1985 southwind multi battery set up?
Once again I got another question about this thing. Has 3 batterys, 1 main and 2 house. I noticed that theres 2 ways of hooking this up. 1. Solenoid 2. Isolator Now I have never seen some one...

We used to own a 1985 Southwind, bought used in about 1990. It was on a P-30 chassis with the 454 GM, and it was set up like your coach. Two roof airs and a 6500 watt Onan genny. I fought battery problems for several months, installed new batteries, built new cables for them, and still chased gremlins. One Saturday afternoon I made a pitcher of Iced tea and spent the rest of the day on a creeper under that beast.
I tracked down every single grounding wire I could find. The primary one for the 12v system was a stud (memory here), that went to the left frame rail. It was a mess. I don't believe the battery cable running to it was ever properly assembled. I built a new one and soldered the copper lugs on it, then cleaned up and prepped the stud and frame.
Fixing it and then chasing down several other grounds and cleaning them up solved all the problems. It took a day...but it was worth it. You might want to check that out.
Also...for smart isolator/combiner units check out www.hellroaring.com (yes, it is legit) they build some very cool stuff. I have one of their units on our Tournament Ski boat and it has been excellent. I've since installed them on several other boats for friends who are also happy.
