<VV> help! Charging system dead!

[Ray Rodriguez III]

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,
