I just noticed today that my tach isn't working.....the speedo works fine, but the tach is at 0. Any ideas?
Follow the cable down from the gauge cluster to the engine block. Chances are it has just come loose on that end. Some folks have just kinda pushed it back in, and others have applied some of that plumber's nylon tape first.
Check the end on the Tach also...mine stopped working after I had cleaned the gunk out by the sprocket and it turned out it come loose at the connection to the tach.
