Like a bad alternator can destroy battery performance, even resulting in total damage. If a car is running with a faulty alternator it may result in many harmful effects on the car. The reading should not change abruptly, if this results in a minor change of readings that’s proof that the alternator is in a good position. Give race to a car engine to increase rpm and observe the change. Now check readings on multimeter that should be somewhat between -0.04 to -0.05. After that turn on all electric accessories like audio systems, lights to put a load on alternator. Connect the multimeter’s black probe with the negative terminal of the battery and black probe to alternator’s body after starting the engine.
#MINITUNE ALTERNATOR TESTER L HOW TO#
In this simple method, we’ll teach you how to test an alternator of the car. This is an old method used by auto electricians to test alternators. Any abnormal noise from the engine side is also a sign to check your car’s alternator. Your vehicle’s weak cranking/starting power may be also an indication for it or dim headlights may refer to the slow performance of alternator. For example, early battery drainage may be a sign of a weak alternator along with battery issues as well. What are the signs of a faulty Alternator?Ī malfunctioning alternator gives many signs before its complete failure. If you checked everything and found them well then it’s time to replace your car’s alternator. It may also be due to the alternator’s voltage regulator problems. There may be numerous reasons for a bad alternator’s voltage, from low rpm to belt or pulley issues. Voltage level should be improved after this, if it’s still giving low volts then check alternator belt and pulley whether they are working well or not. If you’re getting a low reading like 13 or more that may be due to low rpm speed, verify it by increasing engine’s rpm to 1500- 2000. Now check readings on the meter screen, it should be 14 or nearby to make sure that the alternator is doing well. You may also connect the black probe with the negative terminal of battery. If you can easily reach your car alternator then connect the red probe of the multimeter to the alternator positive terminal and the black probe to any metal part near it, it may a bolt or other thing.

There is another process to check the condition of car alternators frequently applied by pro automotive electricians. Same as below 14 voltage will be indication that alternator is not charging battery.If it’s above 14.8 that means alternator is overcharging the battery.If it’s in between 14 to 14.8, it will indicate that alternator is in working condition.Once the car engine has been started, observe current and voltage level of battery.Now tell one of your companion to start the car to check alternator real time performance.For this you’ll need another participant who will start the car, while you’ll observe readings.Testing Realtime Alternator’s Performance. If meter is giving somewhat 12.5 to 13.5 volts that probably means that battery is in good condition, also the alternator.
#MINITUNE ALTERNATOR TESTER L GENERATOR#
Alternator is actually a generator that converts mechanical energy into electrical one.
