(You might not get the described results with the speed signal, az it is infact a square wave signal, the faster the wind blows, that higher its frequency. Depending on the meter you use, you might get alternating values or the described voltages.)
If you do not get these values, suspect the transducer or the cabling.

Auto helm St 50 plus
The wind direction vane on St 50 was corroded and so we took it off and lubricated the pin until it turned easily. On reconnecting the digital display just had 2 dashes and no speed was showing. Does this mean it is broken or needs recalibration or a poor connection?
