That is what is stumping me Vette. Right tail light is bright, left one is dim. And also left marker comes on also dim. All the other features like brake lights and parking work perfect. Only when I hit the right turn signal does the left one join in on the fun dim-ly....
I thought I was going crazy. This ended up being a frame off, so I relocated battery to frame. I ended up building my own PDU up on the core support and I ran everything back through 1/0 awg wire straight to battery. Everything is painted included frame so for the tail lights I went ahead and ran a ground from frame to rear cross member. I thought maybe from rear cross member to bedsides the paint was causing an issue but I took a wire from my frame ground and manually ran it up to the bedsides. No change.
Tell you what though, I painted the tail light buckets too and just relied on the screws to eat through the paint on both the bucket/socket and the bedside clips they screw into. I will just have to take the lights back off again and test them like you said. I will report back tomorrow.
And franken, I went through that thread thanks for the response.
