Burl, your breaker/fuse panel should be under your rear dinette seat right next to the sink cabinet. You need a torx bit (#10?) to remove the front panel. There is another panel held with 2 normal screws that surrounds the breakers. Remove that and you will find the buss bars. In addition, under the rear dinette seat (if the cover doesn't lift remove the screws) you will find another buss bar screwed to the floor. That's where I found one loose wire. The ones on the melted bar were too far gone for me to determine if any of those were loose/causing the problem.
