Even if you are not a professional in cars, you will find the problem of the car generator (dynamo) one of the easiest problems to identify. In this article, we will present the most important things to look for:
A car alternator (dynamo) is critical to the functionality of your car. This recharges the battery again while driving, ensuring that the battery does not run out.
Simply put, without a working generator, your car will not run.
Knowing the signs of an alternator problem before the car comes to a complete stop on the road is very, very important, so what are the signs?
- Warning lamp illumination
In most cars built in the last decade or so, there is a battery warning light that comes on to indicate that there is a problem with the car’s alternator.
This bulb is connected to a computer system that monitors AC output. You may notice that it either lights up and then goes off or lights up and stays on, indicating a problem with the alternator’s output levels.
Similarly, you may notice that it lights up when you use some electrical accessories in your car, which increases your car’s need for electrical energy.
- Car lights dim and slow electrical systems
The car generator is responsible for providing for the electrical needs of the car.
If it starts to deteriorate, you may notice poor indoor or outdoor lighting.
Other signs include a digital speedometer that stops working and other electrically supplied accessories such as power windows.
- Weak or dead battery
Batteries don’t last forever, but a damaged alternator can cause batteries to die prematurely.
If your car battery is dead and you want to know if the battery or alternator is responsible, charge the battery. Use the cables to charge the battery and charge it from a nearby car, then try to start the car.
If the car is having trouble starting even with a fully charged battery, the problem is likely with your alternator.
- strange smells or sounds
When the generator is weak, the parts that supply it with electricity are affected.
If the belts connected to the alternator do not move freely, the additional friction causes the belt to overheat and smell like burning rubber.
You may also notice strange noises. Parts that are not working properly can produce noise.
Test your generator
If you notice strange smells or sounds, it’s time to have your vehicle checked.
If the alternator can be checked with a voltmeter also called a DVOM or a voltmeter If you are unsure, visit a mechanic and have the mechanic do the job for you.
Turn off your engine and connect its connectors to your vehicle’s battery The red cable connects to the positive pole and the black to the negative pole.
Putting the voltmeter on the AC voltage if it isn’t already should get a reading higher than 12.65 volts.
After that remove the connections then start the car and reconnect the connections carefully, now the correct reading should be about 14 volts.
If not, there is a chance that your alternator may need a replacement.
