Top 5 Signs of Alternator Problems
It all starts with a few telltale problems It all starts with a few telltale problems: A dash light coming on for a brief moment, maybe dimmed headlights and a few flickering gauges. Perhaps there’s even an odd smell, or a growling sound coming from under the hood. Is this a case of automotive possession? No. Most likely it’s one of many possible alternator problems, and without a little attention, this problem can cause car trouble ranging from slow starts all the way up to a dead car. While an alternator is a relatively simple component containing only a few parts, it plays a critical role in any vehicle’s operation. Essentially it turns the mechanical energy of the engine’s rotating crank shaft into electricity through induction. Wires within the alternator cut through a magnetic field; this in turn induces electrical current. That current is used to power your car’s accessories, which can be anything from headlights to the electro-hydraulic lifts on a snow plow. The alternator also keeps the battery fully charged, providing the power it needs to start the car. Because the alternator is connected to (and critical for) other vehicle systems, any mechanical auto problems can have an affect on its function and have an affect on diagnosing car problems. However, paying attention to the five trouble signs on this list can make diagnosing car trouble related to the alternator a little easier. Keep reading to find out what you should be on the lookout for.
В 5: Warning Light
Within the instrument cluster of most cars built in the last decade is a warning light dedicated to signaling an alternator issue. In most cases the light is shaped like a battery, though some show “ALT” or “GEN,” meaning alternator or generator, respectively. Many people see this light and instinctively think they have a battery problem, which is symptom that will be covered later, but that’s not really why the light goes on. This light is linked to computer systems within the car monitoring the voltage output of the alternator. If the alternator’s output goes below or above a pre-set limit then the dash light comes on. Once the output is within range the light remains unlit. In the early stages of alternator problems the light can seem to flicker — on for just a second and then off again. Or maybe it lights up only when accessories are activated. For instance, let’s say its nighttime and the headlights are on and everything is working just fine. Then it begins to rain. As you flick on the windshield wipers the warning light comes on. Turn off the wipers and it goes away. While that may initially seem like an aggravating problem, the warning light is doing its job exactly. Most alternators have an output between 13 and 14.5 volts that they try to maintain at a constant level. As more power is demanded by the headlights, the windshield wipers, your radio, the heated seats, the rear window defroster and so on, the alternator needs to work harder to maintain the necessary voltage. If your car’s alternator is not working to its full potential, or demands are placed on it that it can no longer meet, the voltage will either go above or below the set level and switch on the warning light.
