The fuse should be located on your battery switch box. Check it first...
After you have confirmed that fuse is good (or replaced) Try your dash switch again. If the pump works then get out your garden hose and fill the bilge until the automatic switch kicks in. Unfortunately Four Winns places covers over their switches so you can't just reach down and lift it.
Absolutely make sure both the systems work before trusting your boat in the water. If either system doesn't work then your into tearing out and replacing your pump and switch. You may as well go bigger to something like a 2000GPH...
I just did all this but didn't take pictures.
