Onan ignnition parts?

[onanparts.com]

Cummins started to buy Onan in 1986 and completed the purchase in 1992. In 2008 they merged the two names, CumminsOnan. The parts problem I believe is due to several things. Since the Onan engines are no longer on the sales floor powering new tractors, welders etc. The dealers wrongly assume parts are no longer available. Or they are just LAZY and don't want to bother supporting the enormous number of machines still on the job.

I plan on starting a new thread here at Tractorbynet with a listing of the most common Onan part numbers and their availability. Now I just have to go and do it.

I have an Onan Performer 18 XSL with what I think is a failing ignition module. I've checked all the obvious stuff (safty switches, grounds, etc). It's not a fuel problem. It starts and runs well but cuts off when it warms up. As soon as it's cool it will start again. Cuts off just like I turned the switch off. Does anyone have any idea where I can get a replacement module???? I have not been able to find one. I can not read the serial number of the engine. Any help would be appreciated!!

Here is the best place to buy that Module:

I would check the wiring connections first. I'm talking about the big one on top of the motor. Mine was the problem. Not the ignition parts. The spade lug connectors were loose "mechanically" causing the ignition module to loose power intermittently. Was a simple fix to just rebend the spades to make a good connection again. Did that in February on my Performer 20G in my Steiner and it's worked fine since.

Are you a dealer in Onan parts? If so, you might want to mention something at the various forums - I've seen some posts about guys looking for Onan parts in the Lawnmower/Small Engine forum over at BITOG...

If it starts and runs until it gets hot it could also be the ignition key switch.. I had a bolens G16 that would run for for about 10 minutes and then die just like that, and wouldn't start until it cooled.. Turned out the key switch was shorting the kill circuit to ground after it got a little warm..

Any ideas what would cause one to spark ONLY when the starter is NOT engaged?

Just in case you haven't found an ignition module yet all you need is to go to the Toro web site and click on parts, enter your model number and no serial number is needed. You can get the part number but you have to get the part through a dealer or aftermarket dealer like Parts Tree and others.

Actually there is one on Ebay right now. Enter wheel horse 520h in the search box. 516,518 and 520 are the same I believe.

I had that same problem with a 520H and that is what it was. After looking at a lot of websites it seems to be a common problem.

You do know you have to remove the flywheel shroud, the intake covers, the coil, the flywheel, governor link and a few other things I can't recall at the moment to replace the module?

i gave up on onan engines years ago: when a machine shop quoted me more than the cost of a new motor, to rebuild my 16hp 2cyl....they said the parts were really high..?

I rebuilt a couple CCK's about 20 years ago. The round main bearing (think regular cam bearing for auto engine) cost $50. for one!!! The gasket set cost more than one for a small block Chevy!
I don't know how Onan EVER stayed in business.

I'm not he, but if you click on his name and go to his home page you'll find he is a dealer. He probably doesn't want to anger anyone by broadcasting the fact he is a dealer in every thread, there are people who take offense at that.

I have read you can replace the coil with a gm dual plug coil module. Probably would work as both the plugs fire at the same time and it would have a higher voltage spark I bet.
