Bill,
I'm afraid I completely don't understand what you're trying to do with the relay. If the relay is supposed to energize the Minarik board, then it needs to be switching the "Hot" leg (black wire) of the AC input to the Minarik board. You appear to have it connected to both the motor terminals and one AC terminal, which is wrong. If you connect the motor to the Minarik, and connect the AC line directly to the Minarik, put the jumper in the "manual" position, with the potentiometer installed, the motor should spin. If it doesn't, then I'm afriad your Minarik is toast.
Regards,
