Dig into your parts bins and find a 500-ohm (linear taper is best) pot and
put it across the appropriate control box terminals (after disconnecting the
rotator pot wires, of course)?  If you still get meter swings, that should
verify the problem is internal to the box and not the control cable or
rotator.
