Our St50 wind indicator has stopped working, the wind speed is ok but direction isn't. Has anyone a wiring diagram for this unit and suggestions for checking where the fault may be? Many thanks.
If it's like the ST60, which I believe it is, the fault is most likely to be in the circuit board. You can check the output wiring with a multimeter and it will soon identify the problem. The information as to which wires should generate what voltage is widely available on the web and on Raymarine's website.
