You can use a multimeter to check for continuity between the frame and each output terminal of every speed controller with the power off. You will likely find a short on one of them if this is related only to driving. It is normal for motors to have some resistance (2k-10k) to frame as the brush dust builds up inside. It is not normal to have a reading under 100 ohms. I am thinking you are going to find a shorted wire(s) in one of those outputs. There are two things that are known shutdown issues for the cRio. That is the cRio tied to the frame with another path somewhere, or a simple short on the output of a controller. If you are using Jags, the short should show up as a fault on the Jag that is affected even without motion I think.
So the output from the vector to the CIM motors? we are running 4 CIM motors as well. So we need to put the hot wire to the output and the ground on the multimeter to the frame and if we get a reading of 100 ohms we need to replace the motor controller? or is it the wire from the PD board to the Vector? Thank you so much for your help!
