You either had voltage on the white circuit - possible ignition switch
fault or a brown or purple circuit coming into contact with the white
elsewhere, or voltage on the brown/yellow coming from the alternator -
possible alternator internal diode fault (wouldn't normally go away
again) or internal debris causing a short.
