We just purchased 1984 Pace Arrow and the batteries were disconnected and the former owner cannot remember how to hook them up. It has two aux batteries (have the main battery installed.) Any help?

We need to know what batteries you have.Are they 12 volt or are they 6 volt?

Perhaps you can download a manual for your RV online, or do you have a customer service number to call?

Follow the cables. the one that connects to the frame/ground is the negative cable. The other one is the positive.
If you have two 12Volt batteries, they are connected in parallel.
If you have two 6Volt batteries, they are connected in series.
OBTW, It's not Rocket Science!

The Trojan Battery User Guide has excellent diagrams on battery hook-up for both 6v and 12v configurations.

If your batteries have three (3) caps on top it they are 6V and should be wired in series. If they have six (6) caps on each, then they are 12v and are wired in parallel.

The batteries are 12V Deep Cycle. My husband has them hooked up together in parallel, but we need to know how to hook up the camper wires to them. Thank you for all your responses.
