A fuse is a safety device that protects an electrical circuit from damage caused by overcurrent or short circuit. When too much current flows through a circuit, the fuse melts, breaking the circuit and preventing further damage. Checking for a blown fuse is a simple but important task that can help you troubleshoot electrical problems in your home or vehicle.
To check for a blown fuse, you will need a fuse tester or a multimeter. A fuse tester is a small, handheld device that can be used to test fuses quickly and easily. A multimeter is a more versatile tool that can be used to test fuses, as well as other electrical components.
