New isn't necessarily new. Did you get a rebuilt alternator, or a reconditioned, or remanufactured? If not new, have it tested and you'll probably find that it's defective. And then, even new might even be bad. Otherwise it could be the voltage regulator or something done during installation, like leaving a connection unplugged.
