Question
The RPM needle went hard to the right today gradually and stayed there while driving on the hwy. The needle is now all the way to the right and will not come back or move. Tried turning off car but it did not return. Any ideas? tks

Answer
Hi Kevin... check the circut for the tach,it should be dead when key off, if not trace the circut and see when it is shorting to live. if it has no power start the car. do you now have power..if so, the tach is bad...probably circut board in the dash... hope this helps...merry christmas
