When you are issuing a "full throttle" (forward) PWM command, you should have a duty cycle of approx 20% (2ms pulse divided by 10ms period). So your multimeter should read roughly 1 volt across the white (SIG) and black (return) PWM wires. Use the DC setting and observe proper polarity.

Sorry for wasting all of your time. Turns out after we had it semi-working our first solution was to pull out the cables and we reversed them and didn't put them onto the sidecar the correct way.

So I switched them out and with the robot enabled, I put in the wires into the victor myself, and it's good to go.


Sooooooooooooooooooooo...yeah.....woops.

Thanks for your help, in pretending my insanity was sanity.

Yup...I removed all the PWMs and checked them, it's giving a 0.75 volt reading in neutral. So it's working correctly.
