there is a lengthy way to test your alternator to find out if the regulator is bad or if the circuit wire from alternator to ignition is bad.

Buy a haynes automotive repair book.Look in section 5-17 and 18.It will explain a quick way for you to test where your problem is.
I would tell you but its too much steps to test plus the book has pictures.
