***On power up, if the RED Fault LED on the motor driver board is lit right away, then
there is a problem:

2. On the motor, there is a set of five wires that go to the small circuit board located
on the motor. This set of wires may be damaged, or the plug is not seated properly.
3. If the motor has been plugged into the Master Controller using ANY port other
than the MTR Logic port, the motor may have been damaged causing this fault.
