65 Barracuda - No Charge from Alternator

No it grounds thru the block. Do you have power to the field wire at the altenator when it’s running? I’m guessing you don’t.
I just started the car up and when touching the field terminal on alternator it showes 3 Volts on it. I can see those same volts on the VR and then I test the opposite side of the VR it varies between 3 volts and 11.5 Volts.
