Curious, never seen this before - what would cause the wire sheathing distortion like this at the connections? Bad connection/crimp on that side and overheating? TIA.
I agree it looks like overheating from a poor connection. Could be that the connector corroded over time. Nice find. :sunglasses,
Overheating at the splice. More corrosion leads to more resistance to more to more heat and more corrosion …
Did you have a question, Mike?
Edit: I didn’t see the pic.
