What Are the Warning Signs of a Bad Alternator?
In terms of car parts, if the battery is the heart of your vehicle’s electrical system, the car part known as the alternator is the brain. It makes sure the battery is charging, the car can start, and the accessories work. If your battery is dying and you're not sure why, it's possible that the alternator in your car may be bad, which happens as the battery overexerts itself trying to maintain power that should be bolstered by the alternator. If you notice any of these warning signs, then it might be time to get a
new alternator
for your car.
Bad Alternator Symptoms
Battery Life Doesn't Last as Long as Usual
If your battery is dying faster than usual, then there might be a problem with the alternator. If you notice that your battery isn't lasting as long as it used to, you should take your car in for a check-up. While dead batteries on their own aren’t necessarily reflective of a greater issue with the electrical system, a continuous drain on these batteries is a fairly surefire sign that the alternator will need to be replaced.
The Car Struggles to Start
If your battery is old and struggling to hold a charge, then it might be time for you to purchase a new battery. However, if the battery is new and the car is still having trouble starting, then it's likely that there's a problem with the alternator, if it’s not further into the electrical system.
Battery Dies Quickly After Starting
If the battery is dying soon after you start your car, then it's likely that the alternator isn't charging it correctly. This can be dangerous because your battery could die while you're driving, which can leave you stranded, and it's also worth noting that your accessories, if powered by electricity, will also become disabled until the electrical system is fixed. However, that is only a danger if you can actually get your car to start all the way the first time, and a bad alternator is unlikely to allow this more than momentarily.
You Smell Burning Rubber or Wires
If you smell burning rubber or wires, it's likely a bad alternator symptom. This is because those smells are often associated with the belt and/or battery. Because an alternator uses a belt to drive a pully within the engine, burning rubber smells can indicate improper functioning of the alternator and its component pieces inside.
The Battery Warning Light Comes On
If your battery warning light comes on when you're driving, then it's time to get the alternator checked. This is a sign that there's a problem with the alternator and it's not charging the battery correctly. One of the especially telling signs of a bad alternator is flickering of that battery light, as that is a reliable indicator that the specific voltage from the alternator is not consistent, which aligns with the symptoms of a bad alternator.
Your Accessories Are Slow or Not Working At All
If you find your vehicle's windows are slow or sluggish, or if your windshield wipers take a little longer to make a full sweep across the windshield, the inconsistent electrical charge from a bad alternator might be to blame.
