Re: Ignition problem, stumped!
A voltmeter reads state of charge, an ammeter shows only if power is flowing, being produced or consumed. So if there's a voltmeter it is just showing that your battery has a charge on it. If there's an ammeter, different story.
Old boats usually didn't have a battery primary fuse, which would be located within a foot of the positive terminal generally. You'd have to follow the battery positive lead to see where the first fuse(s) have been installed. If nothing at all works, that's a good sign there's a blown fuse, or a primary wire has come loose, or corroded badly.
