Signs of a Bad Car Battery vs Alternator
There are a few signs that can help you determine if it’s your car battery or alternator that’s causing issues.
Your Car Won’t Start
A common symptom of a bad car battery is that the car won’t start or the headlights won’t turn on. It is because the battery provides power to the starter and ignition system. The car won’t have enough power to start if the battery is bad.
The Check Engine Light Is On
The battery provides power to the engine and all the vehicle’s electrical accessories. If the battery is not providing enough capacity, the check engine light will come on.
The check engine light can indicate a number of different issues, but it could also be a sign that your battery is failing.
The Headlights Are Dim
If the headlights are dim when the car is first started, but then they brighten up as the engine is running, the problem is likely with the alternator.
Alternators provide power to the electrical system when the engine is running, so if it is not working correctly, the lights will be dim.
If you are unsure which problem is, it is best to take the car to a mechanic to have it checked out. They will be able to diagnose the problem and tell you how to fix it.
You Hear a Clicking Noise
The alternator is what charges the battery while the engine is running. If it’s not working correctly, the battery will eventually die.
A bad battery, however, will make the car harder to start. If you turn the key and there’s a clicking noise, it’s most likely the battery.
If you hear a clicking noise when you turn the key, it could indicate that your battery is losing power.
Your Car Is Leaking Battery Acid
If the battery acid is leaking from the battery, it is a sign that the storm is terrible and needs to be replaced. If the battery acid is leaking from the alternator, it is a sign that the alternator is bad and needs to be replaced.
If you are having trouble with a dead car battery and alternator, it is important to consult a professional or a car tune up shop to address the issues correctly.
Always Pay Attention
Paying attention to these signs of a bad car battery vs alternator can help you determine whether it’s time to be replaced. If you’re unsure which problem you’re experiencing, it’s always best to avoid caution and take your car to a mechanic.
With a little effort, your car will be back in its top condition in no time!
