[C320-list] Depth Sounder

[Chris Burti]

   - Sorry, I hit <send> too soon... there are test procedures and I am
   reasonably certain that you can find them easily in the Raymarine tech
   forums. If your instrument wire is like mine in a continuous run from the
   sealed transducer at the bow to the i5 adapter buss in the aft locker and a
   second run from there to the pod on the pedestal, the latter run is easy to
   check connections and continuity (google a YouTube video for 'continuity
   test' if you don't know how - it is easy) and is the most likely source of
   a problem. If the problem isn't there, you will need to test the transducer
   using an ohm meter and the test procedure on the Ray tech forum, I believe
   this will disclose a continuity failure as well as a defect in the
   transducer
