Well I have not waxed the side walls as yet. The baby powder or talc seems to make some sense also. Replacing both circuit breakers will be the last thing I do. Will the circuit breakers show a lower voltage from one side to the other? I did not check that so I suppose I can do that also. They are only 4 years old.
I did not say the slide was gear driven but yes, it is a gear driven slide. The other 2 slides are cable driven and seem to work fine so that leads me to believe it's drag related. Waxing will commence shortly.
