Modern cars have a cluster of instrumentation, sensors and electronic components. That said, a battery wears down after running a complex electronic framework. As part of vehicle maintenance, auto manufacturers and experts recommend replacing the battery every two to three years.
A car owner may have to deal with several electrical issues after replacing the battery in the car. For instance, a sensor malfunctioning, throttle response issues or headlights and horn not working are a few problems after battery replacement.
Here are some common electrical issues after battery replacement and methods to deal with them.
Common Problems After Replacing Car Battery
An intact car battery becomes essential for properly functioning complex electrical systems. For that reason, battery replacement is a must if dealing with issues such as the car not starting or the battery warning light on the dashboard turning on.
Additionally, it is one of the best ways to deal with a dead car battery. However, you may face several electrical issues after replacing the battery in a car.
Let’s learn about these problems and the solutions to these issues.
The Car Doesn’t Start
When you start a car, the battery powers the starter motor. After that, the car alternator keeps the vehicle running. However, a car cranking but not starting is an electrical issue that often happens after battery replacement or the battery is low on charge.
How to Fix it
It happens due to incorrect installation of battery or loose terminals. Moreover, worn-out or damaged terminals are reasons for this electrical issue. In this case, turn off the ignition and check if the terminals require cleaning or proper fitting.
After ensuring everything is in order, you can try starting the car once again. If the problem exists, you can try ways to jump-start a car battery.
Burning Smell
A burning smell from a car is never a good sign. Be it burning of oil, engine heat up or car short circuit – all are signs of worries for car owners. If you have connected the terminals in reverse, it will cause a spark and the burning smell will follow it. Although it is difficult to identify the type of burning smell, you can check under the hood.
How to fix it
When you smell a burning wire, it is due to the reversed polarity. Plus, it is one of the very common electrical issues after replacing the battery in a car. You can fix it by correctly fitting the terminals.
If the smell persists, you can learn the battery testing basics and identify the problem. Besides, it can be due to loose cables that can become a reason behind car battery drain.
Check Engine and Battery Warning Light
If the battery replacement is done incorrectly, it is a cause of the check engine light turning on alongside the battery warning light. Since the car computers (electronic control unit) won’t receive the power, a check engine light indicates the electrical issues.
Moreover, some electrical components may lose their memory due to losing the power. For instance, seat recliners or power seats with memory can become a bit of a hurdle to operate again.
How to fix it
The warning lights on the car dashboard indicate a potential failure and maintenance requirement. You can follow the useful tips for car battery maintenance, which helps in avoiding these electrical problems after replacing the battery in a car.
Windows, Headlights and Horn Failure
Several car components can malfunction due to battery problems. For instance, the window opening and closing button won’t receive the power and won’t work. Similarly, headlights may fail. Besides, a car horn may not work as well.
A car alarm can malfunction, which alerts the drivers when unlocking the car. Some sensors may stop working. All these components will require a proper recalibration.
How to fix it
While you can learn to fix the car horn not working or other electrical components failing, check the car battery terminals first. If the terminals are loose, fix them. Furthermore, you can learn to remove the corrosion from the battery and terminals to avoid these issues.
Quick Battery Drainage
One of the most crucial electrical issues after replacing the car battery is draining constantly. Since battery is among the DIY repairs for car owners, it can become a major issue if not replaced correctly.
How to fix it
Motorists can take their cars to battery replacement centres in Abu Dhabi or the Emirates, where they reside. Besides, a professional can replace the car battery easily without any issues.
FAQs
