A lot of new vehicles have a master system fuse under the hood that might be blown.

I've found that the wire from the alternator to the positive terminal (which runs the actual charge to your battery positive terminal) is sometimes bad. You can bypass it by adding a wire at the small post at the back of the alternator then running it to the positive battery cable (attach it any which way). The original wire is the small one which runs attached alongside the battery cable. Bypassing it will let you see if it is bad or not. I actually have left the new wire on this way and never stalled or had starting problems since. Try it even though your battery is fully charged.

New batteries almost always come fully charged. If it was not then charge it with a battery charger and do not use your vehicle alternator to charge a dead battery.
