Re: [FTC]: Tetrix motor controller weirdness with 4 motors

All wiring was gone through - no tinned wire ends in motor controllers just bare copper, Anderson Power Pole connectors at battery, short USB cable with ferrite core. I think this tells us that the game controller, FCS, Sam module, and NXT were all working, the problem had to be in the Motor Controller(s). A power off and on again and it worked fine.

Had a team with almost the exact issue in a Semi-Final Match. They were using a loaner NXT from another Team that had some age on it (Screen was scarred). I'm not sure if it was their NXT or the V2 motors.
