Which fuse on the engine blew? And did it re-blow when you installed a new fuse?

OK

There isn't a fuse that is specifically for the alternator. What was the amp rating on this fuse that blew? This is going to be more complicated than you think, are you near the outboard now?

No - Ill check back with the site when I get to the Marina. Thanks for the help.
Marine Mechanic: Jason, Marine Mechanic replied 2 months ago

If you look at the fuse holder itself, what I need to know are 2 things. I need to know the amp rating on the fuse that blew. then, I need to know the color of the 2 wires that go to that specific fuse.
