ye single wire 'temp' should be a straight earth limiter and max out on full earth

not got anything else tapped into it ? reason i ask is i know they wont run 2 gauges at once
ive made sure the clocks are earthed and the 2 lives are there as well , but if i either try temp gauge pin to earth or fuel gauge to earth nothing happernds , ,, but all the gauges rev/speedo/temp/fuel all slightly move when the cluster is powerd up , i carnt understand why there wont move when earthed

you sure the gauges that dont work dont need a 5v control rather than a direct earth... i know my coolant sensor sees a 5v supply... just not sure if thats before or after the gauge

EDIT: my temp gauge doesnt work either btw... typical, but it moves up slightly when ignition is turned on, like what you say yours does...

just wondering if the sensor that matched the clocks was a 2 pin/signal resisitance one

whats the clocks from the vr6 itself ?

ive tryed a small currant from the wire to earth still nothing , just moves a bit to the start of the gauge , same applys with the fuel gauge , the clocks are from a 1995 2.8 mk3 vr6 golf , i stripped a old set and i can that there is 4 pins to each of the gauges , what they do is another story , as theres too mutch curcity to trace them ,, double checked the earths and lives , as i said early soon as i plug them into a mk3 golf they work fine , so confuseing why 2pin wires can cause these too problems with the cluster :confused:

if you have a golf to test em on can you not multimeter the wire to see what signal is being sent ? or at least earth it to test the theory ?

was my friends car as he was free on the weekend ,so carnt really keep riping his dash out to check wireing ,
its head thashing why 2 single wires dont move when there earthed ,i evern wired the fuel sender unit as that only has one earth one varible 12v live and still nothing i, think i will have to not bother with them and try buying 2 after market gauges and re wire them into the centre consol of the dash ,as i thought with seeing the pin outs on the otherforium , they would work , ,if anyone has a possible daigram or pin out were they the how the hell the wireing is suposed to work from the 2temp and fuel pins ,it would be very greatfull
carnt post pics as yet due to posts

on my test jig I have a resistor going to ground to get the gauges to move, If I remeber right they would not move if I just grounded them. When I am back at work tomorrow I will check what the value of them is and post back with the results.

really ,,, ill be over the moon if this is the problem , as i kjnow i had to use a resitor from my clocks via my standalone ecu to work /ps if all goes well , could u let me know how this would be wired to work

just thinking are you using the right sensors ie the ones from the clock set car not your mk1?
, im useing the vr6 engine sensors from the same car th clocks were from ,:D

if you are using the sensors from the vr6 then they should work without resistors mate, I only used them to replace the sensors in the workshop.

thats that idea in the bin , as ive just drove 10mile back to work shop to try a varibl of resistors from 1k/10k between the pin wire to earth and still nothing ,, what a nightmare:cry:

how short is the pin wire ? through the loom or a direct connection ?

seems strange that the only way it doesnt work is with your wiring as its ok in another car ? did you try it with GTV's little test rig idea ?

frustrating though isnt it :) - it will sort it one way or another

as i tryed it contected with the sensors with no joy , ive then just tryed the 2 pins diect from the clocks with inline resistors then putting them to earth still nothing , only thing i dint try was adding a 12v supply after the resistor , which i didnt wont to risk any damage to the clocks tbh ,,,,and yearh they work fine plugd into the standard mk3 golf vr6 fusebox loom, as i assumed long as the clocks had the main power and earths , the others would be wired up direct to the sensors/ ie 2wires for temp 2 wires for fuel ,2 earths/and the 2 pin sensor pins may have been live , but with not havin no joy somethings just not right , evern thow i feel im close , with everyone help ,,

hi guys yes still stuck regards the 2 gauges on the mk3 vr6 clocks which wont work ive found this wireing daigram but as its a pdf im insure how to load it , heres the link and half way down ull see a english version mk3 golf 1995 when it opens its shows how he gauges are wired but i dont really understand whats what and how its wired can anyone care to look and possible explain

(half way down you will see //((VW Golf 3 1995 Wiring Diagrams (eng.) once opend pull padge down ull see instrument 1 then 2 ?

Sorry for digging an old thread up but just want to double check something.

Is it definetely the red/black or black/green wire that goes into the clocks that provides the tachosignal, as stated at the bottom of the first post?

Cheers,

Craig.
