Running an alternator

The load from an alternator occurs when there is a need for it. If you cool the car after a run without charging you are drawing from the battery. Then when you start the car and make a pass the alt is working to replenish what you drew out of the battery while cooling and to keep up with any draw while running. Better to charge while cooling and the load of the alt will be less and consistent.
