"Fuses can sometimes look good but still be faulty."
So true, Mike. This one got me early on in my NT days. I took a trip up to Twisted Throttle for an open house and my GPS was acting flaky the whole way, powering off and on. I was scratching my head because the fuse looked good and my wiring was solid. I got talking to one of the TT techs. He came out and grabbed the fuse and took it into the shop. A few minutes later he was back with a new fuse. He replaced the fuse in my fuseblock and that fixed it, even though the original fuse looked fine! I wouldn't have guessed it in a million years. He had seen fuses like this in the past, so wasn't surprised.
I don't know that he tested the fuse, per se, so I'm not sure it supports your argument of testing components, but fuses are cheap, so no harm/no foul in replacing it.
