Ok, my tach died. I just quit while doing a lap. I had to rely on "feel" to finish the race.
I looked at the cable at both ends...conected well. Now, before I start ripping things apart, what should I be looking for? I have never taken one apart before. I was thinking the drive at the engine could be the cause. Will there be be little bits of torn metal in there? How do I check if the unit itselt is faulty?
