My VHF blew its fuse earlier this week for reasons unknown. Well, I
assumed it did, because it suddenly stopped working. When I took it home
and plugged it into my 12V battery eliminator, it fired right up.

So I went poking around the fuse panel. First accessory fuseholder I
opened had a blown fuse, so I replaced it. No joy with the radio.
Obviously, another fuseholder, so I kept on looking and found the devil.

Now, since every other accessory circuit on the boat was working, what
the hell was NOT working because of the first blown fuse I found?

Grrrr.

Have you got a diagram/list of what is on each fuse/circuit breaker?
