Hi Gene, Well, it's a little tricky because of the amount of cables I have running next to the ones of the spindle. But I checked the integrity of the cable and by visual inspection it all looks alright. It's a 3 wire cable with the black insulating cover so it's pretty well protected.
I really doubt the cable is the problem from what I've experienced and from the condition of the cable in general.
