Anyone do the blinker-relay mod as per http://www.stu-offroad.com/electrical/led1/led-4.htm ??
I was at B&E, picked up a similar relay, with different pinout.
I got my flashers to flash normally (say that three times fast).
But the dash indicator for the arrows comes on when I turn on my lights. As if to tell me I have a bulb out.
Can anyone verify this behaviour? Or have I mis-soldered something?
Cheers
Chris

You can buy flashers if u have led tail lights.
I bought one for the jeep. plug it in and its done. works like a charm
I wouldnt wasted your time trying to modify..

Do you have a part number and location where I can get this said flasher?
And does it work in an 01 and newer tj? With the integrated relay/flasher module?
Thanks

Interesting. Probably not seeing the correct resistance. We get this all the time on motorcycles that have removed the stock signals for LEDs.
t's a simple fix, wire in some resistors. Depending on the stock bulb wattage, a 20W-8ohm resistor (or a series pair of 10W-4ohm) resistors wired in parrallel to the LEDs should do the trick. Assuming about a 27W max load (1157 stock bulb). Use your Ohm/Watt's laws from high school to figure out the proper resistor for a different load.
Of course, a HD flasher is a lot less work if you can find one! :D

Don't put in the resistors they add heat and currunt draw to the system
I did my led install and flasher mod on Sunday and everything works just like stock
I don't think there is a flasher avalible for the 2001 and up tj to correct for Led lights
Chris
Sounds like u mis-soldered something
this is the link for the flasher mod that I followed

If u still have problems let me know

Where did you get the relay Steve? I have tried to find it at RS but they told me they didn't carry it anymore.

Vince I got one at Active on 32nd I can't remember the part # but I can stop in on thurs and get it
the specs on it are
coil 12v
contacts 1A @24V
DPDT
aprox sixe L3/4" * H1/2" * D3/8"

After asking the sparky at work, I have mis-soldered mine.
I got mine at B&E on Manitou Road 24VDC/3A SPDT, 15.7mm x 10.9 mm x 12mm, three bucks something.
I have the pinout and schematic to solder it up, for those who couldn't read a circuit diagram (ie me).
About to re-solder now, I'll let you know how it goes.
Cheers

Chris is the coil 12V?

Chris is the coil 12V?
Not sure, the datasheet doesn't tell me, or I don't know how to read it.
The relay says 12VDC, 3A 125VAC
The method I'm using is the same across both links above, same pictures and writeup, just different sites.
OK, I'm not a circuit analysis kinda guy, here is a ghetto schematic of the relay, how would I wire it up???
-------------
pin#1 |o -- --o| pin #2
| / |
| | |
pin #3 |o--coil---o| pin#4
| | |
| | |
| | |
pin #5 |o ------- o| pin#6
-------------
Dang forum software is not making my spaces into spaces, anyways the schematic is on the link. I'm sure you can figure it out.
I had ign to pin #3
pin#4 jumped to pin#2
pin#2 to ground
ping #6 to sw
And I get normal flash frequency, but on dash indicators lit.
Datasheet is here http://www.songchuan.com/PPDF/842.PDF
regular 842 type
Thanks

You guys sure make a lot of work for yourself... buy this, buy that, solder this, etc
Just buy the led flasher and plug it in. Took me 1 minute. Done.

As far as I know, there is no off the shelf LED flasher for the newer TJ's
-
I should have kept the box. Cost like $15 bucks
Its a blue module that plugs into the flasher socket.
-
And now it seems I've pooched my blinker undoing what I've done :cry:
*sigh* oh well, I'll call the dealerships and see who has one I can grab.
-
Chris, chris, chris... I told you where you could get the led flasher. Now look what u done. Naughty boy.

Is this flasher a 5 pin????
I've had a partsman looking for a frequency doubling disabled flasher for 3 months and according to the aftermarket manufacturers they don't make one nor are they planning to make one

this is the wiring for ur relay based on the data sheet u posted

If u want to pick up a flasher and give it to me along with the relay i'll do it for u

I had that exact wireup, and the signals would flash at a normal rate but the on dash indicator would be lit when the lights were on.
Perhaps my blinker was farked before, I had the simple "jumper" mod done, till I read that it could start a fire, so I pulled it out. And started looking for a micro-relay.
I'm at a loss now. I'll try to re-solder and see if my blinker truly is hooped.
Otherwise, I'm off for the weeekend.
Thanks for your help Steve!

Gimmie a call when u get back and we'll hook up and u can try my
modded flasher and see if thats works before u buy a new one I'll pm u my #

Yes, but no more than a bulb does.
But why add the heat and load if you don't have to :D
Plus if Chris did that I wouldn't get to make really long posts and get my post count up :lol: :wink:

So, Rookie's wiring works. In fact it works just like I had it.
The dash arrows still stay lit, except when flashing normally during blinker duty.
The culprit, two-wire led's on the front. Thats why, stock harness is three-wire. So there is more "voltage sense" stuff going on than what the relay bypasses. Anytime you see me and want to know wtf I am talking about, just ask, me show.
Cheers
Chris
PS Thanks to Rookie for stopping by and talking about an hour or so to figure this all out.

Try wiring your front LED's into the stock side marker harness, it should be a two wire harness instead of three wire.

This is true, the side marker is a two wire harness. Though, I'm saving the side marker for something special!
I could "make" my own three wire front led, and that would entail buying a bunch of yellow led's and making my own circuit board, thus fooling the wiring gods into thinking there is a two filament bulb attached. But that would entail quite a bit of work+time+money. Of which, I'm short on all three.

Wire your front turn signals and your "special" side markers to the same existing side marker harness. The only downside I see is the front a side signals will flash together instead of alternating.

Seen the new "Jeep Style" surface mount rear leds?
http://led-r-us.com/sttlights.shtml
Purty, pricey, stock looking goodness. Now with the ability to not melt kicked up snow in the winter!
