Yeah. That would be the smartest, but of course that could be insuffient charging time. My alternator works as you describe, with one difference. When the car crosses 40mph, the alt begins to run all the time. Inly my alternator switch prevents that. And sometimes, after I key on and in some ither situations it runs at fjll on acceleration. The switch prevents that.
