It is probably a wire burnt off of the last working plug or the first not
working plug in the circuit. If the plugs are quick plugged(pushed in the
holes instead of wrapped around the screws) this causes the wires to have a
poor connection after a couple of years, especially if there is a heavy load
at the far end of the circuit.
