New to site, new to Mopar overheating issues

Ok so I tested the regulator and it reads close to 12 at the battery and the IGN side with the key on. The FLD does register. The car is dead now and won't start, I'll get it on the charger. I'm thinking it has to be the regulator that's causing it not to charge right? Here's pics of the regulator and how it's wired. Man what a can of worms! Thank you for all of the help!

I can't get the image of the diagram to load, basically the only additional thing wired in now is the carb choke on the IGN side. The fan was wired into the FLD side.
