Glass fuses have a low breaking capacity. It's easy to see when they're blown: the glass will be discolored and the filament broken. Replace yours today!

Ceramic fuses are high or low breaking capacity and can be used in many applications. Ceramic color can vary from a very light beige to dark gray.

If your multimeter stops reading amperes you may have blown a fuse! In most cases, you will still be able to read the resistance, voltage, and other values. The most common fuses in multimeters are certain glass and ceramic fuses like Bussmann AGX-2, GDA-630mA, and SIBA ceramic fuses. Fluke has a lot of different part numbers and some are for the exact same fuse.

Continuity testers are a simple replacement to multimeters. Similarly, simply touch the probe and clips to the end of a fuse to test it. If the tester lights up, the fuse is working. Be sure there is no current running through the fuse before testing.

Multimeters can test the flow of current, voltage, and electrical current. It will send a current through one lead and measure it through the other. To test a fuse, you can measure its continuity or ohms, but we will be testing for ohms.
