The fuse should only control the starter solenoid. Sounds like the solenoid is bad, causing the fuse to blow. The starter solenoid feeder is unfused from the battery. If you need to get it started, you can jump the solenoid contacts (careful), while someone turns the key. Leave the fuse out. Dunno if that fuse also runs the ignition circuit as well, hope not. If you do get her started, -dont- turn it off!
good luck
