Bob,

I have been following the responses and I thought the same thing as the others that a wire connection swap would solve it.  Since you tried another control box and also a wire connection swap to the box, and your spare rotator works properly,  I guess the only thing left is the rotator itself.  I don’t understand what could be happening in the rotator that could be causing the reverse rotation thing though.  There are a couple of rotator repair sites on line Norm’s Rotators is one that does a lot of the Ham 4’s and Tailtwister repairs and refurbs.  I would email him and see what he thinks.  Of course the first thing he is going to say is the wires are reversed,  hihi.  

73,
