Hemi Alternator Wiring

Hey all, trying to figure out what I’m doing wrong with my alternator on my Hemi swapped Challenger. I used the old style external regulator and wired my exciter to it and one of the two wires coming from the plug on the alternator. 12 volts when the key is on. Then I wired the output to the battery, but it will not charge while running. Is there something about the new alternators I’m missing? I have a good ground at the regulator. I used the diagram attached in the pictures. Thanks!
