kstl,
When I mention color code I am referring to our method which color codes everything. We use the 3M color tape wheels (available from Digikey and others). Everything is coded. The motor, the motor position on the robot, the motor wiring, the speed controller, the power wiring to the speed controller, the pwm cable (both ends) the position on the sidecar, the breaker and the breaker position on the PD.
If the red motor is not moving, you look for the red controller to see if it has power. If not, you check to see that there is a red breaker in place. If the controller is powered but showing no PWM connected, you look for the red PWM cable and make sure it is connected at both ends as it is marked. It sounds harder than it is. We use a spreadsheet with the codes marked on it for communication between the software, hardware and electrical teams so we are all on the same page.
