    I spent all my time turning wrenches and know nothing about wires so be patient with me please.

    I am replacing a water heater in my motor home and the wires that come from the 12v battery source do not match the standard colors. I have an orange, a pink and a yellow wire from my RV to connect to my water heater switch.

    My question is using a multi meter (which I am not good at using) how would I determine which is the "+", "-" and ground? Sorry for such an elementry question but I obviously know little to nothing about electricity. Thank you.

    Hello Bluesjunky2,
    You already have a thread/topic started on this question, here:

    Starting multiple threads/topics on the same question creates confusion, which is why it is frowned upon. Expect a Moderator to close this thread. Replies are already in the other thread which you started earlier.
