Need a picture of an 89+ guage cluster + trouble shoot

Guage cluster problems...

I need a picture of a 89+ guage cluster from an N/A fromt he rear. My guage cluster I just picked up is a 90 that was originally NA. converted to turbo and now i put my 87 voltmeter into it. I haad to remove some stuff and IM hoping I put it back together right but im getting no connectivity.

I ran an ohm check between the two screws in the voltmeter and iwas getting resistance.... Anybody have a TSRM link maybe?

Thanks guys

just for reference

Annnnybody... I really need this fixed. I dont want to put the 87 one back together.. Any voltage checks?

heres a link to the wiring diagram for behind the cluster, don't know if it helps since i can't read these things to save my life.

and a link to the part of the tsrm on testing the gauges on it's own:

it doesn't say much about the voltmeter gauge though

hope this helps a little

Good job Ross, you beat me to it................lol

+1.

Still looking for a pic or a common problem

My fuse is fine. I just checked.

 

[Doward]

Yep, I'll show you where i think your problem is, hold on a minute

 

[Doward]

I just went through this on my own gauge cluster

Oh wait... yours is an N/A Gauge? Dunno then... Verify you have 12v between the two screws going into your Voltmeter.

 

[Big Wang Bandit]

Well it was ORIGINALLY an NA cluster. But it was converted to turbo. I removed the turbo box ont he back at Chrises house...

Should i jsut go strip some wire and wrap em around the screws and give it a shot?

Let's reboot.... what gauges are not working. Please list them. You have a handheld multimeter it sounds like. Get the following information with the gauge connected to the car:

1) read voltage across the two terminals of the voltmeter (ign on)
2) do the brake/battery lights come on with the ignition on & engine off

We will proceed from here.

 

[Big Wang Bandit]

None are working... My temp guage was around mid guage when I put everthing back together but once i turned the ignition on it went to the bottom..

I am going from memory. The brake and batter light do not light up. Let me connect everything and get the readings and the correct answer for #2

 

[Big Wang Bandit]

Battery light comes on with key turned to ON position
Brake does not
Voltage across the 2 voltmeter screws is 0.02 volts....

 

[Doward]

Double check you put ALL the hookups in... there's like 3 large ones, and then a little like 4 wire one, with a brown plug. It hooks up in that spot you can see on your pic there.

I believe it's also got a 12volt line in it, for the cluster.

 

[Big Wang Bandit]

They are all on. Ive done this before and made that mistake once.

I do have an odd hookup in the back but Weezel and I figured it was for the super computer being my car is an 87 and DOES have the wiring.

 

[Doward]

That went to the white box for the turbo gauge.

 

[Big Wang Bandit]

Hah. Well that works. But other than that I dont know whats wrong! They all worked before. So I know the harness is fine. It must be because of my voltmeter swappage.

I bet I did somthing to a grounding point on the little green paper wiring on the back.(for a lack of a better term)

If I can get it to work - a voltguage I wouldbe happy as well.

First, if the cluster is not vertical the gauges will read all over the place, so that is probably why your temp was in the middle originally.

You say all gauges are dead. Temp, Oil, Fuel, Volt, and Tach I assume Also the brake light is dead, but the bat light is on.

That all points to a lack of 12V at pin 8 connector C (yellow wire from Gauge fuse).

You need to confirm that you have 12V from the Gauge fuse (solid yellow wire).

 

[3p141592654]

Also, the volt gauge shares a ground (A8 white-black)) with the Tach (and turbo gauge). If you had a bad ground your other gauges would still be working.

 

[Big Wang Bandit]

Sorry 3p but where would I find A8?

I just tossed my old guages back in and they worked. I figure its a dirty contact now... qtip and some fine grit sandpaper?

 

[3p141592654]

have a look here. It shows pictures of the gauge connectors.
