Customer Question

we have a 2010 keystone 21 ft raptor toyhauler and are having trouble getting batteries hooked back up after taking them out for winter storeage.
Our battery box is small and hold two marine batteries there are four connectors in this box when looking into box from outside two lines come from the left, one wrapped with red tape and a shorter on with black tape on end. from the right side there is a short black wire and one longer white wire. Can you tell us out of the four wires mentioned what is positive and negative. it looks like one positive (red) two negative (black) and one ground (white ) It doesnt work that way?? We also have one red and one black wire that are free not inside the box or attached to camper in anyway, which we assume are used to bridge the two batteries to work together.

ok
This might be a bit confusing. Keystone likes to use black for positive and white for ground, however the jumper wires that tie the batteries together will not matter what color they are but I would hook black as the negative jumper and red as the positive. So the incoming to the battery, follow the black cables and see if they are going to a fuse or breaker, this would confirm positive, the white see if it is going to the frame that would be negative, kind of confusing but if you follow the cables you should be able to tell, if a breaker or fuse is in-line, positive, if it is going to the frame negative.
