Replaced bad alternator with new rebuilt one. Battery light on. Good battery. on 2000 Dodge Grand Caravan

Battery light still coming on and alternator is not putting out power. checked connections and all good. It seems like there is a fuse blown but i can't find it. Battery was tested and is fine, just needed charged. Seems that it keeps running just on battery.
