Testing a fuse with a multimeter is straightforward. Set the multimeter to the continuity or resistance setting. Place one probe on each end of the fuse. If you hear a beep or see a low resistance reading, the fuse is good. No beep or a high resistance means the fuse is blown. Have you used a multimeter for other electrical checks before, or is this your first time exploring fuses? Let me know if you need tips on getting started!
