Hi, Colin -- the resistance tests others have mentioned can be run on the raw transducer itself, if you can identify the proper pins in the connector. I would guess that the connector at the masthead is probably corroded beyond repair, and you should consider replacing the whole cable/masthead connector assembly (Raymarine part #A28163) rather than try to troubleshoot a bad cable. BEFORE you run that up the mast, connect the old transducer to it and connect to the wind instrument, and see if the old transducer still works; or just run the resistance tests through the cable and see what happens. This will tell you if you need a new masthead transducer, as well (Raymarine part #R28170).
The transducers are definitely NOT attached permanently to the cable; and no, Seatalk cable won't work -- as mentioned before, it's four-conductor stranded with shield, where Seatalk is two heavier conductors with shield.
