Well, you should check your motors for shorts to ground. Probably
you should also check each winding for resistance, and compare to
the X motor. This still doesn't guarantee the motor is good, but it reduces
the probability that it is bad.

Did you actually find a loose wire? The loose wire doesn't need to short
to anything. Just being loose can permit sparking that can pop the
transistors
in the Gecko.
