somewhere just by attaching a meter to your battery and having you start the car?Can an auto parts store tell whether there is something wrong with your alternator or whether there is a short?
should be able to and i think that they do it for free also
The only real way to test an alternator is to remove it and bring it to the auto parts store. Nearly any of the major auto parts stores will test your alternator for free.
They have a test stand they can install it on. They will spin the alternator to speed and the test stand can run diagnostic tests on the alternator.
They can test it with and without a load to see how it responds.
There is a simpler but less accurate test you can do at home. You will need a digital volt meter.
Set the volt meter to the 24 volt DC range.
Place the positive and negative leads of the volt meter to the matching battery terminals. The meter should read around 12 volts with the ignition in the off position.
Start the engine. The meter should read between 14.5 volts and 16.5 volts. Turn on a couple of accessories like the head lights and the radio. The readings should stay about the same. If the meter reads above or below these readings you have a problem with the alternator.
If the alternator fails this simple at home test the next step is to bring it to the auto parts store for further testing.Can an auto parts store tell whether there is something wrong with your alternator or whether there is a short?
They are not by rule good technicians, but some times they can tell only if the alternator is working to some extension, that's all, I do not see how they can detect a short only using a charging system tester.
no if there is a fault on the alternator will show up as a short curcit anyway so no the test meter will not tell you if its a fault or a shortCan an auto parts store tell whether there is something wrong with your alternator or whether there is a short?
