Re: powr dist. board/cRIO puzzle - please advise!

Steve,
You need to check everything following the breaker that feeds the window motor. You could have a bad speed controller, intermittent connection at the input or output of the controller or the motor itself. In some cases, a short in any of the input wiring to the frame of the robot can find it's way back to the Crio especially during hard robot frame hits. In some cases this causes a Crio reboot. You know how long that can take. You also may lose handshake with the wireless adapter. Could you see the RSL and can you tell us what the flash rate was during the outage?
The most sensitive wiring that could cause these faults are power wiring to the Crio, loose hardware on a controller, power wiring on the window motor, and power wiring on the DSC. I am going to bet that the two input connections on a speed controller are very close together. These touch with robot movements.
