I know this is a beat to death subject and I've searched, but I wanted some input on the conclusion that I've come to.

Basically it's running off battery power only, no alt output to battery. I pulled the pos cable from battery while it was running last night (I know) and it died immediately.
Quick run-down: replaced cables (battery to starter, alt to pdc, pdc to battery), replaced/cleaned battery terminals, cleaned all grounds I could find, replaced battery (before I realized it wasn't charging). I have also pulled the alt and had it tested at O'Reilly's and they say it's good. The only thing I haven't done yet is to test the "field" terminals on the back of the alt.
After a couple of hours of reading this morning all indications are that either the alternator or the voltage regulator which apparently is in the alt are bad. So, since I know it's possible, how probable is it that the test at O'Reilly's was wrong? Could the alt pass that test while the voltage regulator is bad? The guy asked me if the vehicle had an external voltage regulator which I wasn't sure of at the time and suggested that might be the problem, but since it's in the alt that he tested what now?
This is my wife's dd and she's not happy having to shut off the AC in order to make it home when it's 100* outside!!! lol
Thanks in advance!!!!
