Luke Walling wrote on Sun, 15 October 2017 18:34Hi All,
I've begun working on the 78.
Now that I've replaced the 7 year old golf cart batteries I am starting to work on the electrics. The generator turns over smooth as silk and has what looks like fresh fluids in it. It doesn't get fuel, and has a little aftermarket fuel shutoff valve inline. The prior owner reports it ran though I suspect this is 4-6 years ago.
I've friction fed it fuel, and it certainly feeds it in. But.. alas, no fire. Checked plugs (which don't look too used, just a bit of carbon on their tips).
I do notice a module with wires removed that look to have been hooked up and leading back towards the ignition system and motherboard.
Any tips on if this could be the cause, where to start? <snip the picture>
Luke,
The disconnected module is a charging voltage regulator that you do not need as the converter should be charging the house bank when the Onan is running.
Did you do the jumper 5 to 9 and check for fuel delivery?
Also, the spark - at best - is barely visible in daylight. If it still has points, clean them.
