Ok everyone so I need some opinions. I just replaced my trailer wiring and everything was working great for a couple weeks until now. I tested the plug coming out of my truck with a circuit tester and it all works. When I have the "not installed" wiring in the back of my truck grounded to my truck and plugged into the connection im able to get a complete circuit at the end of the wires (without the lights connected). When I connect the lights I get nothing from them. I have tested them with a battery and they do light up. Soooo....my questions.....
Will the plug from my truck give a false positive if I have the alligator clip from the circuit tester attached to the truck? I didnt think so but im trying everything....
Would the trailer lights have to be mounted in order to have a ground even though the trailer wiring harness has a connecting ground coming from the plug to the trailer?
Im sorry if this sounds simple. Im not well versed in electrical circuits. When I initially replaced them it was easy and worked right off the bat but this troubleshooting is driving me crazy. Thanks in advance!
