cRio Constantly Rebooting

[Al Skierkiewicz]

Travis,
A small number of main breakers have a manufacturing defect that makes them intermittent. If you tap the red button and the robot lights flicker, this is likely the cause. Replacing the breaker is the only fix. Other sources of low voltage can be loose connections on the battery terminals. I recommend that a star washer be placed between the terminals before the hardware is inserted. This not only breaks through any surface crud, it also locks the terminals together so that they can't loosen. Any loose connection or crimp in the robot primary wiring can also cause this brown out condition that takes out the Crio and radio power. Although it doesn't occur often, some teams add #6 wire to the provided Anderson plug to extend the distance between battery and PD. This is the one place on the robot that wiring should be kept to minimum length as all robot current flows through this wire.
