To check a fuse with a multimeter, follow these steps: (1) Set the multimeter to the continuity or resistance setting. (2) Remove the fuse from its holder. (3) Touch the multimeter probes to each end of the fuse. (4) If the multimeter beeps or shows a low resistance value, the fuse is good. If it shows no reading or an infinite resistance, the fuse is blown and needs replacement. Always ensure the power is off before removing the fuse.

FAQs & Answers

  1. What setting should I use on a multimeter to test a fuse? You should set your multimeter to the continuity or resistance setting to test a fuse.
  2. How do I know if a fuse is blown using a multimeter? If the multimeter shows no reading or infinite resistance, the fuse is blown and needs replacement.
