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!

Never saw a Mopar regulator like that.
