Ok Jason, got the parts in and began the new install......and found the problem. I could not get the new board to come on period. I left the p/s on and checked voltage at the input and the voltage was 1.8 volts and that was right were the wires from the p/s came in. So I changed p/s turned it on and still no lights. By this time I was freaked because you told me you had tested and all was good.
So, I took the old board with no usb cables hooked to it, applied power and bingo.....main board led lit right up! Now I really am confused. I thought about it and decided to plug each axis into the usb board one at a time. X axis.....green lite......y and z the same results. When I plugged the a axis, which in using the home plug, all the lites went out and the voltage at the input dropped again to 1.8 volts. I had removed the switch end of the usb so I could ohm out the individual conductors so I wondered if the usb plugged into the usb board was bad. Turned everything off then cut each conductor individually just to be safe. I then turned power back on, inserted the usb for the home back into the usb board and got a green and red light on the panel leds. Checked the voltage in and it was at 4.82. So now I take the switch end usb and change it for the one in the usb board, and still have lights!
Now I am assuming.......but I assume that there is a short somewhere in the 4+1 cable that is causing this. If I ohm out again and this time check each wire instead of just the corresponding color wire, will it show me continuity if there is a short?
Mike
ps gonna go test it anyway but hope someone answers
