    Bike runs OK with no other issues?

    Pull the rear cover on the Atari assembly and make sure you have 12V power to the tach - Br to B. Also check the continuity from the grey wire on the tach to the TCI 4 pin connector grey wire.

    If you have the 12V power and continuity (less than 1 ohm) on the grey wire odds are the tach is bad and will need to be replaced. You can check this thread on some further testing that might be done on the tach itself before purchasing a replacement.
