The car alternator is the most active component under the hood of your car. This part is responsible for powering the electrical accessories of your vehicle by ensuring that the car battery is working. If the battery stops working, so will the headlights, the radio and other features that depend on the battery for their power. Therefore, when you turn the key in the ignition of your car and hear clicking noises, it means the car alternator is failing. The noise indicates the replacement of this component is required.
Car alternators are not exactly complicated pieces of equipment. Therefore, in most cases the alternator repair will not turn out to be too difficult. Car owners can perform their own alternator repair in most cases. Qualified technicians are also easily available and they can fix the issues quickly. Car alternators make use of either eyelet or plug type terminals, but the structure of alternators has changed over the years. However, this is, again, not a very difficult issue to deal with it.
Dissembling the car alternator
Before beginning to dissemble the car alternator, you must verify the position of the clock. After this, you will have to separate the drive end assembly of your frame from the ring end by taking out the three bolts that pass through the mechanism. You can then remove the shaft nuts and dissemble the slip ring end frame. After dislodging the fasteners, you are able to lift out individual parts such as the regulator and Rectifier Bridge.
Rectifier Repair
The rectifier is easily one of the most common reasons why there is the need for alternator repair. You can connect any ohm meter with low scales to the bridge terminals and if the reading on both sides is similar, there is a need to replace the rectifier.
Other Cleaning and Repair
It may be necessary to clean the brush holder and if the brushes have been damaged you can replace the brush assembly entirely. It is also possible to clean the slip rings by using your hands to spin the rotor. Use a piece of clean cloth for cleaning everything properly. After this, you must solder the connectors and place the brush holder back inside. Any car alternator that is an AC generator will charge a lot better at lower RPMs. This is the reason why they are preferred over the DC generators. For your car, the alternator issues can be diagnosed via some standard procedures, even though you need to be careful about the symptoms. This is because they may be due to a bad starter or a bad battery, instead of the alternator. Be sure to disconnect the battery cable and then replace your car alternator inside your car.
Cost of Car Alternator Repair
There isn’t any fixed cost associated with car alternator repair. If you hire a technician, the costs will obviously be higher than if you do it yourself. However, you need to have the basic knowledge of what needs to be repaired or replaced. As the alternator has several components, you must be aware of information regarding the different parts. If there is only a belt to be replaced, you can accept the assistance of a car mechanic. However, if the complete alternator is to be replaced or repaired the investments are much higher. You may also want to carry an alternator repair kit in your car in order to be equipped to perform a smaller alternator repair.
