My Headlights Flicker. What Could That Mean?

It almost never happens with a new car. But, if you are a connoisuer of fine used cars, you may experience flickering headlights, sooner or later. Many times people think this is simply due to a bad wiring connection. Or, the headlight has come loose. However, the most likely culprit is your alternator. Your alternator has things called diodes in them. As the alternator spins, those diodes create a charge that restores your car’s battery. Without the battery being constantly recharged, the battery would die, and the car simply would not go!

Now, once enough of those diodes die so that the alternator is not putting out enough current to make up for the electricity the vehicle is using, the alternator is said to be dead. And, in short order, your battery will be, too!.

Back to the flickering lights. If you are seeing those, there is a very good chance that a diode or two has died in your alternator, and when the alternator spins, no current is created by those dead diodes. Hence, you are experoience an uneven electircal output from the alternator. Logically, as more diodes the, the problem just gets worse.
