I may be telling you something you already know, but a lot can be learned by
looking at the fuses when you remove them.
If the fuse body is blackened, and the inner link destroyed completely, it's
indicative of a catastrophic failure (short) and there is no point in trying
another fuse.
OTOH, if the fuse appears intact and you have to use a DVM to see if it's
open, there's a chance it's just a fatigue break.
