[TG] Wind speed no longer working

[Tom - Raymarine - Moderator]

Hello Matt,

The masthead unit should be outputting 0 - 5V pulses, twice per rotation of the cups. A multimeter will only show the individual pulses if the wind speed is very low, but even if not, if you're seeing a completely static voltage, that's your problem. In normal operation, even a multimeter will show a fluctuating voltage as with wind speed varies.

I think it's most likely that you've got something like moisture in your masthead connector (locking ring insufficiently tight, O-ring seal not properly compressed perhaps) which is bleeding voltage across from red to yellow. It could also be a masthead unit problem. I'd send someone up the mast to have a look into the connector, or remove the masthead sensor and get it checked by a Raymarine service centre.

Regards,
Tom
