Although I can't speak for exactly what Mark said as I wasn't present, as we turn on our robot from the breaker our Victor 888 speed controllers randomly give power to any motor controlled with a Victor 888. I do believe he said that it could be one speed controller causing the whole problem, but we haven't had time to test it yet. While disabled (meaning teleop and autonomous were not running), the LEDs mainly were completely off for the short spurts the motors moved. While in teleop, this behavior seemed to occur a bit more frequently except the other indication colors on the LEDs appeared. Again, this occurred without any code telling it to do so, as we once removed a PWM wire from one and the motor still continued as such. As Brian implied, the robot was acting normally before a couple days ago when it started acting like this.
Hope this helps, if you need more info please feel free to contact me.
