Back in the day of cars without computers, you could have pulled the pos battery teminal to see if the alternator was working correctly. But that isn't the case with today's cars anymore.

The computers in the car require the clean signal that the battery provides for them to work correctly. The alternator simply recharges the battery, and can not safely run the computer control devices in the car.

If you are lucky, you friend another alternator.
If you are unlucky, you friend the computer.

I recommend against ever doing that again in a modern car.
