Fast Turn Signal
 

To start, I have already searched the many threads that deal with this issue but can't seem to find an answer.

All of a sudden my front left blinker on my ARB bumper has stopped working. Because of this, the rear blinker is blinking twice as fast. I have tested all of the bulbs, front and rear, and I have checked the turn fuse. Nothing seems to be bad. I then tried the emergency lights and the blinker still doesnt work. The weird thing is that the blinker has twice, randomly started working for a short period of time. I checked the bulb socket to the turn signal and it is getting only around 3-4 volts of power.

What should I check from here?

Hopefully this thread will be informative so others can use this in the future.

Thanks in advance!

sounds like a short in a wire to me...

Loose connection? Shorted wire?

Check the ground connection for the bad light. Make sure it is connected to bare steel.

how old is the bumper?? I had the same prob wit my arb. the ground prong in the socket rots apart u cant see it till you pull the socket apart. i soldered the ground wire farther up on the grond prong of the socket, and will soon order a new socket but it works for now.

I had a similar problem where my front left turn signal would blink very fast. The bulb worked, but it would just blink fast. Not knowing what else to do, I replaced the bulb and everything is fine. Don't know why. I can only guess that bulb wasn't getting a good connection. If you have a spare bulb or two, you might want to swap it out just to see. Worth a shot.

Thanks for getting back to me. I will check what ya'll recommended sometime tommorrow.

I tried swapping the bulb from the working one on the right to the left one and it still didnt work.

Does anyone know about relays and think this may be a cause?

Sorry it took so long for me to post back. I ended up undoing some of the wiring I had done and found that water had gotten into a crappy taping job I did around some connectors. I let it dry out and retaped and now it works fine. I guess I could have soldered the wires together but I didnt have time. Thanks for all the suggestions!
