Sideshow, you might be able to clarify this for me. Will the alternator produce a charge if the white wire is disconnected?

I always thought is was a way to shut down the alternator output when you turn the ignition off. Otherwise you could get into a stuation where if there was a wiring fault somewhere that the engine could keep running if the battery was disconnected because the alternator had enough output to excite itself.
