How long can you drive a car without the alternator working?
It entirely depends on the capacity of the car battery. If the battery does not have a full charge, the vehicle may run from 5 to 30 minutes. The runtime will increase in case of a fully charged battery.
Is it bad to drive with a dead 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.
What did I do when my alternator died?
I was driving on the freeway and my car started to make a weird noise. Pulled over to the next lane for the next exit. It automatically died and locked up. I kicked it in neutral and forced it onto the shoulder. Roughly a week or two before that I replaced the alternator and it was running great.
Why is my alternator not starting my car?
If its going over 14.8 volts then your new alternator might be overcharging the battery. If you are positive that the alternator is working fine but still your car is not starting up then there might be issue with the starter motor (which i am sure the mechanic must have noticed)

What causes alternator to die?
An alternator produces power by rotating three plates across a winding of copper wires. These plates can fail one at a time and reduce, but not stop, the power output. As more plates fail, the power drops to levels that will eventually cause the battery to die and the ignition system to fail.
Can a car still run if the alternator is dead?
Technically, yes. You will be able to connect the cables and start the car with the dead alternator, but as soon as you remove the cables the car will stop again. The reason is because the bad alternator doesn’t provide any voltage to keep the car running.
