Well apparently I have 2 voltage regulators, but this one is set up as a 3 wire and not a 1 wire + ground... Hhhmmmm... I've also done the AC/DC (great band) test this morning and.... *ding, ding ding* we have a winner!!! It is producing AC voltage and DC voltage...so a new Alternator should fix my problem in the end... I'm going to see later if Napa is open and Just nab a standard/ New 60(ish) amp, 10si. We will see if that fixes the issue. Again thank all of you for the help.

Follow up... I just learned the difference between a 10si and a 10dn...i have a 10dn with a 3 wire hook up... So there is that. Doesn't change the fact it is putting out AC and DC voltage indicating a bad diode(s).

Learned more... My alternator has connections on the top (10si) and not the back (10dn) so further digging is needed on my part to see of someone else did or half did a conversation *shrugs*
