Yesterday i was putting the battery back into the trailer after it being in my shop for a few months due to the weather. As I was doing this I noticed that there were a few sparks while I was adjusting the cables onto the battery posts. I went in side to check things out. The fridge light comes on when I open the door, but I cannot turn turn the fridge on at all. The radio will not come on either. The monitor panel for the tanks and battery does not light up. I thought that I might have blown a fuse. I checked them out and could not find anything blown. Did I blow something that I do not know about? Any of you in TDR land have this problem? I really don't want to take it to the dealer for them to charge me major bucks just to look at it.
