Power outlets not working
I had a problem with 1/2 of my trailer outlets not working. After a lot if line continuity testing I found the problem. To make checking easier I used an extension cord from each outlet back to the breaker panel. Don't forget to disconnect the main power. Disconnect each wire and check continuity to the extension cord outlet. Found 1 black wire was not connected???
Removed the socket, pushed the 4 tabs on the plastic cap on back of the socket to remove the cap and yippee. One loose disconnected wire. I was not impressed with the connection type. No screws. Just push the insulated wire between 2 blades and hope it stays there. Pushed the wire back in and all outlets now work. It was the outlet closest to the panel. You'd think with all the vibration the trailers are subjected to there would be a more secure connection.
It was not an easy problem to diagnose but hopefully this helps other. Photo attached.
