Guys:
I hope someone has an idea, cuz I am outta them. My running lights don't work.
Coming out of a 7 slot thru an adapter to a 4 flat. The wires were frayed on the trailer, insulation worn off and blew the fuse in the Explorer (tow vehicle) for the running lights. Fuse replaced. A-OK.
Cut the wires, wired in a brand new 4 flat pigtail and used butt joint heat shrink connectors ( they are great). Hooked everything up, including new Ground line. Checked continuity on each line with VOM (old analog Radio Shack - still works). Everything checked out OK, including Ground continuity.
Plug in the connector. Left Turn Signal (yellow)- Perfect. Right Signal (green). - Perfect. Running lights - (brown-green and brown-yellow) - Nothing. WTF???!!! BTW: Running lights and turn signals use a common ground out of the light socket.
Ok. VOM goes to the DC voltage scale. Test the voltage out of the vehicle 4 flat adapter. 12V on all three lines. I expected the turn signals since they worked, but didn't expect the running lights voltage to show up. Pulled the light off the trailer and wired up a jumper to make sure the light worked. Yup, perfect. Went back to that taillight socket and I only get 5v???!!!
So I cut out 1 of the butt joints and I still only get 5v.
So, somewhere between the vehicle and the brand new pigtail that I wired in, I am losing voltage. How is that possible?
If no one has any ideas, my next step will be to cut out the butt joint connectors I used and use a jumper wire directly to the 2 brown lines (running lights) already in the trailer, bypassing the new pigtail to make sure the lights do in fact work and I don't have some other issue.
Thanks, in advance, guys, Any ideas?
