Wiring help please! - Indicators and high beams

Hi chaps. so I began to piece, extend and rebuild the front loom of the golf and managed get some reasonable success. A lot of wire stripping, cleaning, soldering and pb tape…..All of the lights work except for the following issues:

Left and right indicators do not work from the stalk (with no clicking noise either) - however the indicators work when the hazard switch is on.

The front lights are single light setup. The small side bulb in the in the headlamp works on the first click of the main light switch on the dash. The second click on the switch doesn't seem to do anything, ie. the main bulb does not light up.

The brights do work on the indicator stalk, which I think operates both filaments of the bulb. The stalk does not stay clicked though (so the brights will only work if the stalk is pulled - is that normal?)

Can anybody help with a diagnosis? I have checked the earths and carried out continuity checks of the wiring. The only strange thing I have seen is the C8 - yel - Right headlight pin 56b wire does not terminate in C8 but rather ends in a female spade connection. The only thing I can think it connects to is a yellow wire running up into the dash is fused with twin 10A fuses and unconnected. Not sure if this was some modification, but I have tried connecting this together and no joy.

My thinking is this twin 10A fused yellow wire is actually a red herring and that the main light switch is knackered. It is the one with the roller combined with the switch on the dash. Is there anyway of testing this switch? Or should I just pick one up and check.

But then should I reconnect 56b to C8?

It is a series 1 if that makes a difference.

Sorry for the long post but any help would be appreciated as I so close to sorting this bad boy out!!!  :D

check you have ign live to the yel/blackwire to pin X on your light switch, then check that the white/black wire on pin 58 is live when the switch is on the 2nd click. check pin 58 on the stalks is live on the 2nd click too, its the other end of the wire from switch pin 58.

the C/18 wire definitely shouldn't have a spade on it that should run direct to the headlight.

if you dont have power to the black/yellow thwen the dip/main wont work, but you know the wiring from the stalk is ok since the flashers do work. both the dip and main beam filaments should light up at the same time when you hold the stalk back to flash

Thanks mate.

Is ign live needed for the indicators to work off the stalk as well?

Sorry if I was unclear, but the wire coming from the main headlamp on the wiring diagram connects to C8, but on my harness, it does not connect to the fuseboard at all and terminates in a female spade at the fuseboard.

Any idea why this might be?

Cheers for the help!

hazard switch have a blue/black ign live feed, to pin 15. this comes from fusebox pin A/13, fuse #19.

sounds like someone had a wiring problem and did a captain bodger on it rather than fixing it properly. you can get the CE1 fusebox pins from Auto Electrical Components, Parts and Accessories for Trade and DIY: Polevolt Ltd, but you'll need a good removal tool as the small ce1 pins in particular are a right sod to remove

Thanks RJ.

Am i correct in saying the hazards and indicators use th same relay and wiring, hence if the hazards work, then its likely a stalk issue if the indicators do not work (I cannot hear the relay clicking either) - is that correct?

Cheers!

exactly right, the wires from the stalk piggy back to the hazard wiring. it is possible for the hazard switch to be broken in such a way that hazards work but indicators dont though so bear that in mind. but you do know that if hazards do work the relay, wiring to the bulbs and fusebox is ok at least. problem is hazard switch, indicator stalk or wiring between them

Legend as always RJ…..it was the ignition live to the fuseboard that I had forgotten to connect…. :banghead:

cheers for the help…

OK, so this all worked when I tested the wiring. I then proceeded to install and route the wiring over the wheel arch and into the engine bay so the wires are all hidden.

Now I have the following issues:

both left and right low beams work on light switch 1st click
only right high beam works on light switch 2nd click
only right brights work on indicator stalk pulled back
left indicator works
right indicator works but low beam flashes as well on right side (both on hazard switch and indicator stalk)

I have checked continuity on all the wires and fuses and loom plugs are well fitted, with clean earths.

I also now have no 12v going to fuel pump, even though on 1st click of the ignition switch i have 12v going to the other 3 pins and a good earth, there is no 12v feed to the pump from the relay.

i am going to change the fuel and hazard relay just a matter of course as they are old.

Seems like a parody of issues there but hopefully it just needs a another look at it and something simple will become apparent…

all sounds like earthing problems to me due to the random spread of issues, but it could be a corroded fusebox causing strange issues. did you remember to connect the chunky earth with the black spade on on the engine loom to the headlight loom white earth jumper block?

Hi!
I have the same problem but im new to working on cars ( bought my first "project" car last week) and english isn't my first language, so i didn't quite catch the fix. If someone could spell it out that would be great :)

First things first.  Check your Fuses, there are 2 Fuses for the hazards/turns.  It is quite common to have working hazards and turns that only glow the indicator in the instruments.  I have removed dash bits and found my turns didn't work after re-assembly.  

The two fuses are low f2-f4  and then f19 for the turns.
So test your fuses first before you assume that there is a major re-wire.

Or is your issue with the headlights?

There are 4 fuses for those, as in 1 each for low beam, and one each for the highs.

Second knowing the year and model you are working on helps us help you quicker.


What do Divorces, Great Coffee, and Car Electrics all have in common?

They all start with GOOD Grounds.

Where are my DIY Links?

Fuses are ok and iv'e changed the relay. I have working headlights, high beams only when keeping the stalk pulled towards me. Indicators not working at all. Hazards are ok. I have a 1980 cabriolet.
