How to Test a 15 Amp Fuse Using a Multimeter

Learn the simple steps to test a 15 amp fuse with a multimeter and identify if it is blown or still good in your electrical circuits.

744 views

To test a 15 amp fuse, use a multimeter set to the continuity mode. Remove the fuse from its circuit and place the multimeter probes on the fuse terminals. A continuous beep or a zero reading indicates the fuse is good. No beep or a high resistance reading means the fuse is blown and needs replacing.

FAQs & Answers

  1. What does it mean if a fuse has no continuity? If a fuse shows no continuity on a multimeter test, it means the fuse is blown and needs to be replaced to restore circuit functionality.
  2. Can I test a 15 amp fuse without removing it from the circuit? It’s best to remove the fuse before testing to avoid inaccurate readings caused by other circuit elements.
  3. What setting should I use on a multimeter to test fuses? Use the continuity mode on your multimeter, which typically beeps or shows zero resistance if the fuse is good.
