Diagnosing A Problem With Your Car's Alternator
Posted on: 12 January 2016
As a car owner, it is important for you to know the signs that there is a problem with its alternator. The alternator in your car serves a vital part in its ability to start and run its electrical components. A malfunctioning alternator can lead to premature battery failure, electrical component failures, and the inability to start your vehicle.
Here is some information about alternators and how you can diagnose a problem with this vital part of your car:
The Function of Your Car's Alternator
The alternator in your car uses a process known as induction to change the rotational energy in your car's motor to electrical current. This electrical current is what powers your vehicle's:
- headlights
- radio
- heated seats
- cigarette lighter
- power windows
- windshield wipers
In addition, the alternator is responsible for recharging your car's battery. While the battery is used for current flow while your car is running, it's power is only used to start your car.
Signs of a Faulty Alternator
There are many clues that signal the early signs of an alternator problem, such as:
- ALT or GEN light on dashboard coming on
- dash lights flickering
- headlights dimming when you drive
- trouble starting your vehicle
In addition to the above, you may also hear a loud sound coming from the alternator's bearings if they have become too worn. A burning rubber smell will come from the belt if it has become worn.
How to Test Your Car's Alternator to Confirm Its Failure
If you are unsure if the problem lies with your car's alternator or battery, then there is a simple way that you can test it to determine the cause of the problem.
To test your vehicle, jump start it using a second vehicle and a pair of jumper cables. If the car runs when you remove the jumper cables, then the battery is the root-cause of the problem. However, if the car only runs for a minute and then dies, then the problem is with the alternator. The car dies because the alternator isn't able to charge the battery and properly utilize its power output.
For Additional Assistance
Finally, if you have determined that the alternator is not functioning properly in your car, then it is important that you get your vehicle into the auto repair shop as soon as possible. Failure to act quickly in this scenario can lead to expensive repairs in the future.
