Just an FYI...
I reversed the m1 and m2 wires in back of the asc1 and when I pressed west, it still moved east.
First time I did this it didn't move either way.
OK, so the initial problem that you reported was that the dish would not move West and displayed an error. After testing, we know that the ASC1 West Drive circuit does not have defect.
With the wires still swapped (reversed), if you press the East button, does the dish move West?
