Machines which are used regularly suffer wear and tear. Same is true for the alternator. If you drive your car or truck regularly, then you want to inspect your vehicle’s internal parts on a regular basis. This way you may avoid serious problems like your automobile stopping in the middle of the road. If you’re aware of alternator problems, then you will know when it is time to fix or replace it. Locating a problem in the vehicle is similar to a doctor finding an illness in a patient. First, you need to identify the symptoms. These symptoms will let you know if the problem is with the alternator or with any other element. Some of the alternator problems can be identified by simply observing the unit closely, while others can be diagnosed by using tools and equipment. Sometimes, it may require opening the alternator. Generally, there’s some abnormal noise, malfunctioning of electric components, or drop in battery charge that indicates a problem.
If you notice any such problem then immediately look for the fault. If the alternator problem isn’t rectified in time, then it can damage other auto parts that are working well. Following are some of the common alternator problems. Worn out Belts is one of the easiest to identify. The belt looks worn out, and it slips. It might also turn loose, affecting the operation of alternator. If the alternator is not running at the standard speed, then it will not provide the perfect voltage. If proper voltage is not available, then the battery will run out of charge. Some alternator problems can be identified by carefully listening when the engine is running. If inside the alternator, the rotor is falling then a grinding noise can be heard. This indicates a faulty alternator. Sometimes, it may require complete replacement of the alternator. Improper voltage can be checked only after disconnecting the battery connection. You will also need a voltmeter to check if the alternator is producing the perfect voltage while running. Voltage also fluctuates depending on the acceleration and RPM. An alternator producing more than the required power can lead to battery overcharging problem. Similarly, low power generation can lead to undercharging of the battery. If you are looking for additional details on starter and alternator rebuild kits, view the mentioned above site.
If you hear unusual cracking noises, then it is likely that the alternator bearings are worn out and need replacement. The sound may also indicate something loose inside the alternator body. The alternator produces AC current, but the car battery and vehicle’s electrical components run on DC current. Diodes are used to alter the AC current into DC current. The alternator won’t provide optimum power if the diodes are not functioning properly. An alternator has many internal components like cooling fan, rotor, diode rectifier, voltage regulator, brushes, coil winding, rotor, stator, and terminals. If something is not working properly, then it will result in poor power production. By identifying these alternator problems, you can easily diagnose the unit. Sometimes, the problem is with all the other elements that are directly or indirectly connected to the alternator.
