Checked fuses yesterday. The instrument lamp fuse was fine.
I am thinking I may have screwed something up previously when I was fixing my oil pressure gauge. Is there something that I could have left disconnected that would cause the problem?
All guage lights are not working. Both center console and speedo/tach lights are not working

Hi b,
There's a spade ground connection on the back of the tachometer and speedometer.
Have you checked those?
Not sure how they may have been disconnected though while working on the center gauge cluster. Has the dash been apart recently?
Is the top of the center gauge bezel cracked/broken? Sometimes that causes a ground problem.
Regards,
Alan

You can quickly verify if you have ground issue.
With the lights on:
Simply connect a long wire from any ground point (directly to the battery is easiest in our cars) and touch the other end to any metal part of the center console.

I'll need to shuffle cars around to check voltage at the fuse, so I will save that for another day

Thanks for the suggestion. I checked ground between the battery and the guage cluster with an ohmmeter. All ok. Plus I tried your approach to see if the lights would come on. No luck.

The wire coil in the potentiometer will break leaving the only functioning setting at the full bright point. Pull the headlight switch out and rotate it to the point that the courtesy lights come on. If your dash lights come on then your POT coil is broken.
