There is a fuse that runs from my (positive side) of my battery to the trailer. Was working just fine, then I moved the trailer to the side of my house and went I plugged it into the house, fuse blew, Unplugged it from the house, fuse blew. Plugged the trailer into by truck, blew the fuse again. I have a surge somewhere and have know idea where to look. I unhooked the positive side and followed the wire and could find no damage to the wire. Any ideas? Would love to take it down to the dealer, but I have no lights cause when I hook it up to my truck it blows the fuse.
