Battery hook up

What yr/model Mallard to do you have? I have a 91 Mallard Sprinter and might have the diagram you need in my tech manual. If not, maybe I can take a couple of pics. As I recall, that white wire comes from your battery charger/power converter and is connected to the battery neg on the house battery.

My configuration was 1 house bat and one start bat. I recently upgraded to 4 6volts so my config might look a little different.

Hi. I have a old Mallard motorhome and starting to retore it. There is one house battery and two deep cycle batteries. Diagrahm is lost of the proper placement of wiring. Help! House battery has pos wire to starter solenoid. Neg wire to ground. Deep cycle #1 has neg to ground and pos to generator. Deep cycle #2 has neg to (booster?) solenoid on fire wall. Nothing on pos side. I have three wires I don't know about. One is a white wire which comes in through the firewall with the large generator wire. The other two are connected. One is red and the other is black. My thoughts are that the red connects to the other side of the booster solenoid down to the pos side of deep cycle battery #2 and then the black (again which is connected to the red) onto a ground. Thanks for any help.
