roger black treadmill?

during moving my treadmill did not work. the red power light was working but no display screen was on. i unscrewed power switch and found a wire had come loose, i reattached it and treadmill display came on and belt drive started. but on starting workout i noticed that distance clock dosnt go from 00 miles and also pulse clock digets only half showing i.e 7c instead of 70. there is another terminal with no wire attached,and cant find a wire in the frame to attach to it. as anyone a electrical diagram or photo of the power switch wiring from switch to inside frame. many thanks.
