    None of my turn signals work. So I proceeded to check the Junction box on the rear of the tractor. When I use a test light, I touch one of the wires and they start working. This has got me really confused. I've cleaned and used electrical grease on all connections but can't figure out the problem

    If you ground it with a test light and it works than I would check the ground connections. Do they work on t he tractor?

    ...so the problem first occurred when you switched from incandescent bulbs to LED? That sort of info should have been included in your 1st post...otherwise, nobody would've guessed that. I was under the assumption that they were working and quit...and that you were trying to figure out what had happened, NOT that you were modifying things and messed up somewhere along the way.

    Good help requires good information.
