Your Saturn contains just about all of the modern automotive conveniences, many of which are electric and, thus, are dependent upon the proper functioning of the Saturn alternator. The Saturn alternator supplies all of the electrical essentials and accessories with the power that they need, by continuously recharging the battery, providing charge all the time that the engine is running. That way, when the vehicle is shut off, the battery has the power to start it again, as it has been re-supplied by the alternator, instead of being left drained by running the various electrical components. Often, your Saturn alternator will start to fail gradually, and you'll be clued into this, if you know what you are looking for, by odd electrical disruptions here and there, such as interior lights that seem too dim, or headlights that are not as bright as usual, turn signals that seem sluggish, windshield wipers that seem to drag along slowly, never quite reaching their usual brisk pace. This signals the time for a voltage test, which will let you know whether you are en route to a failure of your Saturn alternator. You may also want to take the opportunity to check to make sure that all of the wires and belts are secure, as when any of these loosen, there can be a malfunction of your Saturn alternator.
