battery wires - what's positive what's negative

[adwizard]

Hi, I own a 1992 Jayco 1006 pop up camper. I have two questions: It came with the wires all ready for hook up to a battery. One wire color is white, the other is black. Question 1. Which wire goes to which battery terminal? 2. And question two, once properly connected, is there anything I need to do (flip a switch somewhere?) to tell my pop up that I'm working off of 12V? Thanks - I appreciate everyone's input.

White should be negative and black positive.
I would check continuity for white against frame to double check.

No switch to use 12V

The black wire should be the hot wire but I agree with Doug check the continuity from white wire to ground.

Use an ohm meter to determine which goes to ground. The other one is positive.

There is nothing sacred about the wire colors in an rv.

I agree with all the above.
Factory wiring would have been BLACK= positive, WHITE= negative.

Still, best to determine which is the negative with a continuity meter.
