Load on the generator or alternator.

Load on the alternator, but also check your grounds and battery cable. If your headlights are stock, the drop in RPM shouldn't be noticeable, unless you set your idle below factory specifications.

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.
