Dead tach GK76

Post by rgvsp »

Would anyone have any insight on to why my tach would be dead as can be? Mine is a total rebuild so it just didn't die suddenly. I've cleaned the connections and swapped an older tach in and it didn't work either. Anyone have an idea of another source of the problem?

I forgot to add that all the fuses are new and everything else on the bike seems to running normally and the bike rides fine.

Hi mate,
supply is the wire from the HT coil (black and something) check for break or its connected to the wrong point at the tacho.

Found the culprit!

If anyone ever has this problem: tach runs off the black/yellow wire coming off of the right (sitting on bike) coil. It goes straight up to the tach. My problem was a loose connection of the black/yellow wire at the pin connector behind the cluster. Just pushed it in and instant tach!
