My only suggestions are to mod the default code to try slot 6 with a different Digital Module, and to verify the PWM cable connection orientation at both ends.
P.S. Forgot the basic one - is your battery fully charged
Have you opened up your cRIO to clean it out and add the gaskets?
Symptoms show you only seem to be missing PWM communication between the DSC and the Jags.
With the default project only pwm 1 & 2 are live - the other two should cause Jag blink.
With the correct Teleop long-on/short-off blink the System Watchdog isn't coming into play.
P.S. Even Heisenberg was uncertain about electrons...
