A short in wiring any where should blow a fuse, not melt your fuse panel. My guess is the problem was/is in the fuse panel. Possibly loose and/or bad connections creating heat there. A year or so after purchasing ours I checked my fuse panel and breaker panel and found multiple loose connections in both the 12 vdc and the 120 vac connections.

The equation for power in watts is the current squared times the resistance the current is flowing thru. If you had 10 amps flowing thru even only half an ohm of resistance in a bad connection, that would be 10 squared times .5 = 50 watts. Think how hot a 50 watt light bulb would get.

I probably need to check mine again as it has been a few years.
