If your car won’t start one of the first things you should check is the alternator. The alternator is responsible for charging the battery and keeping the electrical system of the car running. There are a few ways to test the alternator to see if it is the cause of the problem.
First you can check the output of the alternator with a voltmeter. The voltmeter should read around 14 volts when the engine is running. If it reads lower than that the alternator may be the problem.
Another way to test the alternator is to start the car and then disconnect the battery. If the car dies it’s a good sign that the alternator is not working properly.
If you suspect that the alternator is the problem take it to a mechanic to have it checked. They will be able to test it with a more sophisticated tool and determine if it needs to be replaced.
