Subject:Re: Crumar Mojo half moon switch weirdness

You might also find that it's the cable of the halfmoon. The Mojo uses
a different wiring scheme than most, which is designed to allow the
organ to auto-sense the halfmoon. It requires that at least one pin is
tied to ground at all times. If the connection is intermittent, I would
imagine that the Mojo might 'discover' that the halfmoon was unplugged.
