Vex Joystick Issues

We have just changed our joysticks because one of them broke. The new joystick, which is the main joystick, stops sending input at random times. The other controller still sends input and the robot continues to function. Are there any ways to fix this issue besides getting a different joystick?

Try connecting a 9 volt battery to the brain, that’ll increase the strength of the connection. As for the old joystick still sending input to the brain, try connecting the old joystick to a different cortex to cut the connection between your current cortex. We’ve had problems like this before so I hope this helps.
