I have a ho alternator currently installed, it's a 240a. When I first start the vehicle in the morning it will charge around 14.2 to 14.6v then slowing drop to 13.6 while driving. I know that when the batteries reach full charge the alternator is supposed to kick down like it's doing to prevent overcharging. My question is will it jump back up to 14.4 when I start hammering on the system and draining the batteries? I ask this because most amps are rated at 14.4v.
