That tap did the trick just fine. What a relief!! Now I can go in and try to fix it when my fingers defrost. At lease now I do not have to worry every time I drive it. Tapping brings it down to normal.
BTW , it creeps up with vibration, when I hit a small pot hole or road seam it would go up. This explains why my mechanic said “I had it running for an hour and the needle never moved”

After cleaning the nuts, shouldn’t I run that ground while I am back there? It will sure beat removing and installing the cluster twice. I will just have to live with the “was it the nuts or the ground” question for the rest of my life (I hope).

Big Thanks, my wife like the car more the less I spent on it.
