That's a more remote possibility, but possibly true. Unless you have the exact same motors wired the exact same way, they might still turn differently. If a multimeter reads the same voltage when you put the red probe on M+ and the black probe on M-, then I would definitely agree with your assessment.

If it is bad internal LED wiring and the Talon is new, I would talk with Vex, Andymark, Cross the Road, or FIRST about getting a replacement. That LED is valuable for troubleshooting, and if all the fault codes are in flashing green, that's going to be extremely confusing.
