My tach seems to be a little off. Whenever the truck is not running the tach reads 150 RPM. This got me thinking one day, My tach reading might be 150 to high. Is there any way the bring the tach needle back down to zero? Any info would be appreciated.
You'll have to pull & open the cluster, pull the needle off, and stab it back onto the shaft. Just don't touch the red surfaces of the needle - you can take the color off.
