Did you check the main fuse at the battery as well? This is (usually) in a small rubber holder a few inches from the positive battery terminal. It is possible that it blew before the protection in the jack, however none of your other 12V would be working with shore power disconnected.
BTW, make sure you don't fully retract the jack as this often blows the fuse with a current spike as the motor strains. Many put a mark (or accentuate the one already there) on the jack bottom to remind themselves where to stop.
