Your vehicle depends on multiple parts to make it run properly. Those parts make up systems, and the systems work in tandem to keep a vehicle running safely and efficiently. Each component and system play a key role here, and they’re all important in their own way. One of the main parts that keeps your vehicle working the way it should is the alternator. If it’s not in optimal condition and operating correctly, it can cause serious issues. Understanding what the alternator does and the common warning signs that it’s not doing its job can help you keep your car, truck, van, or SUV on the road.
What Does the Alternator Do?
In short, alternators convert mechanical energy from a vehicle’s engine into electrical energy. They power your vehicle’s electrical systems while the engine is running. At the same time, they keep the battery charged so it can provide the electricity needed to start and power your vehicle. All vehicles with internal combustion engines have alternators, but electric vehicles don’t. Some hybrid vehicles have components that are similar to alternators but not quite the same.
Signs Your Alternator May Be Malfunctioning
On the surface, an alternator’s job may sound fairly simple. If it’s malfunctioning, though, you could easily find yourself stranded. With that being the case, be on the lookout for signs that you may need auto repair in Chico, CA to fix or replace a bad alternator.
Dead Battery
One indication that you may have alternator problems is a dead battery. Though several issues can cause a battery to die, including cold weather and inadvertently leaving the headlights on, if your battery dies frequently, the alternator could be the culprit. That’s a sign that the alternator isn’t recharging the battery the way it’s supposed to.
There’s a common test to determine if the alternator may be to blame for a dead battery. It involves giving a vehicle a jump start followed by disconnecting the battery cables. If the vehicle shuts off after disconnecting the battery, the alternator is probably the problem. If the vehicle continues to run after its battery cables have been disconnected, the alternator may not be the issue. Experts warn against trying this test on your own, though, especially if you have a newer vehicle. If it’s not conducted correctly, it could damage some of the vehicle’s electrical components.
Dim or Flickering Lights
Dim or flickering lights are also a warning sign that your alternator isn’t working properly. Both the interior lights and the headlights may not be as bright as usual, or they may flicker when you rev the engine. That means the alternator isn’t generating enough power to maintain consistent electrical output.
Unusual Battery Gauge Readings
Unusual battery gauge readings could also point to a problem with the alternator. The battery gauge tells you how much charge the battery has at any given time. Ideally, you should be aware of where the needle on the gauge rests when your vehicle is running properly. For most vehicles, that’s generally near the middle of the gauge. If the needle drops unusually low or rises higher than normal, that may be a sign that the alternator needs attention.
Keeping Your Alternator Working Properly
Alternators are important components of vehicles with ICEs. The warning signs listed above are common indications that an alternator may not be working properly. If you notice any of these problems, consider taking your vehicle to a mechanic as quickly as possible. Though your vehicle may still be running at the moment, a malfunctioning alternator will eventually leave the battery completely drained and you stranded.
