
when it shuts down the light on the switch should blink out a code but there may be a short in the remote wires that shuts it down like pressing the switch which may be why you don't get a code.
open the cover and look to the left and unplug the remote wires will be a rectangular plug and it may be in the housing or may have been pulled out the oval hole on the left side toward front of the genset and try to start it and see if it will run
if that doesn't work take it to an onan distributor for warranty repair
I hope it doesn't cost you an arm and a leg to get it fixed. First off, just starting and running your generator isn't going to do much for it. Nothing ruins a generator faster that not running it, and exercising it with a load on it. I'll almost bet, most of the complaints of Onans not working is due to poor maintenance, and not exercising them. All Generators need to be exerciced approx every month or so. Also make sure you use some Gas Treatment if it is a gas generator, and its going to sit for periods of time. If to long, run it until the carb is empty and no gas is left in the Carb for it to gum up. Take care of your generator, and your generator will take care of you for many many years. I do know that parts can and do wear out. But a generator with only 3.5 hours on it, sounds more like it has been neglected. Good Luck. Happy Camping. Dan & Jill

I'll take a look at that and give that a try. I'm going to pull the fuel solenoid as Brodie suggested as see if it's gummed up, I doubt it's the problem as it's always had Sta-Bil, but it's one more thing I can try before taking it in. The FlightSystems guide says the regulator and controllers on this model are buried and require special tools, so I'm almost done with what I can do.

And nothing ruins a forum post faster than someone thinking their opinion contributes to the solution. I really don't see how this is neglect or what 3.5 hours of run time has to do with what appears to be an electrical or electronic failure. It sat for at least a year before I took possession of it, no fuel, no use, sounds like I bought a neglected new generator
If you are the first owner. Warranty does not start until the RV is sold. I would think that warranty would still be in place and Onan should cover it. I agree it sounds like the unit was bad from the start.
Onan makes a fine product and they have an excellent warranty they stand behind.
No you did not abuse it and about the only thing that a genset owner/user can do to contribute to a failed voltage regulator is to shut it down while powering a load.
Yes, Onan recommends running it an hour or so a month with load but it sure as heck doesn't kill them if you don't do it. About the worst that'll happen is a gummed carburetor.
Everyone has an opinion and sometimes, if repeated often enough, some folks think it becomes fact, even some of the real stupid stuff.
it's not hard to replace the controller on your model the controller and regulator are made together.
remove the 10mm bolt under the stat/stop switch to the left of the battery cable bolt
lift the front contaning the breakers and start switch look up in the hole and that black square with the plug in it is the control board
to get it out there are three bolts around the tower it is mounted in one to the left one to the right and one off center to the left in the back.
I would look above the start stop switch on top of the generator end and you will see a black square with 2 wires held in by one 10mm bolt this is the brush block
remove the brush block and make sure the brushes are free to move in the holder and ride in the middle of their slip rings. the 2 brass rings around rotor
if dirt gets in there or you shut the genset down with load it can burn up the brushes
there was a problem with the brushes nor riding centered in the slip rings and they make a shim to realign the end bell
