John sent me the carcass and we've had a chance to peek inside the failure . . . Emacs! 95% of the strands failed right outside the crimp . . . a telltale for insufficient insulation support like that offered by PIDG style terminals. A cross-section of the wire grip . . . Emacs! . . . showed good crush . . . no voids. I'm pretty sure that a piece of that extra stiff, two-walled heat-shrink over this assembly would have produced a better story.
