Went back down with some parts, finished some things up and started looking at others. One of the things that was worrying me, is that there was no power to the coach itself unless you ran the generator. Back down with a tester today, no power at the fuse panel for the coach. Go outside to the batteries that are brand new and I noticed that they are all wired in series, giving 24 V total. Then I noticed that there’s only one cable hooked up to the batteries. And yes there is the positive hanging in midair. I hate stupid people.
