You could test for any leakage resistance from any phase to the spindle frame, preferably this would be done with a high voltage megger, but a VOM will give you some idea.
The 160v you get now could just be normal inductive effect if the frame is presently isolated.
How did you run the ground?
Try removing it temporarily and see if the spindle runs again.
