I took the dead battery off of my 2005 Flagstaff tent trailer. The wires got moved and I am not sure which ones are + and which -. Anyone have a wiring diagram?
So can you not see where the wires go?
If not go buy an inexpensive volt ohm meter (your gonna need one anyway with a camper.) If you already have one then select ohms (upside down horse shoe) find a good ground and put the black wire from your ohm meter to it.
then with the red wire touch all four wires individually
two should ohm zero the other two should not.
the two that ohms zero are your grounds.
