Well....
I went out last night to "get real" with this thing. I had my iPad out with a ton of YouTube videos, all the manuals from Onan, a flashlight and a beer and I was going to figure out what to do and see how much of a pain it will be to drop the generator, to pull it out, and work on it.
And it fired right up.
I didn't touch any wires, both the house and chassis batteries registered the same voltage as it did on Friday, as well as the whole weekend. I compared them with both being plugged in to 50Amp shore, as well as having that disconnected for a while.
All three methods of starting worked great. No error codes, and it primes right up and jumps on like a champ.
:ugh: Now what?
