Well that's great, always nice to have a successful result and if it happens again you'll instantly be on top of it.
Actually I just came in from doing exactly what I recommended you do. As Brian pointed out, the small red led that comes on when the fuse is blown still conducts some current so checking the terminal might be misleading. But it's not really. My voltage was about 12.6. When I pulled the fuse and checked the terminal again it was 11.4 So checking the output terminal does indicate a blown fuse, just not as graphically as one that doesn't have an led.
At any rate, glad your trouble shooting was successful and if you have the fuse blow again let us know.
