Use wire strippers or a utility knife to remove the stripped off broken plug. This will expose three groups of needle-thin copper wires.
With your utility knife slice an inch down the rubber covering, giving you unfettered access to the three wires. Pull the three wires away from one other.
Cut the jacket and insulation from each wire group with a pair of wire strippers. Expose about an inch of the copper wires.
Take the new plug and remove the screws holding it together. Inside the plug find three screws, gold silver and green. Loosen each one, but do not remove them.
Connect the new plug to the existing extension cord. The wire with black insulation slides under the gold screw. Tighten the screw. No stray wire should be exposed beyond the screw head. The white wire fits with the silver screw, and the green wire with the green screw. Tighten all screws.
Put the two halves of the plug back together and re-secure with the screws.
Plug the new end into an outlet and test.
Things You Will Need
- New plug
- Utility knife
- Wire stripper
- If the extension cord still does not work, there may be cuts in the wiring at any point along the cord. Check the cord carefully for cuts, scrapes or exposed wiring.
