Yes sir I'm having a problem with the depth finder loosing power. It will go off and maybe a hour later come back on. I think it could be a relay tripping and coming back when it cools. It's also loose of power to other switches on the dash. I also can not find a fuse box. I've been looking for it be because the 12v power port has no power. Need to find fuse box. Maybe you can help. Thank you.
