Can you ID this alternator?

Well you still have not explained anything. Which regulator are you using? If you replace this one with a like one, you need to ground one field IF you are using the older regulator. IF you are using the 70/ later regulator you need BOTH field terminals functional and you need to be sure the "new" on does not have one field GROUNDED. THAT is a common problem with rebuilts Just ask for one for "about" a 73/ later vehicle. I would not get anything more than 50-55 A if you have not upgraded the factory wiring.

It’s a 1967 barracuda with a 1970 318 installed. The wiring in the car is original. I think I found my problem. When the car is running, I took readings at my old style voltage regulator. I have ~11v at the IGN terminal and only ~2v at the FLD terminal. Safe to say the VR is faulty? The car is simply running off the battery at this point.
