OK, Just put a brand new sensor wire on it and still don't work. If you spin the shaft to get it going I think it is 3 lights on, if you don't spin the shaft I know it's only 2 lights on. I guess it only fires 2 poles at the same time. With the other Pro4 not HD it works fine and with a RevTech it works fine, What could it be other than a bad sensor on the motor?
