Might be worth opening it up to have a look. If
nothing else, it would eliminate another possibility.

I thought this was already inspected, and cleared.

I don't think corrosion or mechanical failure inside the terminal ends has been investigated sufficiently.

Sure, maybe not. I did take off all the connections, clean the lugs and posts, wiggle everything quite a bit before and after I put them together, but this was awhile ago before the specific comments about the crimps themselves. So, I may not have been thorough enough. I'm going back in there next week.

Bill, these crimps are 25 + years old, please home in on them - run a bypass cable ( one side of a jump set even) and see what happens. I have a back up test cable i use any time i suspect a bad battery to starter or jump post, just because !
