i60 Wind - No wind speed Readings

[nveater]

I have an i60 wind software version 1.05- wind speed has either stopped working or shows erratic numbers some of which might be correct- wind angle seems correct although it also has been acting intermittently. At the beginning of the season(2020) the unit appeared to be working- after reviewing this forum I took the following voltage readings

From MHU to Junction
Red 7.9 v
Blue 3.9 v
Green 4.9 v
Yellow 2.9 v

From Junction to unit
Red 7.9 v
Blue 3.2 v
Green 4.8 v
Yellow 2.6 v

The boat was at the dock at the wind was somewhat gusty and swirly. I was unable to measure at instrument because I couldn't pry off bezel ( I could on other instruments- any tips) - I will continue trying- any preliminary thoughts

Thanks
