Try checking to see whether the yellow and green wires are reversed, or
that they're connected to the right terminals.  On some of the Vista
panels, I've noticed that if you don't look at the board at just the
right angle, it would be easy to wire to the wrong terminals.  It
sometimes helps to be able to count too. :-)
