Raymarine C80

[Amalfi]

Anyone got any suggestions as to what might be causing an intermittent fault on my Raymarine C80. I keep losing data from my depth sounder module. Everything looks ok and sometimes it will work for several hours before coming up with the data lost alarm. it then might not function for hours or sometimes days before springing back to life. I have checked out the connections, done a reset of all the settings and now I'm scratching my head and don't know what to try next. Any ideas.

Aren't these depth sounder modules very voltage sensitive? What's happening with the supply voltage when you have the problem?

Had something similar happening on a RL70 - mine was the GPS fix. I was convinced it was the GPS mushroom but in the end it was a corroded connection on the incoming cable on the display. Could not really see much, I just cleaned everything best I could on the connectors and it solved the prob. Maybe you could trace the cables enough to check the plug connections from one to t'other, you may be fortunate and solve it - worth a try?

Good luck.

Yes they are (Hi Jimmy) a common problem is the lead that comes from "mains in" is not thick enough and you have a voltage drop, that wire needs to be a good thickness, quality cable if you just tap into a 12v from a switch it may be that the wire is not man enough for the job.

Suggest a thicker wire from battery through a fuse to the DM box and from DM box through the switch.

If it does the same as mine before fault found, as you go along you get a noise on the radio, then you get the data lost come up on screen, you acknowledge and all is ok for few mins.

Thanks for the suggestions. Come to think of it I sometimes lose position fix as well but assumed this was something to do with satellite positions as it usually comes back on in a few minutes. Will check out the wiring and the connections tomorrow.

Sorry - only just seen this thread - and Jimmy's/SolentPhil's comment.

I believe that there is an inherrent problem with some of the Raymarine DSM units.
I assume you have one of the Raymarine DSM's (30 or 300 - I think the models are)
I believe that some dont like to be run under 24v - My system has a DC/DC converter and runs the DSM off 12v.
However we also did loose data from it once - reboot sorted it.

I had and still have, to a degree, a similar problem with the depth sounder. Had a raymarine chap look at it. One fault he found was that the cheap shoot through hull transducer only had a small bit of ATF in it - he said to clean it out and fill the bowl with glycerine - this certainly helped and I no longer loose data for more than a few seconds. However I still get "DSM module not connected" message after starting the engine while I have the C80 screen powered up - it comes back on line a few seconds after me acknowledging the message -so guess this could be a voltage problem / wiring prob as suggested by another poster?

I get this same dropout when starting one of the engines. I wondered if it might be possible to fit a big capacitor similar to those fitted to big car stereos?
