Technical LED Turn Signals Not Flashing

I bought some LED lenses for my latest build. They go in 36 Ford style tail lights, like this.



The brake and tail lights work great. I bought an Electronic flasher unit like this...



Turn signals work fine with the key on, but once you start the engine, they don't flash. I just get a solid light, no flash.

I have a universal turn signal switch like this...



and a 12V system, using a 57-64 Ford 30A generator.

Any ideas?

Thanks,

Neal

 

My guess would be that the LED's don't draw enough power to activate the flasher. Try putting a regular bulb in the circuit and see if it works. You may have to add a resister to the circuit to draw some power.

I tried some 32 leds like you have and it wouldn't work with the LED flasher,I put the old flasher in and it worked like a champ. HRP

 

Perhaps you need an Led load resistor , or a regular bulb in the circuit , to make enough load for the flasher to realise there is somebody home at the end of the wire.
Possibly when only the key is on there is load on other components to reduce load enough to allow flashers to operate, but once the charging system is doing it's thing the load reduces and the led lights fail to operate.
I have to admit while LEDs are not traditional they sure work great. I use them in all my rods now.

 

Definitely need an LED flasher or a regular bulb in the circuit for resistance I picked up a spare LED flasher just to carry with me Jim

 

Try a 6 volt flasher

 

You need what is called a no load flasher. LED lights don't have enough resistance for the flasher to work. Most good parts houses have them or can get them

I thinks the car is revolting against the LEDs.

 

Did you hook the black wire of the new electronic flasher to ground? This needs to be hooked up!

 

you have a open ground somewhere in the wiring check the flasher can first . then move to the switch .

 

Oldsman and Kiwi are on it. Because LEDs draw so little current you have to use a load simulator or resisitor to trick the flasher into thinking there is a bulb in the socket. Some newer LED bulbs have the load resistor built in, others you have to add it. Easy fix and dirt cheap for once.

 

The electronic flasher does not need a load. But it must be grounded for the circuitry to work. Leds were the primary reason for the electronic flasher being produced.

 

Who are you, and what have you done with Neal?
