servo jitters

[jon-s]

When the servo jitters (I don't recall any sound), it moves back and forth, up to about 50 degrees. It does this regardless of what position it starts in. It has done this on both of our robots.

It is plugged into the sidecar and should have a jumper on it. The servo moves a thin 2 inch long arm. I think this is the first year our team has used the servos, they've only been moved maybe a dozen times. People have backdriven them, but not very often. The wires and cable cross at about 60 degrees to each-other.
