Troubleshooting fuseable link failure

I had a local parts store check it they said it was okay now with that internal short show up on that test?

I'd like to think so, but best to check it yourself with the ohm meter. Of all the alternator failures I've had (Chrysler, GM and even one 1960 Ford DC generator), that's not one I've had myself. That's why I'm curious to see or hear about some post-mortems.
edit: Tony (whitepunknitro) says he's seen it with bad diodes. I'm not sure if that would be the cause or the effect but would place the trouble in the rectifier.
