There are two ways to confirm the integrity of your work (and the circuit): 1) Just eyeball it and say "yeah, those connections look pretty tight and the wire looks pretty good and nothing looks loose" or 2) Perform a simple voltage drop test.
Hmm - I don't remember this being part of Bob's electrical manual instructions or primer for wiring up and starting the car. I'll see - nothing I like doing better in 95 deg heat and 60% humidity than leaning over a hot engine taking voltage checks.

New ,rebuilt alternator is in place and UPS is showing the wire from ERA to arrive tomorrow. I decided to bit the bullet and un-wrap the harness, pull out the old wire and then install the new one and re-wrap everything. Everything will back to 'As-New" condition then.

Check those alternator hot leads. FWB is pretty much on the same page as I - planning to install a small washer before the terminal and then use a serrated lock washer between the nut and the terminal. I think I'm even going to stick a cut down vacuum cap over the exposed end of the terminal connection just for another precaution.
