This site won't let me post Thor copyrighted diagrams, but you can get them by registering at the Thor website: https://www.thormotorcoach.com/owner-resource/ You need your coach's VIN.

In general there are two batteries wired in series with jumpers: + to +, - to -. Then there is a black negative cable that goes from a + to a nearby chassis ground post. A red cable goes from one of the + to a 50A breaker, through the on/off switch on mine but to a solenoid on yours and then to the converter. Another red cable goes from a + to the battery isolation system, probably the BIRD type for your coach. A third red cable goes from a + to a 100 amp breaker and then to the generator starter.

That is what is shown on the Thor diagram for my 2021 Axis. Yours may be different.

Just wanted to clarify... did you mean "wired in parallel"? "+ to +" and "- to -" is actually parallel... maybe a simple typo?

No typo, just a brain fart . I also noticed that I said the black negative cable goes from + to a chassis ground lug. I should have said it goes from the - terminal to a chassis ground lug.

Too many +s and -s and not enough coffee this morning perhaps.

Your posts about batteries/electrical systems are usually spot on, and I always learn something! So I KNEW something like caffeine was missing!!
