check engine light ....doesn't come on

Help ????

I have a 94 sentra GA16. When I turn the key on and all the idiot lights come on......my check engine light does NOT come on. I checked the light bub and it is good. I checked the socket in the instrument cluster and there is NO voltage. Does anyone know what could cause this. Is it a bad trace on the circuit board??? Maybe a broken wire???

It would not be a real problem as the car runs great, .... but I can't smog it unless this light works when its suppposed to....

Thanks for any help
