I have a 1996 Hunter 29.5 that has Autohelm ST30 series of Depth, Wind, and Speed. My Wind transducer with the cups was broken when I bought it. Currently, the depth and speed readings are always at zero, even after I've tried to calibrate them. The previous owner told me I just had to push "reset" when I bought it but so far nothing has worked. I've tried calling Autohelm and then say they don't support ST30 models and to but new ones. I'm thinking maybe they are all tied in together and maybe because the wind transducer is broken nothing is working? Anyone have any ideas, please and thank you.
