Battery Connections

Just making sure, I'm putting my battery back in after the winter. The white is (+) and the black is (-)....right? I'm gonna label it this time.

Not usually. The wire (usually white) from the battery negative post goes to the trailer frame. The wire (usually black) from the positive post goes to the power converter.

Also on the positive post is the wire going to the trailer brake safety switch.

I took a picture of mine before I disconnected for the winter. White is negative and black is positive.

For some strange reason RV manufactures adopted HOUSING color codes for 12vdc wiring rather than automotive.. Personally I think this is STUPID

To make it even dumber, the white battery cable on my Jayco has a red terminal, where the back one has a black terminal. Assuring you will mess it up.

This was exactly correct and the safe way to check. White went to the frame.

Thank you all for your help.

This thread helped me too! Did not take picture of my battery connections prior to winter either and had two white wires I did not remember being there.
