I removed the turnout with the open coil from the layout so I could see more clearly how it works.
The sluggish operation is a result of friction far to great for the fine, piano-wire spring to overcome.
I tried dry molylube on the sliding surfaces of the turnout mechanism. I do not think this really improved the operation of the turnout. It appeared to me that the friction might be between the points and the ties. I hypothesize that the track was pushed downward through overly energetic track cleaning. I gently levered it upwards. For the moment, the points now move back and forth readily with just the force of the spring.
The coil had clearly overheated. The connection to the switched power line was clearly broken. I have the coil out. It is not clear to me how I should clean the finish (varnish) from the free ends of the coils so that I can:
1) check to see if there is continuity across the remaining coil, and if there is,
2) resolder the leads to the switched power line.
I would also like others to share what they have learned about how one resolders the fine wire coil windings to the power leads. Clearly someone did it at the factory.
Thanks
