Testing an alternator with a multimeter can help identify charging issues in a vehicle. You can set the multimeter to measure DC voltage, then check the battery voltage with the car off—it should read around 12.6 volts. Start the car and test again; a working alternator usually shows 13.8 to 14.4 volts. Are you experiencing specific problems with your vehicle? Sharing more details might help us troubleshoot together!
