Default marauder battery light on... Ford guys tech support

Hi guys
Battery light appears on my dash on my 03 marauder 4.6 liter..The factory volt gauge reads 10 volts, my meter reads 10.3 volts running, shut the car off the battery voltage jumps to 11.5 v. So I say alternator, buy one on line New not reman. install it today. The inside voltage gauge reads 14 and so does mine 14.1. Alls good right, wrong, you start the car,no battery light till about 2 mins later,... any ideas, the car cranks over fast and starts all the time, possibly a bad alt out of the box ?????
