What is the reason for the insufficient power generation of Weizhi V5 headlights

There may be several reasons:1Whether the generator and the engine have good transmission performance, if there is no maintenance for a long time, the belt is seriously worn and the engine power transmission is poor, then the generator can not rotate and work; 2.

Whether the generator is faulty, if the coil inside is broken or short-circuited, the power generation is insufficient or even none3The generator is good, but poor contact with the connecting wires of the battery can also lead to insufficient charging.

Hello! The headlights consume a lot of power, and the idle operation must not be as good as the power consumption, I wish you a happy car! If my reply can help you, please help choose it, thank you very much!

There are several conditions for maintaining engine idling, combined with your situation, the analysis is as follows: 1. When idling, the engine should maintain a stable speed due to low speed, incomplete exhaust, and insufficient air intake, etc., to drive the generator to generate electricity, (at this time, the generator sometimes has to work at full load according to the electricity consumption of the car,) to maintain its own rotational resistance, there must be a large mixing ratio, the working conditions are quite bad, the load is very large, and the set speed considers comprehensive factors, it can not be too high, If the match is too large, it is inevitable that tremors will occur. In severe cases, turn off the heat.

2. The reasons for the unstable idle speed mentioned above, then it is necessary to find out the reason for the excessive load. Because you mentioned that the headlights are obviously unstable as soon as you turn on them, and the fog lights are even more unstable when you turn on them, it means that the generator is working at full load when idling, causing the engine load to be too large and causing instability at idling, because other factors are relatively fixed, only the load of the generator is changing, and this change is increased with the increase of the load of the electrical equipment, we know that the power supply of the car is powered by the combination of the battery and the generator, and the generator speed is low when the car is idling, and the battery is mainly used to provide electricity for the whole car. The headlight is the second load in addition to the air conditioner, if the battery capacity is insufficient at this time, then in addition to the battery power supply, the generator will be forced to generate electricity, and at the same time increase the load of the entire engine, causing the engine speed to drop, which is the fundamental reason. 3. Solution:

Charge the battery, charge according to the specification rush, must be full, full of several standards here do not say, the average person just look at the rush can stop this can not be maintained for a long time, the actual battery power is very low, low speed will cause unstable speed, but also seriously affect the life of the battery. At the same time, because the generator is always working at full load, resulting in high temperature, the formation of insulation aging, insufficient power generation, insufficient charging, forming a vicious circle, but also affecting the life of the battery and generator, 4. The solution is from a more fundamental point of view, one must determine the condition of the battery, what is the situation, and the second is to look at the condition of the generator, and the generator power generation is insufficient, not too much attention, if the generator and the battery are not problematic, you said that this situation can be improved according to the provisions of the charge, Otherwise, the condition of the battery and generator should be checked and replaced if necessary. 5. In actual use, it is necessary to pay attention to the amount of idle speed, and the idle speed is more harmful to the engine, and then try to turn off the headlights and other equipment that uses more electricity when idling, so as to reduce the load and prolong the life of the vehicle.

Check that the generator belt is not loose.

Hello, generally the battery contact fault or leakage, it is recommended to go to 4S to check it.

What is the cause of car engine failure light and insufficient power?

Engine fault lights are used to alert the driver that there may be a faulty engine that needs to be checked for a number of reasons, but we still use the elimination method to check it.

1) Fault phenomenon: when the throttle is slowly accelerated from low speed to high speed, the engine works completely normally, but when accelerating sharply, the engine speed changes slowly, and sometimes there is panting or backfire.

2) Cause of failure: There is an air leakage fault in the air intake system; The oil supply pressure of the system is too low; The ignition voltage is too low; Ignition time is too late; Cylinder pressure is too low or valve clearance is too small; The throttle position sensor is not working properly; The ECU is faulty.

3) Diagnosis and elimination methods and steps: Check whether there is air leakage in the air intake system; Check for high-voltage sparks; Check whether the ignition advance angle is normal; Check the oil supply pressure of the system; Check if the throttle sensor is working properly; Check whether the signal of each terminal of the ECU is normal; Check the valve clearance and cylinder working pressure if necessary.

If the power generation is normal! Just see if you need to take the iron, especially the headlight with the iron point [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, because the headlight generator will increase the power generation, so it will generally affect the power, if there is a problem with the battery, it will also lead to a decrease in engine power, check whether the power generation is enough, and whether there is a problem with the battery, and finally check whether the carbon deposit of the throttle is much, you can clean the throttle and then observe!

Hello! Check whether the generator has enough power generation of 13 volts! If it's not enough, change the generator! Enough is not enough for the engine! There is a virtual tower iron! Install a tie wire [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Nowadays, many vehicles have a battery management system, which detects that the battery is in good health, in order to save energy, it will reduce the amount of power generated by the generator, at this time, measured with a multimeter, the battery voltage is only about 12 volts. When the headlights are turned on, or other electrical appliances are turned on, the battery management system detects that the battery has lost power, and will control the generator to increase the power generation and charge the battery.

As long as the meter does not turn on the battery warning light after the engine starts, there is no problem.

The electricity emitted by the generator of the car is enough for all the electricity on the car, and the problem you said should check all the terminals, whether there is any loose contact and poor contact, if the generator is loose, the above phenomenon will also occur. Generators do not have the problem of aging, unless they are broken, they cannot generate electricity.

Hope it solves your problem.

Check whether the power generation of the generator is normal

1. The power is really insufficient, 2. The computer detects the fault.

Hello, check if the generator is generating normal electricity.

After the headlights of the car are turned on, the power generation will increase, and the current will increase, and the magnetic field cutting resistance of the generator will also be large, which will also increase the fuel consumption of the engine.

If there is no problem with the generator, it is a matter of the battery, and most of the batteries do not store electricity.

It doesn't matter if this is a generator.
