Topic: Installed led blinkers and now they quick blink. Is there a fix?

[rmoore]

Since I installed the led blinkers, they now blink fast like one of them is out. I understand the basic premise of this.( Lower voltage use and the system thinks its a burned out bulb). But does anyone know how to fix this. Different flasher? Im sure Im not the only one that is driven nuts by this. Any help would be appreciated. Thanks, Ryan

ya U need to change your flasher relay.  i believe there called electronic flasher relays.  your local napa or who ever have them   

[rmoore [OP]]

So after I posted this I finally found an older post talking about a fix. But it was only on first and second gens.  Has anyone done this resistor clip mod on the 3rd gens?

IIRC you need about a 50w load to get back to the normal wattage for the filament...

you can also find them at your local truck stop....

Blinker fluid is low
A led has little or no resistance, compared to a filiment bulb. So thats why it blinks at twice the speed.

wow learned me something new.

[bleakhorizon]

oh yea, and an electro mechanical flasher unit works too..

i think the grote numbers are 44820 for the round two pin style and 44530 for the square two pin style.. (those numbers might be backwards or old numbers too) been a while since ive looked up electrical

No new flasher needed. Just cut the trace on the circuit board for the "bulb detection"

I think there's a thread on yota tech. Takes 5 minutes and no money. Does the same thing as an electronic flasher

Here is a listing for a bit cheaper and it's from AGT who makes the best SMD bulbs I've used yet: http://www.amazon.com/gp/product/B0077CSW04/

This is a GREAT idea! I'm going to look into this, thank you!

I'm going to look into this

Here is the thread in question: http://www.yotatech.com/f2/cheap-bastards-idiot-guide-fixing-fast-blinkers-after-led-swap-80626/

My wheelin partner installed some LED's and didn't like the fast blinking or the resistor fix so......this is what he did. Thought I'd share with yaul.

The relay that needs to be modified is well hidden. You will have to take down the lower part of the dash and remove the two bolts n the picture below:



Once you have those removed you can wiggle the box down. The arrow points to where the relay should be, the relay had already been taken it out when the picture was taken.



Here is what the unit looks like:



He is lazy and rather than scraping the solder off that terminal he just drilled out the red spot in the pic below. This is the "Lamp Failure Detection" pin according to this link, page 3.  http://www.atmel.com/dyn/resources/...nts/doc4727.pdf



 
After you drill it out, just put everything back together and you’re done.
FWIW: the truck this was done on is a 1999 TRD model, and the label on the top of the chip is U643B.

Hopes this helps. Easy mod and only took about 10mins once he found the relay.

If you have ?'s you can mail him direct at sloth@r65.org

That's it! I didn't remove the dash. I just lasted on my back, reached up, and pulled the flasher. I noted which way it went.

Instead of drilling the pin, I just cut the trace and scraped away a small section using a razor blade

Or if you don't trust yourself, you can get the Tridon EP-35 flasher.

Saving this thread for future reference.

huh.....stupid new age bulb detecting relays lol
