Check where the regulated 5vdc comes out of the MCB then check all tranducers for a good connection and for no corrosion and moisture. Then check the wire nut where all of the tranducers get there power and last thing check all connections on the ADI board. If this dose not work call your local McQuay Factory Service they should be able to help.
