Anyone have electrical diagrams for the annunciator control panel? Mine just blinks when any switch is pushed? (one blink, then nothing) After a few minutes, it will do the same thing again.

Are you talking about the panel with switches for pump, tank levels and so on?

Can't help you with a wiring diagram, but you might check Colaw's for a replacement (if they made it through the tornado ok).

Your 12vdc supply to your panel is probably failing. A poor connection would allow some current to flow and charge the caps on the board. Pushing a button would allow some LED activity untill the cap discharged.
An easy way to troubleshoot this is check both +&- supply connections at the monitor. Using a test light and available known voltage (like a nearby light) reference to the monitor supply points.

Thanks. I am working on getting that done. My panel is mounted on the dash board, thus is 'stand on your head' for access. It strikes me that it could be a failing ground as well as the power? There are two plug-ins to the board, each with several wires attached, thus a diagram would help to identify the power supply.
