Troubleshooting alternator

I’m hoping the forum can help me determine that I have made some obvious newbie mistake and not that I need to replace my old model Motorola alternator. We are testing this new to us ‘67 A4 after having replaced and rewired the whole thing. So far this is what I’ve got:

1. Wiring the ‘clip connection’ from the regulator to the pos terminal on the coil
2. Connecting the output terminal to the pos on the starter solenoid (and this right back to the pos battery bank
3. Wiring the ‘clip connection’ on the regulator to nothing and taking the output of the regulator off the alternator (is this the exc post?) and wiring it directly to the pos on the coil

None of these scenarios create any voltage increase when we turn the engine on. We are on the hard right now so running the engine with water spraying the cutlass bearing and raw water from a bucket by not for too long at a time. We are testing at high idle.

I understand that a lot has been written on this subject and I think I’ve read most, but any suggestions would be greatly appreciated.

Thanks!

Siobhan
