Thomas,
If you color code everything on the robot, then you will have little to figure out when something goes wrong. We use a 3M color wheel, available from Digikey to mark everything. One of our motors is the red motor, so the motor receives a red tape, the position on the robot is coded red, the wires leading to the motor, the speed controller, the wires leading to the speed controller, the PWM cable, the location on the breakout where the PWM is attached, the breaker and it's position on the breaker panel is all coded the same color. If the red motor is not turning, we look at the red speed controller to see if it is powered, then check to see if the red PWM is plugged in at both positions, etc. Programmers help generate the motor list and colors so everyone is on the same "page".
