[C320-list] depthsounder problem

[lwhite808 at gmail.com]

  My '99 320, hull number 624, has the same Autohelm (now owned by Raymarine) instruments in a navpod at the helm station that most of you have.  Following a recent cruise to Molokai, Lanai, and Maui, which included some wave-bashing channel crossings, my faithful depthsounder went blank.  After the trip, I opened the pod and took apart the connections, to all the instruments, and squirted them with WD 40.  Now the sounder flashes 0.0 ft, and I'm wondering whether any owners in our online help group has a suggestion for a next step.  I don't suspect the tranducer in the bow, or the cabling running aft, which leads me back to the instrument at the helm.  Any ideas?  By the way, Mike Matthews, who owns one of four 320's in Hawai'i, is probably at sea or back in California.  After buying the boat years ago, he sailed it to Hawai'i, lived aboard, then missed California so sailed back to the coast, then missed Hawai'i so he did a return voyage, and has now disappeared again, so I suspect he's back on the West coast.  These are passages of thousands of miles, and he sails alone!  These are tough boats.....   Thanks for any suggestions about the depthsounder.      Dave White, Honolulu Hawai'i, C320 Tradewind
