Adam, I'll have to check different areas of the control board to determine where I'm loosing the signal. One thing is: when I made my final power connections to my controller I followed the schematic 1-5 although I felt the order was the other way 5-1 around. The wires you see in the picture were according to the schematic and I did put +12v into the board. Can "U9" handle that kind of abuse? Work is looming on the horizon so I may have to come back tomorrow for more fun.
Thanks for your help.
Mike
