[QUOTE="Buck, post: 8759397, member: 591582"] It looks like the wire-female clip-fuse connection melted. I agree with whoever said that above. You’d think if it was over current, the fuse would’ve blown properly. Those little dinky tiny looking clips look small. That’s terrible quality, IMO. I would never use 100 amps or anything close to that with fuses that “clip in” like that. Look at the diameter of your wire, then look at how small of cross area those little clips have. There’s too many fluctuations of heat/cold and corrosion that can weaken the grip and cause that very high resistance issue, where you’d get a problem like this, like someone said above. Running electricity though metal can decay it faster, especially if the quality of materials is low. Impure metals can have hot spots within the metal, because the impurities aren’t conductive, so you get more heat in that location (more energy density in conductive parts). Quality matters. That fuse holder is compromised, and I would NEVER use it again. You have a potential fire hazard if you use that holder. I always get ANL fuses, which is also above; they make mini-ANL fuses, too. Every ANL fuse holder I’ve had screws down the fuse, so stuff like this is less likely to happen, and the contact patch of an ANL, where the fuse ends are, is bigger. I’d get a water-resistant one for under the hood, with rubber gaskets to seal off the fuse from water and help against corrosion. People gotta service their audio systems, especially during weather changes. Even ANL fuse holders can loosen up from bass and repetitive temp changes. [/QUOTE]
