I find myself needing to unplug and replug the PWM several times to get it to work. Also, make sure that the PWM is pushed in all the way and not resting on a pin that is out of alignment. All of these would cause the victor to not receive a signal from the cRIO and not work.

Hope you get it fixed,

We have tried switching the PWM from the windows motor Victors that aren't working with two of the CIM motor Victors and it is still not ENABLING consistently. Everything seems to be pushed in correctly, and we have, over the course of troubleshooting the problem, unplugged and replugged the PWM dozens of times. We are still getting a "flaky" voltage readout after all of these things.

The "flaky" readout is from the tip of the PWM, not the DS.
