We've gone through code to ensure we've got the correct PWM Channels being assigned, however we can't probe any of the WPI Libraries deeper (it just won't let us).

As far as hardware, ensure that the Victor and Digital Sidecar are getting power. It's difficult to use a multimeter and see what the readings of the actual PWM cables are but we've tried and it seems as though it's not putting out any power (signal) through the cables.


Other debugging steps have included trying different PWM Channels and PWM Cables, we have yet to try different Victors, but it doesn't seem like a Victor issue.
