Battery to RV wiring identification

Question

[img]

[/img]Hi, I'm doing a battery upgrade and moving batteries off tongue of trailer to front storage bay for solar system set up.
Need help identifying a extra 12 gauge wire coming off battery fuse converter tongue connection,daisy chained to another fuse with a 12 gauge wire black/white that disappears under the trailer.
I have a picture, but don't see a way to add to this note.
thanks, Tom

You came to the right place  :)Your slide can have its own pos wire with its neg to the frame, so two pos wires to the battery (plus a third wire for the breakaway)Photos:http://photoposting.is-great.net/?i=2

Could go to a few different places: emergency breakaway brake system (though usually that would be unfused), slide motor as mentioned, propane/CO detector, radio preset memory...

It doesn't seem to me particularly tricky to move/extend the connections without altering the design and needing to figure out what's what. Otherwise, the only real solution is to trace or otherwise sort out what the wire powers, say by disconnecting it from the main battery connections and powering it separately and seeking out what is live.

On a TT the tongue jack is typically wired directly to the battery too.

You battery should have a positive wire for the Trailer, A positive wire for the breakaway switch, and a positive wire for the tong jack. # of ground wires is optional. Can be on the battery or on the frame. It will have at least one.
