1978 T1750 clearance lights
Ugh. I installed new tail lights today on the trailer and was really happy to find new replacements for the old style square lights. They look just like the originals! However when I tried to light them up by hooking up to the truck via the 7 pin, I had no tail lights, just stop and turns. I chased the wiring, inspected the wiring harness, checked fuses, ugh! Finally I found it. Bad grounding, (and bad connections in general) in just about ALL of the clearance lights along the upper front and rear of the trailer had caused a lot of resistance which melted a ground wire right off one of them.
So looks like I’ll have to swap out all the clearance lights for some LED jobs off Amazon this week. Sigh, one problem leads to another!
Thanks for letting me vent. Happy camping!
