Default Battery Voltage while running

Went out to start my car this morning and it didn't start. Wouldn't turn over. Well thinking nothing about it I jumped it and drove it to town thinking it would charge. Started fine at the gas station but after sitting for about 2 hrs it refused to start again. The battery is brand new. I'm thinking the alternator is shot. I checked the voltage at the battery with a voltmeter and while running it is only like 12.4-12.7 volts. Seems low to me. Shouldn't it be like 14-15 volts. Oh by the way the car has only sat for about a week prior to starting it for the first time. Any help before I head out to by a new alternator?

make sure that when you replace that Alt that you get a new battery. Right now if you are only getting 12ish volts you are killing your battery.

well i got my new alternator installed. Took about 10 minutes. Gotta love changing these things especially when it'* cold out. Anyways I've yet to drive yet as i'm still charging up the battery. Hopefully all is well in Bonneville land again. My car deserves to be happy again.
