More info: I've been researching since I posted this.
I see that there are more electronics below the "fuse board", that I forgot about. I guess I was exhausted, and it was getting dark too.
So I guess I'll go back to the camper and inspect those boards below. That may be where I see burn marks or something.
The "good" news is that I can replace it with a Boondocker board, without having to replace the whole thing, for a reasonable price, and reasonably easy. I just want to get this thing running again and get whatever money I can get to my attorney.
