Topic: New Dyna Coils... Now tach not working?

[takeitdk]

Recently installed Dyna Coils on my cb400f and now my aftermarket tach isn't reading rpms.  Not even erratic readings... Needle doesn't move.  The light in the tach is on so it's getting juice.

Assuming I didn't botch up the wiring, does anyone know why the tach is now not working? EMF issues? 

Thanks.

what kind of tach?

if it's an electronic aftermarket tach, follow the leads off the tach and see if one of them has come loose during your Dyna coil install. If it's a stock Honda tach, it is mechanical and works off a cable from a Cam drive. The cable must have broke.
