Marty,
Here is one more empty head thought, I have run into problems where I would be floored, I did every thing just as it needed to be done (wiring) and the project would not work. I checked it all out and every thing was right, I could see no error. I went back took it all apart and started from scratch, rewired it and found as I went along where I had made a mistake. This stuff is pretty simple but sometimes I was just not seeing what I was doing amiss.
Just a thought.
