Let's not forget that in the world of fuse protection our trucks only had the crudest and simplest form of protection from the factory, since that was all that was needed. No sophisticated electronics here. So if the voltage and amperage rating is the same, the size is the same and the internal element is the same basic size and shape the fuse will provide the all the protection need for one of our stock trucks. How many of you have bought a running driving vehicle only to discover later one of the fuses had been replaced with a gum wrapper?
If you have added aftermarket equipment then be sure to fuse it according to the manufacturer's requirements. |
Heh, where I used to work we had remote controlled positioning equipment for antenna testing. Sometimes there would be an intermittent problem. We all know what that's like. The range maintenance guy would come out, and not find the problem, since the equipment decided to work again. One guy's solution was to put in a "#10-32 AGC fuse",
as he called it. Then range maintenance was called, and the melted/scorched component replaced. That guy is lucky nothing got burnt down with a machine screw instead of a fuse in the slot.
