turn signals won't blink!!!!!!

All right, I have a self imposed problem. Took the '28 Es*** apart for paint 2 years ago. I have tried re-wiring the turn signal to no avail. The blinkers will light up, left and right, when turned on, but won't blink. Checked the turn signal fuse, that's OK.
Any thoughts.
I have changed the flasher module
Emergency flashers work.
If the blinker module was bad, I wouldn't have power to the turn signals.
The power fuse is good.
Help

LED bulbs will do that. They don't draw enough current to trigger the flasher module.

 

Thanks for the reply.
The front and rear lights are LED. I have installed an LED flasher module. Where do I go from here?

 

Circuit is complete, or else the bulbs wouldn't light up.
Quick check would be to add another bulb to increase current flow and see if this triggers the flasher module.EDIT: using jumper wires.
Parts cannon would be to just replace module, since circuit is complete, lights work and the module isn't doing it's job.

 

Change the bulbs to halogen…I’ve thru the LED fiasco. Some guys have been successful with only one bulb change. I think they kept the rear as LED

 

I did a re-wire on a 442 and had the same problem. It had LED bulbs front and rear and an LED flasher unit. I called the company that made the wiring kit and they told me the LED flasher units were a bit flakey. They sent a new unit and it worked fine.

 

Does the LED flasher module have the ground pigtail on it, or is it one that is suppose to have the internal ground?
I had to put one with the ground wire on my truck to get it to work properly.
Since both sides light up and turn off with the switch, the issue involves the flasher, its the only thing that makes the light blink off and on in the circuit.

Just because the part is new, that no longer means the part is good. Lots of junk new parts are out there these days.

 

Yep, helped a guy troubleshoot his turns with LED lamps and it was a bad flasher. Look for a USA-made one...

 

Did you check if the parking light and turn signal wires are not crossed? If they are parking lights will be really bright on LED’s, keep in mind with the parking lights on the turn signals will be brighter as they flash…..

 

Needs a new flint.

 

Right now, if it has sockets that you can put 1157 bulbs in without a h***le I would stick 1157 bulbs in it and see if it all worked. Then you will be able to tell if it is the LED lights not having enough resistance or a wonky flasher.
My experience (not good) says that there is a huge disparity in quality when it comes to electronic flashers.
They do sell resistors to put in the lines to the turn signals that a lot of guys are starting to use.

 

I've read on one forum of using an 1157 bulb inline to create the resistance needed, or placing a resistor inline for the same result. When my lights did the same I called the flasher manufacturer who advised turning the flasher 180 in the socket. It worked!

 

The problem with LED lights is they draw very little current. Putting a resistor inline would make matters worse. Putting a resistor in parallel might help the problem if it is low current draw.

 

I cured that problem by simply changing to non-LED bulbs to my dash blinker indicators... gave just enough resistance to make my LED light s work.

 

Sometimes, even a LED compatible flasher won't do it. Some 50 watt 6 Ohm resistors will make it happen.

Good luck!
