I have a 2001 chevy Monte Carlo, I had the alternator checked on it and it came back good. But the lights are still on and my battery is not being charged. What could this be?

Could be the computer controlled of the alternator's field generation circuit-double check wiring

The lights are on because of the low state of charge of the battery.
Ther eis a fusible link that runs off the starter solenoid to the alternator. That may be burnt up not allowing your alternator to charge. Ther eis also a 10 am p fuse that could be blown in your underhood junction block.

Have you had check engine light? If so please respond the any codes that have been recorded.
If you don't have a scanner, go to your local AP store and get a free scan. Like the other stated most likely a speed senor.
Check in see if there is any DTC codes, also have the ignition switch checked if no codes are found.
Like the others have stated there is a fuseable link and fuses involved with this circuit as well.
