Wind Transducer & 290 Wind pod

Advice needed - Wind direction will not match actual Wind direction – it does move, seemingly randomly (and wind speed does show). After attempts to calibrate to the wind direction manually, the indicator does not stay aligned to the actual Wind.

This is a ST290 System, installed in 2003. Prior Depth pod updates, but I don’t recall ever updating the Wind pod.

Wind Pod Voltage to Shield, as follows
Red 5.28V
Blue 2.45
Green 3.45
Yellow 2.2

Do these figures provide any help in whether it is the transducer or the Wind pod that is malfunctioning? Thanks for your help.
