Stock Tach acting up
Hey Guys, Nice warm day in St. Louis, let the car run for the first time in a couple months and I noticed that the tach needle won't go above a certain point regardless of engine RPM. It "looks" like it physically hits something and stops. I took the lens off and gently moved the needle up with my finger and it will go past that point, but then it does the same thing, it just stays within a higher range. I did a lot of things up behind the dash—ventilation, wiring etc., could I have knocked a wire loose or something? I also remember back during the restoration one of the screws in the faceplate had jiggled loose over the years. When I replaced it I got a fingerprint on the faceplate, and when cleaning that I accidentally snagged the needle a couple times with the cloth I was using. It kind of did the same thing, remaining in a position above where it should be. I gently pushed it back down and everything looked OK. I have driven it between then and today and I think I would have noticed if it wasn't working right at that time, but maybe I didn't notice. Anyway, not knowing the internal mechanism, did I break a spring or something internally? Has anyone run into something like this? Most importantly—can it be fixed without removing the whole stinkin' dashboard or everything behind it all over again?
