Is your battery good? And just because you changed the alt. doesn't mena the new one is good. It has happened before. If you have a volt meter then test it yourself, if you don't then it is like $10-20 at sears for a digital one, and will save you some headache.

if your alt is good and batt is good you could have a internal pcm problem. check for codes?
