ST70 wont run calibrate vane test

[Andrew41]

Hello I am hoping you can help me with an issue.

I recently removed a faulty wind pod with an iTc-5. The replacement went well and the wind speed and instrument readings look reasonable. I assume I need to calibrate the vane to the new transducer. Through the ST70 I have attempted the calibrate wind vane (where you go in slow circles) many times without success. It either "hangs up" at the 6% complete mark or stays at 0% no matter how long I go in circles. It doesn't say to slow down or anything. The small blue circle shows it is "working" during the test but the test will not progress and complete. I can align the vane (head into the wind to adjust AWA) no problem. As a result of not getting this alignment to work the true wind and angle is way off. My software version on the ST70 is 3.03.

Please help!
