Most of us own a multimeter and know the basics of how to use it. This article talks about how to test specific components in the automobiles electrical system. Some of the tests require additional equipment which might make it impractical for the average guy to preform but it's still good to have a working knowledge of how they can be done. I think that most everyone will walk away with a little better understanding of who valuable this tool can be when the lights go out or the darn thing wont start.
