I have a 1996 Hunter 29.5 sailboat that has Raymarine ST 30 series of electronics (which I hear Raymarine doesn't service anymore). The wind transducer with the cups on the top of the mast is broken and the depth and speed sensors just read Zero all the time even when they are reset. Is that the sea talk that makes all of the not work if one is broken? I'm trying to diagnose the problem before I decide if I have to buy new ones. Thank you for any input on my problem.
