You are correct. You have the big frame high output 105-120?? whatever amp alternator, and they do indeed have a separate ground stud. That one appears to have been hot? Might want to mentally note to replace later.

Its already on the list solely because it throws belts and weighs a ton

About relays: You can buy what has become known as a "Bosch" style relay at any parts store, but they may not KNOW that's what they have.

But I would not get sidetracked until you get this cleaned up some. I would do following: Get the module mounted, and get the distributor pickup wire cleaned up, shortened if possible, and TWISTED. DRESS the distributor wire along the firewall which adds some SHIELDING affect, rather than dangling it out into thin air

Um, you have seen the several times where i posted that the wiring looks this way because of testing? I get the feeling you've missed that.

Get the battery charged up, and power the thing with a nice big clip lead direct from coil+ to the starter relay stud.

THEN deal with low voltage, which is probably a bulkhead connector/ ignition switch problem.

Google "Bosch relay wiring"

and you'll soon find that many (most?) of the aftermarket accessory relays AS WELL AS the ones found in modern underhood relay boxes are in fact "Bosch" relays





AND NAPA/ O'Reallys also should have a mounting socket/ pigtail to fit them to

Here's one with a mounting ear on the relay and the socket/ pigtail:
