h4 harness issues
 
put the harness in a few months ago, worked great, huge improvement

but now, only my low beams work, when i turn my high beams on, i have no lights at all (parking lights work of course)

i checked all connections (battery, ground at both lights, and plug going into the light)

everything was good

Now the weird part is the brights do work once in a while?

I was told it could be those relays? is this true? where can i find some new relays that will last more than a few months?

thanks in advance

Does it have relays like the putco harness?

cruiser54 05-28-2013 07:17 AM

If Putco, BW4136 relays.

black2000xj 05-28-2013 07:24 AM

yes its the putco, has some chinese marking on the relays now, napa or carquest couldnt cross reference b/c of the chinese

does napa carry what i need, if i take those numbers to them?

thanks guys, I appreciate it...hopefully those last longer than the chinese ones that came with it

I've found them available at Advance Auto. AA lists two.

Part # r4136 as "BWD Relay"
Part # r4136p as "BWD Headlight Relay"

I went w/#r4136p. These relays won't mount to the PUTCO bracket. My one original PUTCO relay is still doing fine.

napa dont carry putco anymore

will the r4136 fit my harness?

PocketsEmpty 05-28-2013 08:32 AM

So, did you replace any of the relays? do you have factory fogs?

black2000xj 05-28-2013 08:39 AM

im trying to find a replacement relay, but nobody sells just the relays, i have to buy the whole harness again

the numbers i was given dont match up according to napa or carquest

customer service says to contact the place where i bought them and it will be under warranty. Well thats great but i forgot where i ordered them from

and no on the factory fog lights...jeep never had them...

EZEARL 05-28-2013 08:40 AM

black2000xj,
Yea,it'll fit. My harness is a PUTCO also. I went with r4136p because the housing was of heavier material. Just type in r4136 and/or r4136p. Both will come up.

http://shop.advanceautoparts.com/web...hedFrom=header

I got the link, i see what i need, its just the one guy said they wont fit the harness...i just want to remove the old, plug in the new and be done

Does this issue sound like a relay, with the high beams only not working


*thanks for the link...i will get some tonight

EZEARL 05-28-2013 09:00 AM

I changed out my relays on the AA parking lot. It fits.

My problem started with my high beams not working all the time. Then one night nothing. Next day I switched the two PUTCO relays and hi's worked. I could get the bad relay to work by pinching the housing but of course that would never do. Relay was sticking open.

If you look at the pics at AA's site you'll see that the housing is diff from the PUTCO so you can't mount them on the PUTCO bracket. I made one to work but you could just zip tie it somewhere.

oh i just zipped tied them together and tucked them in the wheel well

great i will get some tonight...hopefully this will fix it

EZEARL 05-28-2013 09:27 AM

Put your lo beam relay on the hi beam harness to check. Both relays are the same.

Wonder if anyone else besides us has had a problem with the hi beam relay? My lo beam one is fine. HOPE I didn't just jinx myself!

i didnt know ther was a difference...i will try switching them tonight when i get home to see

black2000xj 05-30-2013 06:16 AM

ok guys bought 2 new relays from AA

i installed them and i still have no brights. I took both off, switched them around and got the same results

cleaned all the grounds, but i still cant get my brights to work. Do you think its the harness or the headlight itself?

As mentioned before, the high beams will work once in a while, id say about 10% of the time

any ideas? anything i should do..all the connections are made with die electric grease so i know water and dirt shouldnt be a issue :dunno::dunno::dunno:

Help!

Check for current going into relay with test light .

I got to have current going thru, my low beams work. But its my high beams, didnt work with the old relays, still dont work with the new relays

I dont think it can be a ground issue b/c if the grounds were bad i wouldnt have any headlights....right??

Both relays have own grounds from putco harness each relay gets separate power from factory xj plug. check for power going into high beam relay from factory plug .

ok i will...I might just have my buddy who does led wiring make me another harness, with cheaper bosch relays instead of these chinese one

but i will take a look tonight

Its not the harness its a bad connection . You said they work every once in a while ill bet it at the factory plug.

Why guess when you can test?

EZEARL 05-30-2013 07:32 AM

Not only check for power but make sure all the wire contacts that deal with the hi's are inserted all the way and lock into the connectors. Had such a situation with a brand new vehicle's ignition system yrs back. Tested positive for power but the contact would push back into the connector when plugged in causing an intermittent loss of power.

Good morning back at ya!! Off to work I go. Know how hard it is to sell propane in Arizona on 85* days?

Propane and propane accessories? Does your name happen to be Hank Hill? :lol:

Back on topic...I've been using dielectric grease on every darned electrical connector I mess with. Did you do that? :p I plan on getting my new harness installed here as soon as I wrap up my disc conversion..

salad 05-30-2013 02:00 PM

Beware: if your original connectors are weak and don't "pinch" very well on the female side, dielectric grease is causing you problems. Dielectric grease is an INSULATOR - it is like caulking that never dries. It needs to be applied around the edges like a sealant. Think about it - do you do the edge of your water pump with RTV, or fill the whole unit and then wonder why you're overheating? Why would you do that with an electrical connector?

While you're checking your connectors, do the following
- Take them all apart
- Genty clean them with a brass wire brush and a heptane or hexane contact cleaner. You may have to alternate to remove all corrosion and contaminants
- Use a dental pick on female connectors to end the prongs inward. The idea is to get them to grip onto the male pins better
- Apply a light amount of a conductive electrical grease on either the pin or socket. Examples of these are Gardner Bender OX-GARD and Ideal NOALOX. You can find these at Home Depot, Lowes, etc. (Other products here: http://www.k1ttt.net/technote/antiox.html)
- Apply dielectric grease around the perimeter of the connector. Do not get any on the actual conductor. Remember, its like a gasket.
- Reassemble, wrap with tape if you feel like it.

A multimeter is essential for this type of work. Runs and connectors should read 0.3 ohms or less. When I installed my Putco harness I did the above, my grounds are 0.1 ohm to the battery and well protected from the elements.

Good info. Apparently everything my dad taught me about the stuff was a lie :lol: I guess I've been lucky so far

It's a common misconception. The stuff will keep out water when applied to connections, but it's solely dependent on the socket-side being strong enough to displace enough of the grease in order to make contact.

JerrytheJeep 05-30-2013 09:26 PM

I used it yesterday on a 97 rear turn signal, didn't work at first cuz the bulb burnt up. New one didn't work either, but after a small dab of dielectric grease to the connections it worked just fine? I also used the stuff in every one of my connections I could find following cruiser54's instructions, and I haven't seen any issues. Should we really worry about it?
