How to Repair a Light Switch Circuit
How to Locate and Repair Faulty Electrical Wiring for Lighting: Secrets of Successful Electrical Troubleshooting Methods used to solve the majority of the home electrical problems.
Locating and Repairing Faulty Electrical Wiring
[ad#block]Electrical Question: Three different light switches in three nearby bathroom areas will not work but the switch adjacent to the light switch controlling the fan will work on all but one.
- I checked the GFI box and none were tripped, I even reset all applicable ones.
- I checked the circuit between the switches with a current tester and neither light switch was getting a signal.
- Two of the switches that controlled the fan had a strong signal but one of them gave a very weak signal. All electrical outlets in each of the room are fully functional.
- There must be a fuse between all three light switches that has blown and I don’t have a clue where to find it.
Any input would be greatly appreciated.

Thanks for your electrical question Robert.
Repairing Faulty Light Circuit Wiring
Application: Troubleshooting and Testing Light Switch Circuit Wiring.
Skill Level: Intermediate to Advanced. This electrical repair project is best performed by a Licensed Electrical Contractor or Certified Electrician.
Tools Required: Basic Electricians Pouch Hand Tools and Voltage Tester or Continuity Tester.
Estimated Time: Depends on experience and level of problem solving skills.
Precaution: Testing live wires is dangerous and should be done by an experienced individual only. Testing using a continuity tester should only be made after the circuit has been identified and turned OFF and Tagged.
Several Light Switches Do Not Work
- From what has been described I don’t believe you will find a fuse problem, however I do believe there is a problem with an electrical splice or connection which is commonly found either in the switch box or in a fixture box where the power my be spliced through leading to the affected areas.
- The electrical wiring and splices in the switch box should be inspected for burnt and damaged electrical wiring.
- Necessary electrical repairs and replacing affected wiring must be made to ensure proper connections and circuit integrity.
