No alternator output?

Hi all. I just had a period correct alternator ( Autolite alternator Type 2A, 60 amp output) completely rebuilt/restored, and I am using a new Autolite regulator (reproduction from NPD, C5AF-10316-A with Silver markings).

I installed these components and have no charging. My Red ignition light stays on all the time and I have no movement on my Lucas 50 - 0 - 50 Ammeter gauge with the engine running. Also a voltage check at the battery shows only 12 volts, not the 14 volts expected while charging.

My wiring is shown in this pic:

Can anyone suggest a quck and easy trouble shooting process to determine where I've gone wrong?

Thanks
Greg
