It’s awesome that you want to become more familiar with your car! A good alternator puts out about 13.5 to 15 volts of electricity. If you’re checking the voltage of your car’s alternator, it should be at a minimum of 13.
Many people don’t realize just how important a car’s alternator is, as it provides most of the electricity to your car. It provides the electrical power to charge the
car’s battery
, and other electrical components, like the
headlights
, power windows, dashboard instruments, heated seats, and more.
If your alternator isn’t working property, your car may not start. If you suspect that something is wrong with your car’s alternator, it’s best to take it to a trained professional.
