Don;
Try cleaning the rheostat with tuner bath or alcohol
and also check the wires going to it in case one might be breaking. If it is in
fact a rheostat, and not a rotary switch, it should very the resistance
from high to low in a linear fashion, like from 0 to 100 ohms for
example. The easiest way to check is with an ohmmeter between the slider
and one of the outer connections while moving the knob back and forth. With
regard to the position of the knob, do the lights come on when it reaches the
end or do they come on in the middle someplace? Hopefully the reason
that it doesn't work if from dirt and disuse and not wear.
