[CA] [CA11] STLK Fail Lightning Issue

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum svbloom,

Unfortunately, the suspected lightning event may well have damaged the communications circuitry within several of the system's components. The only way to effectively test the communications circuitry of these products would be to test each suspect product with an operational product having the same type of communications interface and which was also capable of displaying data from type of device being tested. In this case, it appears that the ST60+ Wind has suffered a failure, necessitating that it be replaced with an i60 Wind as Raymarine's Product Repair Centers can no longer service ST60/ST60+ Instruments. It would be recommended that the SeaTalk buss be reduced the autopilot control head and autopilot course computer. Should the autopilot control head, be able to display rudder angle data and/or command the autopilot into Auto mode (even temporarily) then the communication circuitry of these two devices would be deemed to be operational. The ST60+ Tridata Instrument may then be added to the working SeaTalk buss and the autopilot control head may then be configured to display Depth. If the depth data item is populated, then it also would be deemed to be operational. If not, then the ST60+ Tridata Instrument would be deemed to have suffered a failure and would need to be replace with an i50+ Tridata per my earlier statement regarding servicing ST60+ instruments. The SeaTalk buss of working devices may be interfaced to the SeaTalk to SeaTalkng Converter. After doing so, the MFD's Select Devices list diagnostics feature should be exercised to determine whether the list includes the SeaTalk to SeaTalkng Converter and any other devices listed as having a SeaTalkng network connection. If listed, then the MFD's SeaTalkng communications circuitry as well as that of the SeaTalk to SeaTalkng Converter would be deemed to be operational. However, should the MFD when configured to display the Heading data item list dashes instead of a value, then it would be recommended that the ST-STng Converter be replaced. Should the MFD's Select Devices List not list the ST-STng Converter or any other devices having a SeaTalkng/NMEA 2000 communications interface which have been interfaced to the backbone, then it would be recommended that both the MFD and ST-STng Converter be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
