ALTERNATORS

How do you know is the car alternator is bad?

By Li Chenyu / hcfire360 November

You can remove it and have a mechanic test if its bad, many auto parts stores will test it for free or for a small fee. If the alternator is completely busted the car will start and quickly sputter and quit very quickly because the battery can't run the car very long before it's completely drained. If you get a jump start the car runs great and once the cables are removed the car quits after a few minutes or less. Best way to be sure, have a mechanic look at it.
