Hey there friend To check if alternator is false or not there is a simple way of doing it without getting to tear entire car and cables apart. Before you do anything loosen the negative cable but so its still connected to batter.
Start the vehicle, if cant slave it off and start it, while vehicle is runing disconnect the negative wire that you have loosened then if vehicle is runing its good if it dies then your alternator went bad and needs replacment.
If you need to drive badly because cant get a ride to get to schucks or some auto parts store you can bang the heck out of the alternator with a hammer which will charge the coil inside and will loosen some of the dust that collected there. That should be enough for you to get to store and back.
Good luck you can always Private msg me if you have any other Auto Questions.
Good Day.
