Anybody ever have a fuse fail in the "non-visible" part of the fuse? I did. Fuse looked visibly fine, but it was dead when I got a multi-meter on it.

Ruint a track day trying to hunt this failure down......

I guess always just a smart thing when you have a weird electrical failure to replace a few critical fuses one by one and see what you get (or carry a multimeter, which I will now do at Dr. Earp's command......).
