I have gone over and over the diagrams and think I have it this time, but I am still a bit nervous. Thanks for your encouragement. The designer, Sergey Kabashian, KSI Labs, has all of the ground wires routed to one station on the machine directly from the drives, brk board, power supply, both 12 vdc and 140 vdc, which I didn't have originally, but I have rewired it to specs. I guess he wanted continuity from the source without any chance of an open. Had I have done that in the first place, I probably wouldn't have mis-wired it. Bob.
