Now he left this with power on continuously then he may have fried the coil.
I send you a link to the service manual that is on my G drive via PM.
I don't know how long he left the power on the negative terminal...I assume for a bit seeing as you would have had to tighten the nut for it and he tried to start it after that with absolutely no spark at all. He then changed the wire back to positive side and no spark then either! And, I looked at the wiring...he has the power from the positive side of the solenoid to the positive side of the coil. So, the negative side of the coil certainly would have gotten quite a jolt from a fresh battery I would think!?
I ordered a new coil but it looks different than the one on the generator...Onan 166-0772 Ignition Coil.
Actually, I haven't ordered the coil yet...KE4AVB, thank you for the manual! I'm going to check the coil for resistance first...
