72 Swinger not charging battery

Voltage regulator? is it internal or external? if its original older mopar its on the firewall...
I thought I included this detail but maybe not.

I bought a new VR, and added a ground strap to its chassis from a common ground.

Issue exists with the original VR and the new one, but as I understand it, new VRs are generally crap, so there's no guarantee that the new one works.

I'm gonna buy one of the adjustable ones sold by MadScientistMat once they're available.

I'll **** around with it some more this afternoon.
