I have a 1993 Toyota Camry I just replace the alternator and got a brand new battery and my battery light still keeps coming on what can I do to fix this problem

clean all connections,make sure ALL are clean,free of corrosion,shines like new,and tight,including grounds.then check the voltage on the battery terminals with a volt meter with the car off.then start the engine and check the battery voltage again.this will be the alternator output voltage.post the two readings here.

Did anyone check the 7.5 alt fuse?
