Wiring Gremlin in Turn Signal

[bdavis]

I have a wiring gremlin. My truck was rewired about a year ago and worked flawlessly. I took the front grill and hood off to paint and have put everything back together. Now my passenger turn signal will not work when my driving lights are on. Infact, it kills all the lights on my right side including the rear lights. The signal works fine without the lights on. Any ideas what it could be? I did not mess with any of the wires so i am guessing its a ground somewhere.

Sounds like your ground is not making contact. Probably the new paint, you need to scrape the paint off where the ground wire bolts on.

are you talking about the ground from the turn signal lights. I have tried a jumper wire grounding the turn signal to the neg on the battery and still had an issue.

How do the running lights, hazards, turn indicators and brake lights work?

I just fought these. Try checking all your light grounds. I had rear cups and front parking lights with insufficient grounds. Made good grounds and now everything hunky dory.

Also check the bulb connections. I found that there was debris limiting the bulb ground to housing. I cleaned it up and tightened the bulb socket sides.

Even though you used a jumper wire to the battery (good idea actually), it may not have been enough in your case.
With all the new paint, your entire core support might be completely isolated (ground-wise) from the rest of the system.

You can isolate the light assembly as the culprit though, by running power and ground to the wires of that light only, leaving all others out of the loop, to see if it still runs funky.
Sockets can get corroded and lose good contact with the bulb. Socket contacts can wear down over time. Wires can become disconnected from their contacts inside the sockets and connectors. All sorts of stuff like that. But with new paint being the most recent change, I'm still leaning towards the ground issue.
To "fix" it, you may end up running a separate ground circuit from the main body to the core support, and grind the pain off of any and all contact points directly mounted to the support.

Again, even though you did perform a normally conclusive jumper test.
Good luck.
