I am trying to help my Uncle solve a problem w/his Cat. His aerator will not work on manual or auto, the control panel BP2000 keeps showing fault when trying use it. I have tried to switch the pump out which I believe is the one located at the bottom of the livewell on the port side. It is also showing fault when turning on the bilge pump but the bilge pump still runs. There is a breaker with red button underneath the fresh water in and water out rocker switch that says "pro-air" and another that says "Acc" I have pushed both of those to no avail. Any ideas?
