Wind data missing

Dear Moderador, I had an issue on my wind data not showing properly on ST60+ graphic displays on a mast bracket, nor on the rest of the system, so I swap the wind vane with a friend's boat and my wind vane worked normaly, on my system the mast cable goes trough a Wind Pod (E22108) and then to the A70D gps/plotter, all other data (speed, depth,gps) are working in the system, how could I test the Wind Pod or could I change the Pod to an iTC5 ?
Regards
My system: ST60+graphic, ST70, A70D, VHF RAY 49E, Auto Pilot ST6002, i70
