I had to terminate some pre-run data cables soon after my second termination I thought I was going crazy. I then realized that the twists in the cable were reversed. Rather than clockwise it had come off the extruder counter clockwise. Luckily it was only six locations, after so many years untwisting pairs counter clockwise you realize how accustomed we are to doing things in a particular way.

Check the cable and it was some no name manufacturer. Anyone else run into this.
