The Jaguar goes solid yellow when it's receiving a PWM signal that tells it to apply no power to the motor. It goes solid green when the PWM signal tells it to apply full power in one direction, and solid red when the PWM signal tells it to apply full power in the other direction.

If you're not getting a solid yellow when you enable the robot, you need to double-check a couple of things. First, double-check that you have the PWM cable connected properly. One end goes into the Jaguar; the other goes to the Digital Sidecar. Second, make sure that the Digital Sidecar has power and a correct connection to the cRIO digital module that your program is controlling -- and that the cRIO is in the slot the program expects it to be in.
