I have read earlier posts regarding an adjustment of the volt gauge on earlier cars,
and would like to know if the newer 1990-1995 cars with electronic dash also have this
rheostat style adjustment??

I don't know, but here's the front of the instruments (2 photos), followed by the back with the PCB and white plastic piece lifted off (1 photo). Take a look at the upper left gauge on the back, and you'll see a white plastic tab marked with a "+" and "-". Some kind of adjustment mechanism, perhaps?

thank you Ed, that is very interesting; that could be the adjuster!!???

the bad news for me is that I have buttoned up the dash,
so I will have to deal with this during another project.

still would like to know for certain...Alan....Alan...????

Are you experiencing readings that give you reason to suspect their accuracy or is it more a general interest type of query?

The picture Ed submitted caught my attention as I have never seen the back of the cluster with the outer shroud removed. I have no idea why two tabs would be needed unless one is fixed for a reference point and the other tab pivots?

the gauge shows just a tad bit below the number that reads on my multi meter, and while I had it all apart, I thought I would adjust it, if it were possible.

not a super critical thing, especially now that its all back together; still would like to know if is possible. ?????
