well what you are saying is exactly what a vehicle should have. Car batteries are 12 volts and when running the vehicle's charging system will run the vehicle at about 14 volts. So why do you think the alternator is not charging? Unless you are confusing amps with volts??

the guage in the dash will register midway between 11 and 16v at startup-as you drive without any aux systems running; volts begin to drop and power begins to fade. this is the 3rd alt after the orig[1] replacements 1 & 2
