Testing a fuse with a multimeter is a simple process that can help you determine if the fuse is blown and needs to be replaced. A fuse is a safety device that protects an electrical circuit from damage by breaking the circuit if the current flow exceeds a certain level. Fuses are typically made of a thin wire that melts and breaks the circuit when the current flow becomes too high.
To test a fuse with a multimeter, you will need to set the multimeter to the ohms setting. Then, touch the probes of the multimeter to the two terminals of the fuse. If the fuse is good, the multimeter will read 0 ohms. If the fuse is blown, the multimeter will read infinity ohms.
