Sorry I wasn't very clear on that first one. So for the motor, there is continuity between all three phases and high resistance between the ground and phases of the motor. This is good.
For the Board, without 54.6 VDC on the High voltage line, I am getting 0.33 VAC from the 6 gates to GND. With the HV on at 54.6 VDC, it is 2.7 VAC on all the gates and to the 3 phases? None of this is changing with throttle action. This is normal?
I probably couldn't get the motor to do anything anyway as I am trying to make a siemens PMAC 1FV5139 do something. Motor is not hooked up for this instance.

Thanks for all the help!
