LED Indicator Lights

Just installed new LED's all around. All 4 indicator lights flash regardless of turn signal position (left or right). Saw the earlier post on this and I do have an adjustable relay. Just added 2 resistors to the front indicator lights and they all still flash. Do I need to add two more resistors to the rear indicator lights? This seems like a belt and suspenders? Thanks for any help.

This is nothing to do with resistors

Remove the front resistors. The variable relay takes care of that requirement. Sounds like an issue with the hazard switch. Gently pull it towards you. They get a bit sticky and don't release properly and no doubt you've pressed it testing the lights.

No Joy

Thanks Jason, but I just removed the resistors and gently pulled the hazard switch to no avail. Perhaps a bit more force, say a 10 lb sledge, might be better? This isn't rocket science, but clearly I'm too close to the problem to see a rational solution.

No problems before the switch to LEDs?
Step at a time with electrickery:
To confirm the relay is working correctly, put the old one back.
If no change, then we also know that the problem is elsewhere.
Any other electrical work performed at the same time?

This might be a long shot but perhaps your black and red are reversed; meaning for some reason your common going back is hot and your hot goes to ground... Maybe something in the harness, hook your meter up and see if the polarity is reversed with the lights on

Edit this is probably incorrect having read the symptoms in more detail but I'd still check. Sounds like some interesting wiring might be causing your headache

My issues with LED installs were with jerry rigged wiring by the previous owner and incorrectly wired Wipac LEDs from the factory.

^^ what he said ^^.
Incandescent bulbs are not dependent on polarity to work. However LEDs (D as in diode) are.

I had a similar issue. See thread: http://www.defendersource.com/forum/...ad.php?t=51910. I had the adjustable relay and was not supposed to need resistors all around. That did not work. I added resistors all around and it worked like a charm. Not sure why - could be magic. The link to the resistors I used is in the thread. good luck.

Do you have marker lights hooked up or LED there as well?

Usually markers are enough resistance when used with the adjustable relay.

that could have been my issue, because I have LED bulbs in my marker lights as well.

Thanks

Mybluett solved the problem. One of my marker light bulbs was not working!!! Fixed the bulb and all is well in the world. Thanks to all for their thoughtful suggestions.
