I was told (second hand) that we were told it indicated a short somewhere. It's late and has been a long week at work, but I am currently failing to see the logic that it indicates a short.
Any thoughts? Anything I could be missing? I can certainly help try and isolate branches (remove breakers 1 at a time, visually inspect wires and sensors, etc) but 1M is > 10K so I just fail to see how it is a sign of a problem. I am sure someone will enlighten me here though.  |
Make sure your Axis camera and cRIO are electrically isolated from the metal chassis.
Check any Banebot 775 motors for case shorts.
Check any sensors for grounded frames/mounting bolts (Sharp IR range sensors' mounting screws are grounded).
