Hello. I have a problem and I'm not sure where to look (literally). I just bought a 1984 Silverton 34 (convertable?) The boat has three batteries - all fully charged - two starting and one house. Almost nothing in my 12v system has power (one radio and one chartplotter on the bridge have power, but the other pair do not). Engines have power and start (separate batteries). I have double-checked the battery charge level, and cleaned/tightened connections at the battery. I am suspecting either a ground or a positive is bad/broken, or maybe there is a fuse out. But I have no idea where to look. It seems like there should be a power distribution panel/buss somewhere, but I have not yet found it. Following the cables from the battery was useless since they disappear into the interior. Can someone point me in the right direction? I find it hard to believe that a boat like this doesn't have a fuse/breaker panel somewhere (and maybe I'm just blind). Thanks in advance!
