Generator light not coming on with key on but motor not running.

[Rusty Muffler]

I've checked the bulb and connections which is good and I know the generator charges so when should the light come on? 57 Belvedere 301.

The gen light should be on when the car isn't charging enough. It always should be ON when the motor isn't running (with the key on) and can weakly pop on at low idle or in gear and stopped but should go off when idle increases.

So my problem is why is it off? Is there a wire disconnected that tells that light to come on maybe? I'll look into it.

I don't know, be sure to clean all the contacts at both ends and inspect the wires under the dash, check for shorts, maybe change the bulb and make sure the wiring connectors are clean at the voltage reg too.. and make sure no unwated visitors decided to chew on your wires.

Better yet is look at the wiring diagram and see what powers the bulb.
