Bob, in your first post in this thread, you said that "When I have it out of gear with the parking brake on and I push the air button the lights all flash on, the red ones go out, the 4 yellow stay on until I take my finger off the air switch, then only light is the travel light." That may indicate that the computer has a problem. The manual indicates that there should NEVER be more than 2 yellow lights on at a time and the the right and left side yellow lights should not be on at the same time nor should the front and rear yellow lights be on at the same time. That would indicate the all 4 sides are low which is nonsense.

Take a look at http://www.beamalarm.com/Documents/hwh/h...ained.html Section 3.9 near the bottom of the document. They give some suggestion on troubleshooting.
