Onan 2500 lp generator
I have a 2019 arctic fox with an onan 2500 lp generator. I'm having a starting issue. It started with rapid clicking, like a car solenoid at low voltage. I checked voltage at the two cables leading in at the back and got better than 12 volts. I removed the brass washers and cleaned them anyways. Same issue, and when it would turn over I noticed an arc here and there. I removed the unit from its home and got the housing off. I checked all connections for a loose wire or something obvious.
When I turned it over, I noticed arcing and sparking and realized it was at places where there was metal to metal contact, like where the exhaust heat shroud meets the bottom of the generator tray, only noticeable when the cover was off.
Anyways, I think I have some sort of short going on, and to add to that, I installed two batteries and this problem might be something I did when I put the new batteries in. I have no block where the majority of wiring goes, just a cluster, which I will deal with later
I tried to remove one ground at a time at the battery but it turned over with all negative wires off, so I'm really confused. I don't think it's a mechanical issue, but the arcing is not cool and im about at my limit of knowledge with 12 volt.
I'm contemplating removing the two leads coming into the back of the generator and straight jumping it off of a battery to see if it's a wiring issue, but don't want to screw anything up unknowingly. Any suggestions?
