Testing for Continuity of the Gray Cable on a StairMaster 4000PT
- First, disconnect the grey cable from the back of the console and UNPLUG YOUR MACHINE from the wall.
- If your cable has a 6-pin round connector, you will need to check pin sockets #5 (black wire), #3 (blue wire), #2 (brown wire), and #4 (white wire) with your ohmmeter for continuity in each pin. Should get continuity from all if the cable is good.
If your cable is a 9-pin cable, you will need to check pin sockets #5 (blue wire), #3 (black wire), #2 (brown wire), and #4 (white wire) with your ohmmeter for continuity in each pin. Should get continuity from all if the cable is good.
