charging system question

I recently installed a voltmeter in my pickup and noticed that anytime turn on my headlights, wipers, turn signal, etc. etc., my voltage instantly drops from about 14volts to about 10 or 12volts. I have a brand new optima red top battery in it so I doubt it has anything to do with that, so could this mean I need a new alternator?
