[CQ-Contest] Yaesu G-450 Rotor question

I have been given a G-450 rotor that has a problem.

The indicator needle acts like it has a mind of it's own!  Sometimes it 
track the rotor, for several degrees and then stop.  Sometimes it will just 
sit there "shaking" back and forth between CCW and CW.  Sometimes it will go 
from CCW to CW while the rotor is still moving in the CCW direction.  There 
is no pattern to what it does.  At least none that I can spot.

The rotor part turns as it should.

I have checked, with an ohm meter, both pots.  Then both change resistance 
as they should with no jumping around.  All wires check out OK.

Has anyone else seen something like this and if so, what was the fix?  I 
really don't want to spend the money sending it back Yasue for repair!!

And all I have left to trouble shoot with is normal multi meters.

Thanks for any hints....

OK, back in my hole,
