We like testing our fuses with a multimeter. We have a basic multimeter here. 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. Since we'll be measuring ohms, move the dial to ohms.
