Troubleshooting Trailer Interior Lighting that Turns Off and On Intermittently
Question:
Hi Not sure if I have a short. Lite in kitchen will turn Off and come on when it wants too. It is powering 4 other lites, that also go on or off by their self, when the switch is on. I checked all 15 amp and 25. Amp fuses, with the lite on, pulling them, the lite didnt go out. Where would the power source come from.

Helpful Expert Reply:
The problem is an intermittent connection either on the power or the ground wire. There should be a battery somewhere in the trailer that draws the power for the lights. What you can do is check the power wire of the light when it is turning off and on with a circuit tester like part # PTW2993. If the power stays constant when the light goes off then the problem is a bad ground.
If the tester shows the loss of power when the lights go off then you know the problem is on the power side. Either way you will have to trace the wiring back in either direction to find where the bad connection is.
