3NE-300 with Fanuc 5t issues

$

I have a new (to me) 1979 Hitachi Seiki 3NE-300 with a Fanuc 5t control. The machine was working before it was moved 20 miles to a new shop. All voltages are correct on the boards and taps for the transformer. The phase is going the correct way (clockwise). The problem is the machine will not become ready (ready LED is not lit) and turn on the power to the servos / spindle drive (MCC). I have 24 volts on the PRDY1 and 0 on PRDY2. There are no alarms. I am at a loss on what to check next as I have no circuit diagrams and very little info on this machine. Any help is sure appreciated.

Thanks,
Wes
