• Alternator testing without a multimeter can be tricky, but it is possible with the right tools and knowledge. The first step is to identify the three main parts of the alternator: the stator, the rotor, and the rectifier. The stator is the stationary part of the alternator that contains the windings. The rotor is the rotating part of the alternator that contains the magnets. The rectifier is a bridge device that converts alternating current (AC) into direct current (DC). - Source: Internet
• Using equipment to test your battery will be even more precise. Use a multimeter or a battery load tester for the job. If you don’t have either of those, places like Autozone or Advanced Auto Parts will test your battery for free at their stores. - Source: Internet

• To know whether the car battery is already at the end of its life, regular testing must be carried out at least twice a year. A multimeter is an excellent diagnostic tool that helps measure the voltage of the car battery. This tool is a must in every car owner’s toolbox. It can test both the alternator and battery for problems making car diagnostics a lot easier. - Source: Internet
• When you go to test the alternator with the multimeter, you will do it the same way as you did the battery test. Be sure to keep your engine running this time as you do the test. Your alternator will be good if you get a reading of at least 13.8 volts, but preferably up to 14.4 volts. - Source: Internet
• If the tested battery is good, the multimeter will read exactly or slightly lower than the battery’s voltage. For example, if your AA battery is 1.5V, the multimeter should read around 1.5 or 1.49V. - Source: Internet
• If the battery is not working properly, then it might be time to check the Alternator. The alternator charges the battery. First of all, turn on all the headlights, and other electrical appliances in the car. If the multimeter reading is less than 13.15, then the alternator is faulty and ought to be replaced. - Source: Internet
• Car Battery Testing & Voltage: It’s important to test your battery and electrical system regularly, not just when it’s starting to show signs of weakness. Proactively testing it (or making sure your mechanic does) twice a year will help reduce your chances of failure. Most retailers offer a simple free five-minute battery test. Use our Find a Retailer for a location near you to get a free battery test. - Source: Internet
• If the multimeter reads less than 12.6 volts, disconnect the battery and fully charge it using a battery charger. Then let it rest overnight. If it holds a charge when it’s not connected to the car – something is draining the battery far faster than the computer memory and digital clock. - Source: Internet
• Set your multimeter to DC voltage above the battery’s voltage. Connect the red probe to the positive terminal and the black probe to the negative terminal of your battery. Your multimeter should read the ideal battery voltage range if your battery is fine. Also, measure your battery’s amperage (A⎓) and compare it with the ideal value. - Source: Internet
• So with the engine running (and being mindful about moving parts) conduct the same battery test as above with your multimeter. A healthy charging system should give a reading of between 13.8V and 14.4V at regular idle speed. - Source: Internet
• Another way to test the alternator is to start the car and then turn on all of the lights. If the lights dim, then that means the alternator is not charging the battery properly. If you notice either of these symptoms, then it is best to take your car to a mechanic to get it checked out. - Source: Internet
