    Vehicle Tyre Compressor wired direct from battery to pump. Wire overheats.

    I just bought a 12 volt tyre compressor and the instructions say connect it directly from the battery. The pump worked well but when I disconnected it the wires were very hot. Does this mean that the wire is not sufficiently robust?
