If a device is not working, you should test the fuses. However, some fuses will create that blackened stain after only slightly overheating, and that may have even been the result of an unnoticed incident weeks or months earlier. If the translucent area is blackened, it is usually because the fuse has burned out. These draw excess power that exceeds the capacity of the fuse. A circuit overload occurs when too many plug-in appliances are connected to the circuit. They are made clear so that you can see if the wire remains intact. For the main fuses, the amperage rating is often 60-amp while cartridge fuses for appliance circuits are rated 30 or 40-amp. Many types of fuses allow for visual confirmation that the fuse is still functional.Testing fuses with a multimeter is comparatively simple to do, and the equipment involved is cheap and easy to operate. In addition, most car parts can only be tested at repair shops, and to do so will usually cost quite a lot of money. Other components in your car or home involve complex wiring systems that run on for some length. It is easier to test fuses than it is to test other electrical equipment.Testing fuses is the simplest way to examine what is going on in the electrical systems of your car or home, and for that reason, it is a vital skill to possess.

X Trustworthy Source PubMed Central Journal archive from the U.S. Blade fuses plug conveniently into banks, and relatively little space is required to house a large number of them together. Previously, most vehicles also contained small glass cartridge fuses. They vaguely resemble the plug of a power cord, with two metal prongs emanating from a plastic housing that contains the wire. The blade fuse is a common type of automotive fuse that has come into use in the last 20-30 years.They have metal contact or terminal points on either end and consist primarily of a tube that contains the wire. The cartridge fuse is a cylindrical fuse that has been common in a wide variety of devices for many years, from homes to small electronic devices.Here is a description of the two you are most likely to see: There are several varieties of fuses, but their differences are primarily in appearance. If too much power runs through the fuse, it will "burn out," quite literally, and open the circuit, preventing the current from flowing through the circuit. Fuses are really just wires that are designed not to last, but their purpose is to prevent damage to more valuable electrical equipment or prevent fires (especially in homes) caused by power surges.
