If you aree connecting the grey wire to the "S" terminal which is signal and the purple wire to "I" for ignition and black to the "G" for ground, and it doesnt start? Sounds like you have a bad tach. Might be shorted out internally if its hooked up right.

You can try and hook it up to another engine or send it back to manufactuer and let them test it. If you know anyone with a good tach you could always try theres.
