pwm cables placement?

[Greg Shaw]

We recently took apart our robot for some repairs and are having connection issues with a victor that controlls our robots chain tower. We know it is a connection problem because the light on the victor keeps blinking. Here is my question: How do you know that the pwm cables are attached properly--you can flip the cables in either direction and it fits in the slot on both the victor and the digital sidecar. You would think that the cables would be designed to prevent plugging in the wrong way--this is not the case. How do we know that the three colored cables are plugged in properely on both the victor and the digital sidecar. This problably sound like a really simplistic question but we are a rookie team learning as we go--thanks in advance for any help.
