Raymarine Tri-Instrument Failure

[rk6johnson]

I have the typical Raymarine tri-instrument pack on my 2008 Catalina 309. Depth/Speed Meter, Wind Instrument, and Autohelm (St3000 I think). All was fine until a week ago. We had some Engine Maintenance recently, required starter cable disconnect, but no other work or events.

Currently, the Depth/Speed Meter will not turn on, the Wind Instrument is on and beeps, but no numeric read out-only dashes. Direction indicator seems to work. Autohelm says something like "No Seatalk Connection".

I turned off a couple times, turned off 12 volt selector then back on, but no change. I have a marine electronics guy coming in 2 weeks, but would like to get this fixed myself. Any suggestions?

More likely ST4000 or 6000 if it's 2008 vintage.

Two words for you.. Power and connections.

check your wiring. It sounds like something got disconnected someplace, or that the wiring was damaged when the engine work was done.

Because SeaTalk is a bus, any one instrument failure can jam the bus and present those symptoms. You can try unplugging/bypassing one at a time to isolate which are healthy. I would bet that connecting only the Autopilot head will fix the "STLK FAIL" message. Then try wind or speed/depth in turn and see what combo works; the one that kills all when you plug it in is the culprit.
If you're lucky, it just one of the plugs that got worked loose..
