I came off some pretty rough seas a few days back. Everything worked fine. The next day when I fired everything up the autopilot controls and AIS etc (2 small screens on lower helm and one on upper) did not power up. I looked at the ACU400 and found the 3 Amp fuse blown. I replaced it and it blew immediately. After talking with Ray Marine they suggested I remove the Seatalk and replace the fuse. If the power to the seatalk from the ACU400 was normal then it is not the ACU400 but likely a short somewhere, worn wire etc. I did this and the power from the unit is fine with the Seatalk disconnected. Blows fuse immediatly when connected. Has anyone had a similar problem and can point me in a probable problem location?
