It is not that hard to get the wiring done right. It would be sad if a team really stopped using a common type of sensor because they did not follow some simple instructions and blamed the sensor. Many pieces of industrial electronics products use exactly the same set up to control some function. I have never seen a second resisitor added as a "preventative measure" because it is just not necessary as Alan has stated. Ohm's Law applied correctly to this situation will prove this point.

I would hope that you are doing a thorough check of EACH AND EVERY wire, individually, for ALL of your circuits before turning on the power. Preferably, a second person should also check your work after you have satisfied yourself that you have found and fixed all your errors. An incorrectly wired pot will not damage the CRio but it is quite likely that an incorrectly wired motor controller can become damaged.
