How to Identify Electrical Wiring Problems with Outlets

Application: Troubleshooting and Repairing Outlet Problems.
Skill Level: Intermediate to Advanced – Best performed by a Licensed Electrician.
Tools Required: Basic Electricians Pouch Hand Tools, Voltage Tester or Volt Ohm Meter or plug-in circuit analyzer.
Estimated Time: Depends on the age of the home and the condition of the electrical wiring and access to the circuit wiring to be inspected, evaluated and repaired.
Precaution: Identify the outlet circuit at the electric panel, turn it OFF and then Tag it with a Note before performing any wiring inspections or electrical repairs. If an outlet or the electrical wiring is found to be damaged then repairs and replacement parts should be obtained with the same voltage and amperage rating.

    Hi Jace,
    It would be good to test the outlet with a plug-in analyzer to see what the readings are. Depending on how you are testing the outlet, it may appear to have power, but it could be that the neutral has lost it’s connection within the circuit. Without the neutral devices will not work. Review the troubleshooting tips in the above article for more assistance.
    I hope this helps,

    We had a bad outlet outside. We repaired it with a new one and we are still not getting anything when we plug something into it. So we tested to make sure it had current going to it and it does but when you plug into it nothing works. Just wanted to see if you had any suggestions, we are lost for words.

    Thanks .

    Hi Dale,
    Troubleshooting a GFCI Outlet Circuit
    From what you have described, when you removed the faulty GFCI outlet the circuit electrical wiring which supplied power to the other lights and outlets has become disconnected. Therefore a replacement GFCI outlet must be installed to continue to provide important ground fault protection to the circuit and in turn provide the circuit power which has been disconnected to the other affected devices.
    Be Safe,

    I had a GFCI outlet that quit working. The outlet was bad so I removed it. Now lights and outlets in part of the house do not work. I’ve checked the breaker and it wasn’t thrown and does have power going through it. When I test the wires coming to the outlet, I have no power. What’s the next step?

    Hi Don,
    I agree, the circuit breaker should have tripped off when the trimmer cord was cut. I would check the circuit breaker to make sure it is sized properly for the circuit wiring, and if the breaker appears to be correct then consider having the breaker replaced it with a new one. You may consider either replacing the circuit breaker with a GFCI breaker or install a GFCI outlet at the location the cord was plugged into. GFCI ground fault protection is of utmost importance when using electrical equipment outside.
    Be Safe!

    I cut the extension cord to my hedge trimmer and it was sparking, yet continued to run. I unplugged the cord at the outlet. The wires were severed and the hot (black) wire was fried and the insulation was cracked and brittle up to about 4 feet from the trimmer. The breaker did not trip. I checked the wiring to the outlet and used a circuit checker to confirm. It tested correct (both yellows lights, no red) I’m puzzled as to why I did not trip the breaker.
