Ok fitted the venom led rear lights today, willget some pics up later, indicators and break lights work fine, however the rear lights don't? no voltage at the back?? tried to trace the cableing backbut can seeanything obvious.....

 

so thoght i'd check the fuses, found one blown ( top row 3rd from front of car, what does this one do????), which didnt solve it :headvswal

 

However with this fuse replaced, this is where i need the help, there is a cable in the light pod that started to smoke, and has now melted the insulation!!! with the fuse remove all is fine, but no rear lights, also with the lights on the head lights only use the mian bulb,even when the switch is only on side lights and i cant "flash"with the lights on, it only work when the lights are off???

 

Can anybody tell me what this fuse powers and WTF is going on, looks like i'm gonna have to replace the dash loom now :headvswal :headvswal

 

And still no rear lights!!! going on holiday thursday and need to move the car about 1/4 mile to a secure garage. so really wanted to get it all done today,

 

Anybody got any ideas on this and has any body got a lighting loom?? will post in the wanted section for this as well.

 

 

sorry for the long post

Cheers

Check the block connectors behind the fusebox, sometimes they get loose.

Sounds Stupid I know, but have you tried changeing the wiring round on the tail lights as LED's only work if current is flowing in the corret dirrection. + I earthed all mine to the body of the car rather than to the earth on existing loom.

could that sovle all three probs??? rear lights, smoking wires and screwed up head lights?

 

Cheers

Followed the write up and diagrames that luke sent me, so it should be right,however i will check. surley this wouldn't cause the other probs though.

 

Neil

Melted wires indicate that you have a "live wire shorting out "

 

FIRST QUESTION.... Was everything OK BEFORE you started this job???

If answer is YES then YOU have caused the fault.. Go back and check where you have gone wrong or where you have lefy a bare wire touching the chassis.

Had same prob with mine rear lights wouldnt work had to tchange wires around then they worked fine. I chose outer ring for running lights but they where too bright so had to put 100ohm resisters in line to dim them down (thanks to advice of a fellow member) As for the other lights problem i guess you didnt have this prob b4 you put the venums in? You could have a bad earth somewhere or a bare live wire touching another connector cant understand why putting the venoms in would interfere with the front lights? Only way you would blow a fuse is if you connected a live with a live or touched a live against i live. Your welcome to look at how mine are wired up

Nope just checked and it def the right way round,changedon side overand it made no difference.

I bought the car in peices so have never had the light working, i have a resistor as well,the way it's wire up is out rings for side lights andthen they go brighter when braking. and all 4 inners are indicators.

 

just had a though, can you put a resistor in the wrong way round? if so can see why the brake lights would work and not the side lights?

 

Neil

just remebered there's no voltage at the back for the side lights,

 

And the funny thing is the fuse doesnt blow,i haveto take it out to stop the insulation melting

 

Neil

how have you wired the new lights up? have you wired each individuel light up in a link eg All the brown wires together first then having one wire coming from the link to the respective wire on the loom?

 

The rest of the wires ie black wire the same, and also the brake lights, red wire?

 

Thats how i done mine

Left hand side....

 

both browns together and both black for outer ring together,

 

both reds together and both blacks for iner ring together, same for the right hand side, only differenceis ai have the resistor on the right connectedin with the side light cct to the outer ring.. so side light cctwith resistor and break lights together in the outer ring on the right hand side, can see how this would make the left hand side work the same but followed the diagrame luke sent me.

 

left side connected to left nissan loom and right side connected to right nissan loom

 

Neil

hmm seems complicated way its been wired up, thats prob your problem im guessing you have the brake circuit and lighting circuit wrong somewhere i think your making life difficult for yourself just use outer rings for brake or running lights inner rings for one or the other too that way its easier to follow each circuit

 

dont think you can put a resister in the wrong way round

 

im wondering if youve connected the live brake to the live rear light?

as i've said i followed the wireing diagramme to the T, gotta go to work now, i start at 3, but will check back later.

 

Neil

change the black wire and brown wire around if you have brown as live and black as earth change it so black is live and brown is earth thats what i had to do as i automatcally assumed black was earth

You cannot wire up the 2 rear brake light ciruits as one or you'll have no brake lights They are 2 independent systems. You can run 2 or all 3 rings as brakes from one ciruit. Or 1 from one and 2 from the other.

This is a safety design feature to ensure that if one circuit fails you will still have a brake light on each side.

 

I think you'll find this is you tail light problem.

 

Didn't know you could have outer as Brake and tail. How do you do that. Got any info

I cant see how that can be done either as in a duel stop/tail light bulb there is 2 fillaments but then im no electrition

Plug your old light clusters back in and check they work ok first.

No left hand side lights and break lights are on left hand side loom and right hand side is on the righth and loom. will psot up pic of the wiring diagrame luke sent me.

Have no idea the car had norear lights before i put these in, and has no rear light's if i take them out so nothing to check with, havent been any where nearthe light pod, so cant see how i could have cause this. :nono:

right from the loom the wires are as follows......

 

black = earth

green/black line = indicator

yellow/red line = tail light

red = brake

these are the colours of the wires going into the stock loom connector coming out of the connector to the stock lighting they should be.....

 

black earth into connector-black earth out to lights

green/ black line into connector- green/yellow line out to indicator

yellow/red line into connector- green/red line out to rear lights

red going into connector-red/green line out to brake lights

 

hope that makes sense and helps you locate correct wires

well got it all working, and the way luke said to wire it up, which is good, now 4 outer rings are dimmed as rear lights and then go brighter when the break pedel is pushed, and 4 inners as indicators :dance:

 

however, it would seam that whatever was causing the melting wire hadn't finished being destructive..... the whole cable from pod to fuse box is melted and started to melt other cables, quiet lucky the car didnt go up!! still not sire what has caused it so gonna replace the fuse box and the whole interior loom just to be on the safe side. hopefully this will solve any probs, however if anyone can shed some light on this it would bea great help as dont wanna replace the loom just for that one to burn out.

 

Neil

The fuse you replaced is for "Clearance Lights".

 

Is yours an import?

Has somebody changed the lights/bumper and fecked up the wiring?

yes it's an import, not sure about the bumper as the car is in bits, it's got a standard rear bumper, and no front bumper, doesn't seam to have been messed about with.

 

think i'll just have rip everything out and replace the dash wiring loom.

 

Neil

I cant see how that can be done either as in a duel stop/tail light bulb there is 2 fillaments but then im no electrition

 

 

The way it's wired up it all works fine :dance:

 

just need to replacethe dash loom now :cry:

 

after talking to Luke and checking the car over it seams that who ever had this before had royally F**ked up the wiring so onlything todo is replace the loom behind the dash, not looking forward to doing that, need to get hold of one first. :cry: :cry:

after checking the wiring in sode the car the Answer is YES... coonts

 

wish ppl would leave stuff alone if they dont know what there doing. :nono: :rant: :rant:
