Well, maybe that's true, but we've seen a number of rear grounds go bad. Time/temp/moisture/disimilar metals/electrolytic chemicals are all factors in corrosion. Dcrasta is keying in on the temperature. Interesting.

All that noted, this is really the first time I've noticed somebody has implicated that front stranded cable, outside of cleaning its ends.

I'm going to replace a couple and see if I can detect changes. It would be interesting to replace the cable and see less variability in voltage meter, for instance.

Or better yet the tach. I've got two that are intermittent.
