[TG] [TG11] No sea temperature on MFD

[Tom - Raymarine - Moderator]

Hello jgol,

Is speed data ok?
On the DST, do you have the bare/shield wire connected to the Depth terminals or Speed?
What specific value do you see for water temperature? Is it zeroes, dashes ( -.-F ) or something else?

You can test the thermistor sensor inside the DST800 analogue transducer by disconnecting it from the ITC5 and measuring for resistance between the brown and white wires: this is a resistance that will decrease as temperature increases, where 10kOhms = 25 degrees C. You should see something between around 7k and 13kOhms. If you don't then that would suggest a transducer problem.

Regards,
Tom
