Looks like quite a few changes with this new format for the BOC.
I got my fishfinder (Fishmark 320) back today from eagle. They said that they didn't find anything wrong with it and it was likely a problem with the power cord or fuse holder. They sent me all new wiring and the fuse holder. What that amounts to is the transducer and everything!
Let me say that before I ever sent the unit in, I went through the wiring very closely to make certain that wasn't the problem. I replaced connectors and made sure everything was clean and tight. I go out and hook up the fishfinder to my "old" wiring. Nothing. I jiggle a connector that I had running to the battery and it comes on

I know I've gone over all this wiring at least 3 times.
Anyway, that's the way it goes, and now I've got a brand new transducer for a spare, LOL.
