Signs of a bad alternator<\/h2>\n
Although alternators are considered to be maintenance-free devices, poor care and not paying attention to the right usage of them, can lead to improper function of the alternator or in some cases, failing of the whole system. With proper care, the alternator can even last up to 15 years!<\/p>\n
So, how do you know when the alternator is going bad? Here, we\u2019ll list the most important signs that knowing them will help you find the problems right away to consider repairing or replacing the item.<\/p>\n

Warning Dash Light<\/h3>\n<\/li>\n<\/ul>\n
When the warning dash light turns on, it shows that the output of the alternator is either below or above the specified limit. This sign usually looks like a battery in most vehicles. Some cars may also show ALT (alternator) or GEN (generator). The warning light in the cars can indicate an alternator issue. Some people think it\u2019s one of the signs of a bad battery, but it actually refers to the alternator.<\/p>\n
One of the tasks of the car\u2019s computer system is to monitor the alternator\u2019s voltage output. The warning light is linked to this system which shows if the output voltage is not right. It remains of if there aren\u2019t any problems with this voltage. This light can sometimes flicker instead of remaining on or light up with the activation of different accessories. In all these cases, something is going on with the alternator.<\/p>\n

Dead Battery<\/h3>\n<\/li>\n<\/ul>\n
It\u2019s one of the obvious signs of a bad alternator since it\u2019s the system that charges the battery in your car when the vehicle is running. Although sometimes it can indicate a problem in the starting system too. When the battery is dead, you can\u2019t turn on your car. One of the reasons behind a dead battery could be a bad alternator. Batteries usually help to start up the car and the job for supplying the electricity needed for electrical systems in the vehicle rests on the shoulders of an alternator. So, when the alternator runs into a problem, it may cause the depletion of the battery. To quickly know if it\u2019s the battery that\u2019s dead or the alternator, jump-start the vehicle and quickly remove the jumper cables. Then, if the car runs continuously, the problem is with the battery; but if the alternator fails to charge the system of the vehicle, then the car stops quickly and you need to repair or replace the alternator.<\/p>\n

Dim or Flickering Lights<\/h3>\n<\/li>\n<\/ul>\n
Since alternators power up the electrical system of the vehicles, one of the signs of a bad alternator would be electrical problems such as dim lights or flickering lights, or even extreme brightness (frequent dimming, headlight issues, etc.) Plus, the tachometers and speedometers might stop working as well. You\u2019ll eventually experience all of these problems if you don\u2019t find the problem with your alternator, only the order of the experience differs. Some cars have a pre-programmed list, showing the priority of the electricity distribution when the alternator runs into a problem.<\/p>\n
- \n
- \n
Slow Electrical Accessories<\/h3>\n<\/li>\n<\/ul>\n
Different accessories that are dependent on the electricity to run, can show improper function when the alternator has a problem. These accessories can be sunroofs, stereos, etc. When you demand more electricity from the vehicle, it will reveal that your alternator requires repairing.<\/p>\n
- \n
- \n
Brighter Light<\/h3>\n<\/li>\n<\/ul>\n
When the connections of the vehicle are broken or loose, you can take it as another one of the signs of a bad alternator. Your alternator might show no problems when you have it checked, but the dead battery inside the car as well as other electrical equipment should lead you to consider the possibility that even though the alternator is producing the necessary electricity, it\u2019s either not the right type or doesn\u2019t flow to the right outlet. The electricity that the alternator provides, flows through cables and wires and if these connections, and if they face any problems, this flow can either end or reduce. Then, brighter light will be produced to overcome the resistance that the alternator faces in a loose connection or a broken wire. You may also notice the smell of a burning wire with this sign.<\/p>\n

Bad Alternator Sound<\/h3>\n<\/li>\n<\/ul>\n
You may hear strange sounds from your vehicle, which could be one of the signs of a bad alternator! Some people might not recognize other signs but this one is pretty obvious and can be easily identified. When the pulley of the alternator is not in the right alignment with the serpentine belt, or when the bushing and bearings are worn out, the alternator starts making strange noises like whining or growling-like noises, and that\u2019s how you\u2019ll know it\u2019s time to check the system.<\/p>\n
- \n
- \n
Bad or Loose Belts<\/h3>\n<\/li>\n<\/ul>\n
There might be a loose or bad belt behind the improper function of an alternator. So, check the belt as well when you see signs of a bad alternator.<\/p>\n
- \n
- \n
Bad Smells<\/h3>\n<\/li>\n<\/ul>\n
As we already mentioned, some problems in the alternator overheat the wires and the alternator, creating a bad smell like when plastic is burning. This indicates that you are overusing the alternator. Most of us know what a hot wire scent or burning rubber scent is like. So, make sure your alternator is not overheating and is not under too much pressure. Keep in mind that it can be a sign not a definite diagnosis for a faulty alternator! Other smells such as burning oil might fill your car that has nothing to do with the alternator!<\/p>\n

- \n
No Charge, Low Charge, or Overcharging<\/h3>\n<\/li>\n<\/ul>\n
An alternator that has no charge, shows there\u2019s something wrong with the system. Different issues may cause an alternator to stop charging such as missing or loose fan belt, blown fuse or rectifier diodes, break in the wiring, etc.<\/p>\n
Other issues such as poor wiring connections or again, loose fan belt, might be the reason behind the low charge. And finally, if your alternator is overcharging, it can be due to a poor battery condition or failed regulator or rotor. You\u2019ll know when it\u2019s overcharging by seeing an overly high voltage of the voltmeter of the car\u2019s dashboard.<\/p>\n
