How to Fix Torn Electronic Wiring Components


You can mend a torn electronic wiring component by soldering the ends of the broken wire back together. There are many ways to temporarily mend a torn wire, but you can make the repair permanent by soldering it. Wires, in their simplest form, conduct electricity. In order to get the wire to work again, it needs to conduct electricity through itself. Soldering reconnects the wire through a conductive substance, which won't disrupt the flow of electricity through the wire.

Things You'll Need

  • Wire cutter
  • Wire stripper
  • Soldering iron
  • Solder
  • Scrap metal
  • Electrical Tape

How To Fix Torn Electronic Wiring

  • Turn off, remove and unplug all electrical sources for the device with the torn wiring.

  • Completely separate the torn wire by cutting it apart with the wire cutters.

  • Cut off any damaged part of the wire.

  • Strip the wire shielding down from each end of the torn wire so that enough metal is exposed on both sides that they can be twisted together. Depending on the thickness and flexibility of the wire, you may need to expose anywhere from 1/8 of an inch to 1/2.

  • Twist the exposed metal part of both ends of the wire together so it is firm enough for you to gently tug on the wire without it coming apart.

  • Plug in the soldering iron and let it heat up.

  • Remove approximately four inches of solder, fold it in half and twist it together like a simple braid.

  • Press the tip of the heated-up soldering iron against the exposed part of the wire with one hand. After a few seconds, press the tip of the braided solder against the heated part of the wire, not the iron. The solder will melt in and connect the wires.

  • Wrap the mended wire connection with electrical tape so that there is no exposed metal.

Tips & Warnings

  • If possible, try to work on a flat, elevated surface like a table.
  • When soldering torn wires together, try to not connect any additional conductive parts of the device to the solder point, because it can break the circuit and cause the device to stop working.
  • If the repair will make the wire too short, you can connect the two parts of the broken wire to a wire of similar diameter.
  • Wipe excess solder off the iron with a piece of scrap metal.
  • You should make sure there is no electricity running through the device you are repairing. If you can't unplug the device, try turning off the circuit breaker.
  • Don't work on devices that have large capacitors unless you have specific training to work on that type of device, because they can hold an electrical charge for a long time. Some devices can hold a fatal charge for long periods. You can seriously injure or kill yourself.
  • Work in a well-ventilated area and avoid breathing in smoke or vapors from soldering.
  • The soldering iron can become hot enough to burn you and ignite flammable objects.
