LED Turn Signal Stumper

[Buckn]

Starting to smell the finish line on my 2-year project. I've installed the Painless Harness, LED's all around and LED Flashers. My Hazards work fine but the turn signals don't. I've confirmed my wiring is right and jumped the Turn Signal Flasher and can operate each side turn signals at the steering column though they stay on constantly since there's no Flasher in the circuit. This made me think I had a bad Flasher so I swapped it with the working Hazard Flasher and get the same result. Has anyone had this issue or have any ideas?

Try replacing both front or both rear lights with incandescents as a test. See if they work then.
If they work with one replaced then you know that the problem is likely the low current draw of the LEDs. Can go to resistors in parallel to increase the current draw or try a different flasher.

Thanks ntsqd... I talked to the guys at Wild Horses this afternoon. They told me the LED flashers are polarity-specific which I didn't know. I looked at which side of the connector was hot for my Hazards and the Turn Signal connector in the Painless Harness was wired the opposite. I just got done switching wires at the connector and Wild Horses was spot-on. Got blinkers!

Yay! A win.

When replacing things with leds I had to run incandescent bulbs iin the front to make it work, I wanted the back break light to be brighter
fine after that

Some LEDs are specific, others are not. Only takes a swap of wires to find out. Good thing to know and remember.
