How to Test a Light Socket

1
REMOVE MOUNTING SCREWS TO TEST FOR CURRENT
Remove mounting screws test current - Testing Light Socket

Remove the mounting screws, and carefully lower the socket. To test for current, touch one probe of the circuit tester to the hot screw terminal that's attached to a black wire. Touch the other probe to the ground screw, the bare copper wire, or the metal electrical box. Repeat this test with each of the other screw terminals. If the tester doesn't glow in any position, there's no power coming to the box.

  • Turn the power off to the socket.  
  • Test the socket by attaching the clip of the continuity tester to the hot screw terminal, the black wire lead. Then, touch the probe to the metal tab in the bottom of the socket.  
  • The tester should glow. If it doesn’t, the socket is faulty and needs to be replaced.

CONTINUE TESTING THE SOCKET

  • Continue testing the socket by attaching the clip of the continuity tester to the neutral metal screw terminal, the white wire lead. Then, touch the probe to the threaded portion of the socket.  
  • Again, the tester should glow. If it doesn’t, the socket is faulty and needs to be replaced.
