I'm sorry, I needed a comma there. The 26vdc is dead on. The red moves
normally, the blue moves up and down normally, it just won't move to the
right far enough. I would normally suspect a non-tech going in mis
adjusting something, but I know for a fact that this a virgin. I replaced
all 3 stks' now, and no change. TIA
