Is it my imagination, or are many of the strands of the (formerly) black wire broken just above the crimp connector? If so, that's likely the cause of the problem—assuming things didn't get hot enough to melt or at least greatly weaken the copper, which seems probable to me. (Copper melts at a bit over 1000°C, though as is typical for metals it gets a lot weaker as it approaches the melting point.)
/\ This... some of the wire looks severed just outside of the crimp, perhaps flex failure due to ocillation while traveling. Is there enough excess length or was it wired pretty taut at the other last fastening point that the weight of the wire would cause it to strain at the crimp from too much tension, not relaxed enough?
