Have a 1973 Belboa 26. Can anyone help with the electrical system? It would be awesome if there were a Schematic Diagram but I think that's a pipe dream. Hope everyone is enjoying their summer sailing. Any help is appreciated, my main issue is the rectifier & how it's suppose to be connected. Currently when the boat is plugged in it does not charge the batteries also the fridge is another area I could use some knowledge or elect advice. thank you, enjoy
