Is anybody familiar with this set up? Does the original cable have a similar end on hot too ?? Where can I purchase this complete terminal set. I have attached a photo of the wire. Note the fuse hanging out of the white cable with black end. Any info anyone has for me would be appreciated. Thanks alot
If some PO has not buggered up the wiring too much red should be positive. White may go to the negative terminal and it would make sense a 50 amp fuse is on the negative line to disconnect the battery if there is a serious dead short somewhere so you don't burn up the trailer. There may be a separate ground coming out of the Univolt. You should be able to get new terminals from auto parts.
If you have not yet considered it, get rid of the Univolt and get a 3 stage converter, you can reuse the Univolt fuse panel if you want to.
