You know what happens when the generators in a power system go down: You get a blackout. That's exactly what happens to your car when your Mazda alternator goes on the fritz. Your Mazda alternator supplies electricity to every system in your car. If your Mazda alternator isn't able to keep up with demand, you get dimming lights and eventually a blackout. Sometimes your Mazda alternator will give you notice that things aren't well; if your headlights seem dim or the battery warning light on your dash lights up, that's your Mazda alternator sending a message. Your Mazda alternator is a small generator. It's called the Mazda alternator because it produces alternating current much like what you get inside your home. A device inside your Mazda alternator called the rectifier changes the current to direct current that charges your battery and operates your accessories. Many times on a bad Mazda alternator the Mazda alternator components are fine but the rectifier burns out. Other times, the Mazda alternator bearings or brushes go bad. Either situation requires a new Mazda alternator. A premium new or rebuilt Mazda alternator, like our Mazda 626 alternator, is only a mouse-click away.
