[CA] [CA11] Wind instrument not reading speed

[MarkXal]

Hello,

I just finished installing a E22079 wind transducer combined with a ST800 through hull transducer, which are connected to an ITC-5 and i70s display.
All devices were tested at home last fall and worked perfectly. The wind transducer was installed on the orizontal mast of the sailboat in the fall and left to winter there. This spring I raised the mast and completed the connections, and unfortunately I found out everything worked except the wind speed measurements. These were my observations:

_the yellow wire of the wind transducer was mistakenly plugged in the socket just under the correct spot on the ITC-5. This was corrected
_reading voltage with a multimeter on the yellow wire gives approximately 3.15Vdc, which varies slightly with time
_the cups of the wind transducer were turning as expected
_the red wire had 8Vdc and the black wire had 0vdc as expected.
_the ITC-5 shows wind speed measurement timeout, but no other errors

My question is, is there something I am missing, and if something is broken, what needs to be replaced?
