That test is to be done as follows: With a non magnetic tip screwdriver, or any piece of metal, with the car running, touch the back of the alternator, and there should be magnetism. How this works: The alternator has an electromagnet in it, which is what "creates" the energy needed to charge the battery, therefore when the engine is running, your alternator is one big magnet and any piece of ferromagnetic metal should work (steel) @Corey Davis: Sorry, but with a magnetic screw driver, on any metal part will stick.
