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.
