If your position isn't changing then it's your encoder, or the wiring. I've had a few of mine come apart and do the same thing. The rotary part of the encoder(not sure what it's called) is glued onto the shaft and I've had 2 of mine come unglued, i tried to repair them but just wasted my time and ended up replacing them. Milltronics has replacements for about $300 but you do have to change the wiring a bit when you put the new ones in.
If I remember right i had to reverse the signal wires.
I'd also clean up your tach while your in there, a dirty tach can make it grumble like it has bad bearings
