Are your Jaguars on PWM or CAN? If the former, verify that power supplies are in place and solidly connected, and take a second look at the DSC LEDs. If the latter, and you're using the serial interface, check your serial-to-CAN converter (we managed to somehow snap two of the solder connections in competition).

Do you have any diagnostic tools that can replace components of the system? (e.g. serial-to-CAN tethering for the Jaguars, a servo signal generator for PWM control, a 'scope to check outputs) If so, do take a shot at using them to try to isolate the problem.

I know that you can access the cRIO via FTP and look around for your code, but a forum search would yield better instructions than I can provide.

Hope this helps.
