Short in the circuit or the circuit was overloaded.
there is not a proper grounding wire mounted to the body of the car or truck.
Something is shorted to ground on that circuit
No, Plastic is not conductive! I other words plastic can not conduct electricity therefore it can not produce resistance, and resistance is what you need to produce heat. and that heat would melt the plastic. Now if you touch a "live" wire to metal and that metal was grounded ( for example to a cold water pipe) then you would be completing the circuit, then that piece of metal would heat up very rapidly and eventually melt! of-course the smart person would not do this but if you where not so smart be prepared to get burned!!!! BE SMART!!
Moisture causing corrosion on the nutted wires causing a high resistance on the splice which in turn creates heat. Sometimes on conditions like this the wire insulation can melt back up to six inches. Close to the splice the insulation can actually get so brittle that it will fall off of the wire.
A positive wire is grounded out to the frame someplace on the car. Best take it to someone else to get it fixed.
You melt the metal and pour it into a thin mold the size of the wire you want.
Yes. They melt it down and recycle it.
Fusing current for a wire is the current at which the wire will act like a fuse (melt).
The wire gauze provides a barrier between the ice and direct heat, preventing efficient heat transfer to melt the ice completely. Instead, the heat is dispersed more evenly across the surface of the ice, causing it to melt slowly. This phenomenon is due to the wire gauze acting as a thermal insulator.
A fuse.
That may be because there may be a virus or there can be a problem with the C.P.U wire.
The wire may not melt and break if an unsafe current is produced.
