Thanks for everyone's input. Nothing was wrong with my car with the previous alternator that was 32 years old. I wanted to upgrade it and from the day I installed the new alternator I had the problems. No battery light was ever on before and nothing with my wiring has changed. I haven't done any electrical modifications since the new alternator. The battery light comes on bright when when I first start the car and will stay that way til I rev the car a little. Then the light stays lit but at varying intensities. Sometimes it's barely on and other times it gets brighter (usually at lower rpms). The drain on the battery is very slow. If I charge the battery up it'll last a few days of frequent driving. You can tell the battery isn't charging because it gets harder to start with in time and then has no power at all. Once again the battery is brand new and the battery it replaced was only a year and a half old.
