i have a 1993 honda civic dx coupe that has an ex gauge cluster in it. just finished rebuilding the motor and re-installing it and now all of a sudden my speedometer stopped working. it doesnt work while im driving and while im just sitting still the speedo goes from 0-120 and back down and just dances all over the place. was wondering if any of you have dealt with this before or what the problem could be. thanx
