There are many reasons for abnormal noise from the car alternator. Motor bearings, belts, and brushes will all make noise, so you need to know where the noise is to resolve it.
There is a high probability that the bearing will be noisy. The reason is that the most common cause of this type of failure is bearing noise.
This is usually caused by bearing noise, or the bearing is damaged, causing friction between the rotor and stator or the generator fan blades are loose; If the bearing is noisy or damaged, you can replace a bearing. Replacing the bearing is not a big project, it costs tens to hundreds of dollars. Next, service the generator rotor
Replace the slip ring and carbon brushes. If the fan blade is loose, it's easier, just tighten it. If the car has not expiredwarranty iodine, that would be better, just replace it with a new alternator directly.
Of course, you need to go to the 4S store and ask for a new alternator, and it must be the original one< /p>
Strictly reject products from sub-factories.
You can directly request replacement if there is any abnormal sound problem. The main thing is to see if the article. Replaced is original.
This is a quality problem! Another important thing to note
is that you cannot go to other repair shops for disassembly before that, you can only go to 4S shop for inspection, otherwise the shop 4S will say you disassembled and repaired elsewhere. and will not guarantee repair.
There is another possibility that the car generator belt is making noise. If this happens, it is recommended to check first. If the belt is making noise, this may also be the case. tight ortoo loose. If it cannot be fixed, it can simply be replaced. Do not wait until the fault is serious before checking it, otherwise it will affect your normal driving.
The production method is as follows:
1 Buy a generator with a power of 200 W and a rated speed of about 400 rpm; . You can use ABS. Cut the pipe into strips, then polish them properly after cutting as shown below:
3. Find a metal disk to connect the generator and the blades, which is the hub. the generator;
4. Drill holes in the blades and metal plates. Pay attention to the best time to drill holes, for example:
5. the wheel hub to prevent the screws from blowing away in the wind. It can also be used as a diversion in the sun;
6. Make a stand for the generator, just some wood, then use some wire or iron wire. iron sheets forfix the generator;
< p>7. Make a connecting rod, preferably with a bearing; then make a tower with water pipes, and the wires connecting the generator can finally pass through this hole; the tower and generator and secure them with guyed steel cables. Production is complete.
