Anomaly signs of your car alternator
What is the alternator?
The alternator of the car is essential for its operation.
- It was he who recycles energy battery you consume while driving to the battery to prevent it runs out.
- Without functioning alternator, your car will not run.
- It is extremely useful to detect signs of a faulty alternator before your car breaks downon the side of the road.
So what are the warning signs?
The warning light turns on
In most cars built during the past decade, a drum-shaped warning light illuminates to indicate an alternator problem.
- This LED is connected to the computer system that controls the output of the alternator.
- You will notice that it becomes brighter or illuminates to indicate a problem in the output levels of the alternator.
- You may only lights that will notice when you use some of the electric car accessories, increasing its power consumption.
Lights in low light and slow electrical systems
The vehicle alternator is responsible to meet the electrical needs of the car.
- If it starts to weaken, you may notice lower brightness lighting inside and possibly also outside.
- You might also notice that the speedometer stops working and other electrical accessories, such as windows and heated seats, will operate more slowly.
weak or dead battery
The batteries do not last forever, but a faulty alternator may suggest that they are to change before the hour.
- If your car battery is worn out and want to know if the problem comes from the battery or alternator, charge the battery(which is possible with jumper cables attached to a car running).
- Then try to put the car on. If the car hard to start even with a fully charged battery, the problem is probably the alternator.
Strange sounds or smells
When an alternator weakens, the parts it supplies are affected.
- If the belts connected to the generator does not turn freely, the additional friction heats the belts off a smell of burning rubber.
- You will also notice strange noises: the parts that do not run well or are worn while producing wailing or gnashing.
Test the alternator
If you notice any smells or strange sounds, it’s best to check your car.
- If you are relatively handy, you can even check the alternator with a voltmeter (also called DVOM or DMM).
- Stop the engine and connect his son to the battery of your car (the red wire to the positive terminal and the black wire to the negative terminal).
- Set the voltmeter to DC voltage if it is not already. You should get a value greater than 12.65 volts.
- Then disconnect the son, put the car in gear and reconnect the son, making sure they do not interfere with the belt or motor. The value must now be of the order of 14 volts.
If this is not done, find a good mechanic to change the alternator.
