I assume you realize that both wires connected to the break away switch are 12 volt
To test the break away switch, connect one switch lead to 12 volt
positive, and the other lead to the positive 12 volt coach wheel brake wire. When the pin is pulled on the switch, the brakes engage.
If one switch wire is connected to 12 volt positive, and the other switch lead in connected to 12 volt negative, a dead short will be created and the wires as well as the switch will burn up.
All the break away switch does is supply power to the brakes. If the trailer brakes work fine when connected to the tow vehicle, and burn up when tested, there's a LOT wrong with the wiring.
Simply rewiring everything should fix it. I had to do that with mine when I got it.
