I am looking for help. Last weekend I experienced the "loss of CAN Signal" with some erratic behavior. It was inconsistent, but affected seemingly all areas of the boat except ballast controls, audio, and aux switches. Sometimes it would start immediately after the 4th digit of the code was entered, sometimes it would not start at all, sometimes it needed key start. I tried to disable the 4 digit code and it started as soon as I hit the power button (Scary!) Most times I need to hit the main power button to stop the engine. Gauges all seem to freeze, showing no rpms, voltage, etc. I do seem to see engine, air and water temp. I have gone everywhere that I can find to check grounds, loose connections, etc. I left the one year old batteries on a trickle charger all week. so I am pretty confident in them. Over the past few months I have seen some occasional issues flare up wit the depth finder. For example, when I am floating in 20' of water, the depth might read 2' for a minute or 2 then revert back to a reasonable number. Is there any easy way to isolate this from the system to identify if a bad transducer might be the issue? When I trace the depth finer transducer wire form the depth finder, it disappears into a stringer before any connections... What other steps can I take? I really don't want to haul this ting out of the water if I can avoid it and I am sure that anything but routine maintenance from dealer mobile crew is begging for a long and expensive process just to troubleshoot. We have alot of summer left and I would really appreciate any advice / education that any of you can offer. I am pretty sound mechanically, but I never have been good at all of that mysterious electrical stuff!
