[TG] Seatalk Failure

RE: Seatalk Failure
Hello Chris,

A steady voltage yellow-shield on Seatalk doesn't sound good, but most multimeters, even high-quality ones, are much too slow to show the individual data. You might get somewhere connecting just power to the pilot display and then measuring yellow-shield voltage there as a comparison?

Unless you can borrow another Seatalk device (e.g. a chartplotter) which is capable of talking to either of the other two and listing whether it's communicating or not in its diagnostic page, I don't think you're going to be able to go a lot further with this yourself. I think the options are:
  • borrow a chartplotter, e.g. C/E Classic or C/E-Widescreen, which can diagnose Seatalk traffic
  • replace the pilot complete
  • have a local Raymarine technical service dealer diagnose the issue for you

You can find local service dealers by ticking 'Certified Installation' at


Raymarine since 1999.
Interests: Diagnosis of problems in sonar/fishfinders, NMEA2000, ethernet comms, autopilots, thermal cameras
