My speedometer and tachometer have been giving out. Started about the same time last year. Now the speedometer has totally quit, which I'm assuming I will just change the cable to fix. But the tach im not so sure what to do. It runs fine after about 10 or 15 minutes of driving but nothing when I start out, so a wiring issue doesn't seem to fit? Thoughts?
