Replacing Power Cords

By: James Marshell

When your power tool stops working there could be many reasons behind it. It can be the motor, winding, switch, carbon brush among other things that might have gone bad. But sometimes all it takes to stop your power tool from operating is a bad power cord. Power cord may get damaged because of various reasons.

When your power tool doesn’t operate the way it’s supposed to, check whether power cord is fine or not. If it’s not conducting electricity properly then the fault isn’t with your tool, instead it’s in your power cord. You can check the conductivity of the cord with a multimeter or a continuity tester.

Remember, if the power cord is damaged or cut, don’t try to turn the power tool on as it can cause physical and/or property damage in the form of electrocution and it may render your fine tool completely useless.


Once you have ensured that the problem lies with the power cord, you need to replace it to make your tool work again. You can get the similar cord from retail or online stores where superior replacement parts are available. If your tool is from a familiar brand like Wilton, then you can easily shop for Wilton replacement parts on the internet.

The tools you will need to replace the bad power cord with a new one include:

• Screwdriver
• Utility Knife
• Wire Stripper
• Pliers
• Multimeter or a Continuity Tester
• Masking Tape for insulation
• Replacement Cord

Before starting the replacement process, make sure that the power tool is unplugged and is turned off. Also ensure that the area where you are working is clean and free from unrelated stuff that might clog or cramp your power tool. Here is what you’ll need to do:

1. First of all you will need to uncover the terminals of the wire. In majority of the power tools the wire terminals are directly connected to a switch that sits behind the trigger.
2. Disassemble the tool so you can see the inside circuitry.
3. Find out the part where wire is connected to the terminal and unscrew the wire. Usually these screws are very small so you will need a small screwdriver. Pull out the wire from the terminal. Remember to observe the path between the terminal and the switch because you will have to introduce the new wire through the same path.
4. Mark the terminals with the masking tape so you can connect the right wires with the new cord. Note that three-pin plugs usually have three wires and two-pin plugs have two wires.
5. Find the retaining bracket and remove the old cord from the tool. You may need to unscrew the retaining bracket.
6. Now, remember to get the correct type of wire for your tool. Wires vary according to amperage and voltage and sometimes even length. So having a correct wire is very important.
7. If your wire came stripped then you can carry on with the installation of new cord but if it is not stripped use the pocket knife to strip the wire. Use wire strippers to strip the insulation away. Half inch would be fine but if you want to be sure then compare it with the bad wire you just removed.
8. Recheck the masking tape indication on the damaged cord, in order to ensure the correct connection of wires. Now, place the new wires in the accurate route to avoid pinching the wires Secure the power cord in place by screwing back the retaining bracket.

At the end, reassemble the plates of your power tool and check whether everything is safe and fully functional. To check the safety, use the continuity tester.
