Can a car run with a bad alternator?
The short answer is yes a car can be driven short distances with a faulty alternator. If an alternator is giving a low charge it will but a load on the engine trying to ineffectually charge a battery and the battery will slowly die as the alternator gets weaker and weaker and cannot sufficiently recharge the batter.

At its basic level an alternator does not need a battery to operate. If a car is running and the battery somehow fails or the battery was discharged and the car was jump started from another car the alternator will function. Without a battery the voltage regulator will not detect or measure any voltage.

How do you check an alternator with a screwdriver?
Test the alternator for magnetism. Use a metal screwdriver and place the metal end very near the bolt on the alternator pulley. It’s on the front of the alternator and the alternator belt goes round the pulley. The end of the screwdriver is not drawn towards the bolt as there isn’t any electrical magnetism.
What happens if you disconnect the positive terminal first?

Is it OK to not drive your car for a month?

Here are more reasons not to let your car sit for several weeks or longer: Tires slowly lose air under all conditions but especially during cold weather.
Does revving the engine charge the battery?
And when an alternator turns faster, it produces more electricity. That way, all of the alternator’s power can be directed to recharging the battery. Once the car starts, you CAN rev it up to charge the battery faster, but the best way to do that is to just drive it.
