I found the wind assembly to replace to fix this Davis 7345.271 ( wind speed cartridge ) .
on the vantage vue outdoor assembly , remove wind cups, remove 4 screws under unit.
The top and bottom will seperate, remove two more screws inside wind speed top to replace unit.
No wires , 10 minutes and your running again. This unit is 5+ yeas old. about $15 dollars shipped
from Scaled Instruments Gainsville FL.
I am very happy to have my vantage vue fully functional again.
