1972 chevy c10 alternator problem

[Yeahsmitty]

I recently purchased a 1972 chevy c10 fleetside longbed truck. I have been having nothing but problems trying to get it to run correctly. I'm trying to tackle a charging/alternator problem. It has a 307ci (not the original) engine in it and has had the wiring converted (not so well) to run an internal voltage regulator. I have tried wiring diagram and wiring diagram with no luck to solving my problem. The alternator gets really hot (not while running) and drains the battery. I am attaching pictures to see if I have something wired incorrectly. I'm stumped.
