I have a 10ft Dutchman Tent Camper, it has a Centurion CS 1200 Power Converter. This year when I hooked the battery up, I reversed the wires for a second and now it blows fuses everytime I hook it up the right way. I believe I 'blew it'. Looking for any solutions. Buy new? Fix it? Brands? Where to purchase? Help Thanks in advance to anyone that can help.
