The reasons why the generator does not produce electricity after Qashqai replaces the battery are:
1. When the car's generator breaks down, the generator normally cannot power all of the car's electrical devices, let alone. charge the battery.
2. Circuit problems, the body wire harness is grounded or the wiring is changed indiscriminately, resulting in excessive current and burning of wires. The reason is that the battery is aging, the power is insufficient, or the car's electrical equipment is not turned off after parking and is still in a state of power consumption, resulting in no power. energy.
Alternator voltage after starting the new Qashqai
Faulty generator belt and tensioner. It is recommended to replace the generator belt of a normal vehicle every 40,000 kilometers. CouldSince it is a rubber accessory, it is likely to age and easily make abnormal noises, which is also the most common.
Regarding the problem of abnormal noises in cars, it is difficult for ordinary car owners to distinguish which are faulty noises and which are reasonable noises. If you go to a repair shop to check for an abnormal noise, only about 20% of cars actually have a problem. There is obviously a difference between the noise of a model equipped with a turbocharged engine and the noise of a naturally aspirated engine; models equipped with a crankcase may also produce noise due to friction, some car owners may be affected by theirs; noise after contacting different cars. Lack of understanding of mechanical knowledge, confusing reasonable abnormal noises with a vehicle breakdowncule. So learn to identify abnormal car noises to avoid wasting time and energy.
How to identify car noises:
In actual work, due to the limitations of working conditions, it is difficult to use special instruments to describe and compare noises cars. For example, the "squealing" noise caused by the dry friction of bearings, the "clicking" noise produced by excessive valve clearance, which is similar to the "clicking" sound of a small hammer hitting the ground in cement, etc.
1. Correctly distinguish between normal and abnormal sounds.
When the car is running, the vibrations of various mechanisms will make sounds of different kinds, but the sound does not mean that the car is defective. In order to avoid unnecessary disassembly, you must first distinguish what is normal. abnormal sounds and sounds. Normal vibrations of various system components(such as noise on the surface of the engine), gear impact noises when changing gears, intake and exhaust noises using gas as a work source, gear meshing noises , etc. are all normal sounds. Abnormal noises (abnormal noises) can be divided into light noises, normal noises and malignant noises according to their impact on car performance. Slight noises, such as the flashing sound of high voltage electrical leakage, the slight rolling noise of bearings, etc., generally have a small volume, the wear degree of the parts is not large, and it does not There is no significant change for a long time. Such defects can still keep the car without repair normal driving.
3. When diagnosing abnormal car noises, care should be taken to create good auscultation conditions and try to eliminate interference from other bruits so as not to affect the accuracy of the judgment.
It is best to consciously amplify or reduce the sound, that is, use a screwdriver or other metal rod as a stethoscope to contact the sound part to amplify the sound , or use a single cylinder to cut off the fire to reduce the sound, to meet the diagnostic needs. The monitoring site must remain quiet to minimize human interference.
Will the 22 Qashqai generator spill oil?
After starting, due to the generator load, the voltage will increase to about 13- 14V
Many vehicles have a voltage detection function by paying attention to the voltage before and after starting. This is also a good way to judge battery life. If the voltage is lower than 12V when the vehicle is not started or lower than 13V after starting, you should consider whether there is a problem.theme with the battery.

Yes.
The 22 Qashqai generator will spill oil. The generator throwing oil is probably due to an oil leak at the bearing. Check Bearings for Wear: Bearings are an important part of the generator operating process. If excessive wear is found, a little lubricating oil should be added when adding engine oil, add it from the top, and the entire amount added cannot. be too much, otherwise it will easily produce electric energy transfer effects.
When it is suspected that the generator is defective, you can perform a preliminary inspection of the vehicle and remove the generator for further inspection without disassembling it. Tools used for testing may be a multimeter, general DC voltmeter, ammetere DC, an oscilloscope, etc. You can also use car bulbs and flashlight bulbs to make your own small test lights, etc., and you can also test them by changing the working status of the car.
