Help with an electrical issue - Battery

New here-
I have a 1999 Newmar Mountainair Model MADP4081 with a Spartan Chasis Model # 2242. I had an employee remove the battery's without marking the placement -or which side is what. I am hoping someone has the same type of Motorhome and can help me out.
I am wanting a picture of how the battery's should be in the "Battery compartment" . If any one can help I would greatly appreciate it -
Are all the wires different- the wires for the Engine vs for the living area?
Is there a difference with the battery cables?
I have 6 battery's in the compartment - any help will be greatly appreciated.

There are two different setups here. You should have two batteries series hd31 12volt used for chassis starting they will be positive to positive then connected to positive leads for chassis. Next you have house it is connected different. You should have 4 6volt u 2200 batteries. These are wired by using a jumper neg/pos to create 12 volt. So with having 4 batteries on house you wire this as 2 sets. I will get you a pic tomorrow. I will post a pic of parallel and series wiring

These two web sites will explain a lot about your 12 VDC systems.

The 12volt Side of Life (Part 1)

The 12volt Side of Life Part 2

So did your employee install everything correctly or do you have a problem?

Or were you just looking for some information on the 12 VDC Battery systems?
