The wires connecting to the VSC need to be zip tied together and then zipped to the nearest secure point to completely prevent the wires from vibrating.
Good Call.

Yeah, a poor connection is basically a bottle-neck in the electrical circuit. Electricity flowing through circuits, is a lot like water flowing through pipes.
Try to picture, say, 20 amps of power flowing "freely" (cool, temp wise), down a 10G wire. Say that wire turns into a thinner 20G wire, and back into a 10G wire.
Basically, all of those 20 amps need to squeeze down and fit through that 20G section of wire at the same speed it was travelling through the 10G section. (speed of light, FWIW). All of the "compressing" of energy results in heat. It's very similar to how compressed air gets hotter.
Using 'too thin' wiring results in heat because you're accessory is trying to pull more energy than the wire is capable of easily flowing.

Update: I had to do a quick fix and just crimp new wires in where they were melted. It runs fine now and Flex a lite will be getting a request for a new VSC 
However, I will be rewiring it and using zip ties to keep the wires secure. I may even solder the connections on there so it doesn't come loose again.
