From the old Thread (which has been split three times): "I think I'm getting to the bottom of this...finally."
The newest problem seems to be with the Onan Magna Arc electronic ignition. Symptoms are as follows:
After a successful test run under load for over an hour with a replacement fuel pump. it would not restart after I shut it down.
After checking the fuel pump function, I checked for spark and found no spark.
I hooked up the timing light and started adjusting the ignition module until I had a flash or two on the timing light.
I got lucky and got the adjustment correct and she fired right up.
After resetting the timing and adjusting the carb a little, I put a load (both Duo-Therm AC units)on it and it ran great.
After running it for an hour, I shut it down and it would not restart due to lack of spark again.
This whole scenario repeated it's self a few more times before I finally gave up (for now)
Is anyone here familiar with the Onan electronic ignition who could explain this behavior?
I hate to give up on a reasonably new ignition system, but if this is a problematic system, I'll give up on it and go with the Pertronix system.
