How do I test a wire with a broken multimeter?
Keeping this in view, how do you test if a cable is broken?
Test for a potential open circuit by using one multimeter lead to touch one of the prongs on the AC side of power cord. Use the other lead to touch one end of the console side of the power cord. If there is an adequate electrical connection, the multimeter will beep.
Also, how can I test a wire without a tester? For example, get a light bulb and socket, and attach a couple of wires to it. Then touch one to neutral or ground and one to the wire-under-test. If the lamp lights, it is live. If the lamp doesn't light, then test the lamp on a known live wire (like a wall socket) to make sure it actually lights.
Keeping this in consideration, how do you check continuity on a long wire without a multimeter?
Re: Testing continuity in a very long wire The meter will need to have a good battery. Set the meter to the lowest ohm range (resistance). Touch the probe ends together; you should read zero ohms (no resistance). Now use the meter probes (ends of the wires) the same as you would a test bulb.
How do you know if you have a bad wire in your house?
Feel for Warm or Vibrating Wall Outlets Another way to find out if the wiring in your home has gone bad is to check by feel. Without touching any wiring directly feel your home's electrical outlets for heat or vibrations. In the case of either, have an electrician check for and replace any loose or damaged wiring.
