The alternator is a very important part of your vehicle’s operation. When the vehicle is running it is producing electricity that powers many of the various systems in your car. Extra electricity it produces is than stored in the battery to help get the car started the next time you need to go somewhere. If the alternator completely fails your battery will quickly be drained of its power and you won’t be able to go anywhere. Before it gets to that point you may experience some of these common signs of alternator trouble.
Problems with Electrical Systems
The alternator provides power for many electrical components of your vehicle including power doors, windows and seats, the radio, infotainment systems and more. If you begin to have trouble with various systems it may be because the alternator can provide enough electricity to power them.
A dying alternator will not be creating as much electricity as it should. This may mean that it won’t be able to completely charge the battery, which will result in slow cranking of the engine when you try to start it.
Do your headlights seem more dim than normal? There is a good chance is because your alternator is failing, since it is what provides the power to keep them bright.
Strange Rattling Sound During Driving
Odd rattling noises that occur while your engine is running can indicate several different problems. One of them however may mean that the mounting bolts that hold the alternator in place have come loose. This could cause damage to the alternator, as well as surrounding parts and even cause issues for the drive belt.
If you’re positive you didn’t leave the lights on or keep the radio on too long with the car off but you have found your battery to be dead, there’s fair reason to believe your alternator has failed and will need to be replaced.
