JohnnyWas Posted June 21, 2013 Report Share Posted June 21, 2013 Sooo, I was driving down the expressway today and hit an unavoidable pothole in the right lane (couldn't cut over in time, given the semi to my left!) and upon smashing into this pothole, my tachometer needle dropped below zero, and when I next came to a full stop, it would rest at idle backwards up towards eight again. So basically, the entire range of my needle climb as been twisted counter-clockwise on the face of the tachometer!! What could have made this happened, and where should I look to remedy the issue? Is the tachometer that prone to failure, or did I simply shake something loose somewhere under the hood? THANKS! Quote Link to comment
Ratwagon1600 Posted June 21, 2013 Report Share Posted June 21, 2013 Have you looked on the back of the tacho to see if it has a cylinder selection switch? Some tachos allow you to switch between 4,6 and 8 cylinder engines. Not saying this is the problem, but worth a look. Quote Link to comment
Ranman72 Posted June 22, 2013 Report Share Posted June 22, 2013 factory tach I assume check all your wiring on the back of the tach and check your grounds not sure if they are that prone to breaking Quote Link to comment
JohnnyWas Posted June 22, 2013 Author Report Share Posted June 22, 2013 Ok - well, while driving down the highway today, the needle literally fell off within the gauge, so I guess it's time to replace / upgrade. Quote Link to comment

Sounds like its bin time for the tacho. I'd still be curious if it had the selector switch on the back :) Quote Link to comment
datzenmike Posted June 22, 2013 Report Share Posted June 22, 2013 Take it out and put back on. They just push on like any clock hands. 1 Quote Link to comment
