Overcharging Help needed (74 scamp)

I will check the exact voltages when i get home at everything with my volt meter. stumbled upon a bad conncection at the bulk head for the main hot wire that comes in to the car its hanging on by a thread of wire so going to drill a hole in the bulk head connector and feed some new 10-12 thru the hole . if u jiggle it now the car jut dies( previous hack job by other owners) . Thank u all for the help hopefully i can get this sorted out based on wiring diagrams i have it correct so i think i just couldnt find the blue wire from the ballast around the intake area i needed to make it right right so i thought i could jump onto that wire at the ballast and run it around to the ignition side of the VR and splice those to to the other field side on the alernator.
