Late last summer my horn, wipers and nav lights stopped working at the same time. It was the end of the season, so I didn't troubleshoot it. Now I am prepping the boat for the season I want to look into it. Since the all stopped working at the same time I am thinking fuse or breaker. I checked the fuses in the fuse box in the console and they are fine. The breakers in the battery switch box are the red push buttons. They look ok but I haven't pulled them out and looked closely. Are there any inline fuses I should look at? In the hull near the batteries there are some electrical connections. Are there fuses in those connection? I have the manual but it is not clear. Thanks
