Sorry if this gets lengthy, but I'll try to explain the chain of events as best as I can.
I recently did the tube fenders on my Jeep. I am using a little 2 wire LED for the turn signals like countless others have. I tested out the lights without permanently installing them and they worked, apart from the rapid flashing that was expected to happen. According to the seller of the LEDs, this would be fixed by replacing the stock flasher unit with one of these: LED Flasher Unit 5 Pin TJ LJ 2001 2006 | eBay
So I ordered the flasher. Here is were my stupidity starts to shine. Due to me needing to paint the fenders and not wanting to mess with the turn signals before doing so, I ran without front turn signals for a week or so. It was fine until one day I noticed my signals didn't work at all. When I hit the stalk, nothing happens on the dash or the lights. The only thing that gets any kind of action is when I turn the headlights on, the right turn signal indicator comes on steadily on the the dash, but the light doesn't actually come on the outside. Things get even weirder. I can get the light to turn off
on the dash by hitting the stalk up (which would normally activate the right turn signal).
I looked around for a cause, and realize that in my rush to get the Jeep back on the road, I left the left turn signal wires bare. At some point, they must have touched, and messed something up, right? Because I just replaced the flasher unit and it didn't fix the problem.
