I don't think you want to wire the alternator (charge light) to ground!
The alternator charging lamp has ignition feed on one side like all the other lamps.

The charging lamp is on with the key on engine off, because there is ground from the alternator.
Engine running, the volts is the same on either side of the lamp, and the lamp is out.
