Digital Gauge Cluster Repair / Wire Diagram

Hey,

I am looking for someone with a wireing diagram for a s14 digital gauge cluster so I can trouble shoot it.

I am also looking for someone who can repair this for me if they have the skill/ability.

I am willing to pay to get this problem fixed.

Here is what is happening:

Everything works properly except for the HUD and the digital part to the cluster. Now for some reason, when I turn on my lights, my back light to the cluster does not work. If anyone knows where i could replace the entire digital display assembly for a decent price that would be great, or know someone who could trouble shoot/repair this for me.

Thanks,

Ryan

I wish I knew how to do this on a S13 as well

Alright, where are the GURU’s when you need them with a LEGIT question.

Anways, I went ahead and checked all the capasitors with a tester. To my suprise, when i checked them, i put a charge into the capasitors so when I plugged it into my dash it turned on for 3 seconds then died again. THIS IS GREAT NEWs. This means that it works, the problem now lies in the fact:

A: it isnt getting power,

or

B: The ground isn’t sufficient enough.

So my theory is that not enough power to charge the Capasitors, and yes, i replaced some of the capasitors already. So I got into thinking, Diodes, if I am correct, only allow electricity to flow in one direction. My thoughts are one or more of my diodes are toast and not letting enough electricity threw to my capasitors thus letting them charge and send electricity to lgiht my damn speedo up.

How do I correctly test diodes though? Could there be another reason for this? When I get home I will be testing my subharness that came with the cluster to make sure there isnt anything fucked in there.

Is there anyone that could help me out with a wire diagram for the digital displays? or even help me trouble shoot this mess… I am sure it would be benificial to alot of people, as these things commonly break down, but there isnt enough information out on the web to find any solutions.

Thanks for your time!

awesome … I got one or 2 I need to fix

haha, maybee after all the BS i get threw with this, I will be able to repair them myself! or at least offer some guidance. I am going to see an engineer that repairs motherboards for my company at the U of A tomorrow and see what he can help me out with. I will keep you guys posted. But none the less, if anyone wants to add some $0.02 to this that would be great! :rolleyes:

keep updated!!!

i know on most nicer multimeters like flukes there is a diode test setting. If you go the right way it will give resistance i think, or just a thumbs up that its working. If you go the wrong way and its good then theres nothing. If theres nothing both ways its toast!
