Speed/Temp transducer

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum tstano,

Please click here to view a FAQ addressing this subject. The test referenced within this FAQ does not call for a voltage test. Instead it calls for a resistance/continuity test. Should the test match the results specified within the referenced FAQ and the ST50 Speed/Tridata display that the transducer has been interfaced to not report speed, then the display would be deemed to have suffered a failure and would need to be replaced. Within Raymarine's current instrument products, the i50 Speed and i50 Tridata instrument displays support speed through water.
