What happens here

To check a simple wire for breaks, place one multimeter probe on each exposed end of the wire. If the wire is intact and continuous, the multimeter will beep. If there is a break or damage within the wire, the multimeter will remain silent and show 'OL', indicating no electrical path.

Goal: Verify an electrical wire's integrity.

Tools and materials

  • Multimeter Klein Tools MM400 — To test the wire
  • Multimeter Probes — To contact the wire ends
  • Electrical Wire — Demonstrating continuity on an intact conductor

What they say

And your switch is on, you can hear the beep. Well, when I turn that switch off, the beep goes away. Switch on, there's a beep. And a wire, obviously, will will sound the beep as well. If there were a break in here, it wouldn't. That's how you test for continuity. I like to use this on fuses most of the time in the car or on my furnace when I can't see or whatever else has fuses,
