<VV> help! Charging system dead!

This is jogging my memory now- isn't there a fusible link(s) in the system somewhere?  I can't seem to find it off hand thumbing through the shop manual, but I seem to remember reading about them.  

On reverse polarity the generator's diodes would present a short circuit, which would "blow" a fusible link pretty quickly, I'd expect.  Might have even ruined a connection that was marginal.

You should be reading battery voltage to ground at the generator's terminal, with the engine off- if not, there's an open circuit between the generator and the battery, and if the car still runs, then it's between the generator and the terminal block, right next to the battery...

I replaced the alternator with a unit that was working when last used three years ago, no change.  I swapped out the voltage regulator with one I "think" is good and still no change.  My father is doing his best to test the diodes in the alternator I removed... his memory on how to do this is shaky at best but he says it seems ok.

Is one of my "replacement" used parts definitely bad or could the problem be elsewhere?

Thanks again,
