glow plug relay led indicator

trying to get glowplug to work in instrument cluster

  hopefully someone can help with this.


 I am restoring a MK1 GL, where the previous owner had installed a 1.6td. I have wired up the glowplug relay and it works or at least it starts easily, but the glow plug indicator light will not come on. I have tried 2 different relays. I have only connected the output to a normal bulb for now, but no light.

 Also, I want to get it to work in the dash and have changed the led cluster to he one with the 5 led's,  the centre one being  for the glowplug light.
 I need to put a wire from the relay to Pin 10  on the white connector plug to dash to work the glowplug light. For this  I need to open the connector and put in the  wire  and  the metal contact part which makes the contact on the  dash circuit board.  Any ideas where I would get these bits. or maybe someone has a spare connector they are willing to sell.

Thanks for any help or advice.

There are little tabs on the connector edges, if you release the tabs, then you can lift the Keeper.
Once the keeper is lifted then your wires are free to come out the back… and they will all come out of you let them.  So Snap a pic. prior.  Once the Keeper is out of the way you can move your pins about.

The Glow plug LED may be burned out.
It is easy to check.  Take a 9vdc battery and put on end on the input side of the led on the back side of the cluster (little row of pins), and the other on the Brown (earth)on the pair of pins opposite.  If the lamp is good it will light. You may have to reverse the leads to the LED as I can't remember which is positive and which is negative.  If you have a DVOM with a diode tester, you can use it to power the led.

Here is the back side of a Cabby cluster,  in the middle between the Speedo and the TACH are the Little rows of Pinch pins.  There are upper and lower, those are the takeoffs for the turns warning lamps and in your case the Glowplug.

You can take the shroud off the cluster.
Carefully take the mylar off, and place one piece of electrical tape over the pin side of the plastic tongue.
replace the mylar, then the shroud you have just tightened up your connector.



As for the Pin, once I new that the led/lamp lit by using the 9vdc test.  I would cut the wire on the  back side of the connector and splice it there.

I have a connector and wires and have the diesel Haynes manual for mk1 golf somewhere if its any use

 Thanks Guys for you responses,

  Briano,  The problem is that the connector which is a 14 pin only uses 10 or 11 of the slots, the others are empty, so there is no wire to splice into.
This was a petrol loom so there was no glowplug wire and that  is what Im trying to do.
Sportrucker has offered a connector and  wires which would allow me to open my connector and put in the missing wires and pins. Once I do this I can check the Led. I have taken the glowplug  LED and mylar printed circuit from another diesel  cluster. I'm trying to make an authentic diesel cluster with glowplug and rev counter, with little success so far.

 Any idea why the relay will not light my test bulb.

  Sportrucker,  Thanks for you offer.  I will send you a PM.

The issue with the rev counter is that you need an alternator with a W jack.
or along with that you can go to 4crawler as he has a Tach kit for VW diesels.

VW Diesel Tachometer

The LED can be tested on the mylar itself.
Those Pins used to be avail here at Radio Shack.  They were popular on computers back in the day (you might call them Tandy.

You can probably find similar on the Euro Ebay, those are the correct pins. You could probably email that Gent for the correct pins….

if you want a working rev counter you need a diesel cluster, the petrol one wont work even if you run the wire to the W terminal on the alternator

  Rubjonny, yeah I have been messing around with this for a while.

 The green pcb circuit on my original dash cluster was damaged, so i got another dash cluster and swapped over the green circuit to my own dash.
The replacment dash was a diesel dash with the clock which I did not want, the only other part i used was to take the glowplug led and use it in my own dash.

I am looking for a mk1 diesel tach which are as scarce as hens teeth, so in the meantime  saw where you could make the petrol tach work by modifing the board as detailed on the VW Diesel site, but this did not work for me.

Then I got another petrol tach but the needle got broke in transit, so I took the modified board out of my own tach and replaced it with an original board  from the tach which I bought.
So after all this, I'm back to square 1.   I have a petrol tach in a diesel car with a W terminal.

  I was wondering if a mk 2 diesel tach will fit into the MK1  cluster. I know the mk2 cluster has 2 connectors, but don't have one to check out.

My other option is to get a Dakota Digital unit which adjusts the signal from W termnal to work with petrol tach. However I would rather try the MK2  diesel tach if I knew that would work.

thanks to everyone for any advice or suggestions.

I think the guide you found is for the TDI right? if so what you have done is modified it to accept a low amp ecu signal, which is different again :lol: perfect for mk3 and mk4 ecu, but no good for a W signal :(

MK2 clocks will go with a bit of splicing and modifying of the side brackets, popular mod back in the day. they are very similar in size its just side brackets are in a different spot and the plugs on the bottom differ is all

just note there are 2 types of mk2 clocks pre-90 and 90spec, the pre-90- ones have 2 plugs on and theres a handy diagram thats been out for donkeys. the 90sopec just has the 1 plug, its same amount of effort to fit just need to do a little more investigation on the wiring side. pretty much same wiring colours, main thing is the mfa equipped ones have an extra earth and for the level sender this needs wired direct to the clocks not via the 42/43 relay like the pre-90 cluster

 No, This is the modification I made, as detailed here . ( http://vwdiesel.net/forum/index.php/topic,3741.0.html.).

  And no i dont want to change the cluster to a MK 2 as I know it will not fit.  What i was wondering is if the actual tach from a mk2 could be swapped over to the mk1 clocks. Probably not.

if the mk2 tach controller is similar in size to the ones in your link then you could probably squeeze it in easy enough, depending on the age/type it might even swap right in
