Not to de-rail this topic again too much, but I wanted to add an update. After further investigation, the wiring was not at fault at all. We do not use 'cannibalized PWM y-cables', but actually create our own out of bulk PWM wire. The wiring was stressed a bit, but not defective or faulty. The digital pots, however, were where the problem was. Both the elbow and the shoulder pots are the MA2s from usdigital.com, and both died, either due to static shock or strong magnetic field too near them (as they work off change in magnetic fields to determine rotation). We are still investigating the root cause.
Either way, we are fixed, and ready to rumble at IRI now
