What is the reason why the meter light of an electric tricycle does not light up?

If the meter indicator light is not on, first check the power supply fuse of the dashboard.

If the circuit breaker. will need to be replaced. Disassemble the dashboard, the lights are generally at the back of the dashboard, replace the lights that are not lit, and generally the individual lights are not lit to indicate that there is no problem with the fuse and wire, the main reasons are as follows

1. The lamp of the dashboard is damaged and needs to be replaced in time;

2. If the power supply line of the dashboard is broken, there will be an open circuit or a short circuit, which will also lead to the car dashboard.

There is no light up;

3. If the power supply fuse of the car dashboard is broken, there will naturally be no power supply, and the dashboard will not light up.

Precautions in the use of the car dashboard:

1. When the indicator light is on, the odometer should be observed immediately, if the cumulative mileage reaches or exceeds l00,000km, the timing toothed belt must be replaced, otherwise the timing toothed belt may break, so that the engine can not work normally.

2. After replacing the new timing toothed belt, it is necessary to open the rubber plug outside the reset switch on the mileage dial, and press the reset switch inside with a small round bar to extinguish the indicator light of the timing toothed belt.

3. After replacing the new timing toothed belt, remove the odometer and adjust all the readings on the odometer to the 0 position.

Hello, glad to answer for you.

The reason why the instrument indicator light of the electric tricycle does not light up may be caused by the instrument or line, or it may be caused by the motor, which mainly depends on whether the motor is running normally when the power indicator light is not on.

Turn on the motor, pay attention to the motor wire pack, do not rub to avoid causing damage to the wire pack, and do not hit the magnet with iron to avoid causing the magnet to break. If it is the first time, it is best to get the line down and weld it up one by one to avoid welding mistakes, and after welding, first use 502 to stick it with AB glue to avoid the occurrence of unfirm phenomenon. Change the magnet, dip the magnet pay attention to clean the glue on the spindle and the magnet, and use the magnet and the magnet to attract the glue in the opposite direction, and then stick it.

When the power indicator on the dashboard of an electric tricycle does not light up and the motor is running normally. It is possible that there is no voltage between the positive and negative leads of the dial, the connector is not in good contact, or the lead is broken, so you can simply replug or change the cable. When the light-emitting tube of the electric tricycle is damaged, it also needs to be replaced or repaired.

When there is an open circuit on the circuit board of the dial, replace or repair the instrument circuit board in time.

The maintenance and treatment of the instrument indicator of the electric tricycle is a problem that often occurs in the process of using the electric tricycle, and we must deal with it in time once the failure occurs, so as to facilitate the normal and safe use of the electric tricycle.

Two possibilities. One is that the headlight connection line of the three-wheeled electric vehicle is broken, that is, the connection line is broken, because the line is not connected, then it is normal for the headlight to not light up.

There is also a kind of three-wheeled electric vehicle headlight broken, although the line is fine, but the light itself is broken, then the headlight is not lit is reasonable.

The electric tricycle headlights do not light up for many reasons, first check whether there is voltage at both ends of the headlights, if there is, it means that the bulb is broken, there is no voltage, check the headlight switch and plug-in to see if there is any loose place.

Dear, hello, headlights, horns, and other electrical wiring is from a converter out of the electricity, that is to say, the headlights are not on, the horn does not sound to start from the converter, the same, the converter is broken, the car can be driven away. 1. The converter is broken: Normally, the voltage of the car is mostly 60V, and the voltage of the converter becomes 12V, this voltage is going to supply power to the headlight horn, if it is broken, the headlight horn will not get the voltage, and it will not work.

2. The fuse is burned: sometimes we will connect a fuse on the 12V voltage line from the converter, so that the battery will be burned out. 3. There is a problem with the line

That is, the line is broken, whether the line entering the converter is broken, or the line coming out of the converter is broken, the electrical appliances will not work. This can directly measure the voltage of the converter is 12V, if not, it may be that the converter is broken, if there is, it may be the fuse, and the line is broken. 4. Of course, the headlight horn may be broken at the same time, this can be directly replaced, you can know, you can also use a voltmeter to measure whether the voltage is incoming horn, headlights.

5. There are also problems with headlight switches, horn switches, etc., and they will not work. In short, the inspection step is to go to the converter first, and then to replace the headlights and horns directly, which is the fastest way.

It may be a burned filament, a malfunctioning brake light switch or a broken circuit, so go to your repair shop to fix it in time.

There are often car owners who encounter electric vehicles under normal driving conditions, the headlights suddenly do not light up, I don't know what the reason is, now I will teach you a few ways to check the reasons why the headlights do not light up.

The fog lights of the headlights are on, and the near and far lights are not on. From the outside, it is observed that the filament of the bulb is not disconnected, and there are no black burn marks on the wall of the bulb, indicating that the bulb is fine. Open the panel, use the multimeter DC 200 gear to measure the far and low beams and the negative electrode has no voltage, indicating the line problem.

Remove the high and low beam switches and detect the plug behind the switch. Adjust the multimeter to DC 200 gear, measure the middle jack and the jack on either side to see if there is voltage. If there is a voltage, it means that the high and low beam switch is broken, but it does not mean that the headlight switch is broken.

Tricycle lights, usually converted to 12V through a converter, using 12V power supply, observe the front and rear lights of the tricycle, brake lights, if normal, then the tricycle headlights are burned or the headlight switch is damaged.

The electric car can drive normally, but the headlights are not on. How to fix it? Today, I'll give you a detailed answer. In fact, there are generally three reasons why the headlights of electric vehicles do not light up.

1. There is a false connection or poor contact of the line.

Due to the effects of long-term bumps and aging, the connection cable between the EV controller and the headlights may be misconnected or poorly contacted, which will lead to the failure of the EV headlights. That is what the user said, the electric driving is normal, but the headlights are not lit. For this kind of problem, if it is just a poor contact problem caused by the loose wiring of the ordinary wiring, then the user can connect the loose part.

If it is caused by aging and corrosion, then it is necessary to replace the connecting cable to solve the problem of the headlights not lighting.

Second, the headlights of the electric vehicle are damaged.

Secondly, we need to know that there are two types of electric vehicle headlights: halogen lamps and LED lights, and LED lights are usually brighter than halogen lights. Although many electric vehicles already use LED headlights, there are still many models that still use halogen headlights. Therefore, when some users buy electric vehicles, they will ask the store to replace the LED headlights, and although this can make the lights brighter, but due to the lack of matching with the electric vehicle, the lights will be more likely to have problems and be burned.

Therefore, for this kind of problem, the user only needs to replace an original bulb to solve the problem of the headlight not lighting up.

3. Converter failure.

Finally, it is also possible that the converter is faulty, causing the headlights of the electric vehicle to not light up. Why? Because the function of the converter is to control all the light components of the electric vehicle, if it fails, the most direct manifestation is that the electric vehicle lights are not lit and the horn has no sound.

For this kind of problem, the user only needs to replace a new converter to solve the problem of the headlight not illuminating.

In short, the problem of headlights not lighting up in electric vehicles is generally caused by the above three reasons. For users, no matter what the reason, it is necessary to take the corresponding method to solve it in time, after all, it is very dangerous to ride at night without headlights. Of course, I have two suggestions:

Try not to modify the headlights of electric vehicles without permission; When choosing an electric vehicle, try to choose a brand electric vehicle with better supporting facilities. By doing so, you can minimize the probability of such problems occurring.

Hello pro electric tricycle instrument light does not light up may be caused by the following reasons:1Fuse burned out:

It is possible that the fuse is burned out, and the meter light cannot be lit due to the residual branches. You can check whether the fuse under the vehicle battery is burned out or loose, and you can replace the burned fuse with a new one. 2.

Circuit failure: It may be caused by a flash failure in the meter lamp circuit. It is possible to check whether the line connection is loose, the contact is poor, or the fault is caused by a short circuit.

3.Burned-out bulbs: Burned-out instrument lamps are also a common problem.

After a long period of use, the bulb will burn out when it reaches the end of its life or the voltage is too high. You can check whether the bulb of the meter light is broken, and replace the bulb. 4.

Insufficient battery voltage: It is possible that the battery voltage is insufficient and the meter light does not turn on. In the case of low battery power, the vehicle's instrument lights, lights, etc. will be affected.

The problem can be solved by charging the battery or replacing it with a new one.

Summary. Hello, very happy with your question, there are the following points about your problem: 1) Cause of failure.

Judgment of brake handle damage.

Judgment of damage to the speed control handlebar.

Motor damage judgment.

The controller is damaged.

2) Troubleshooting.

Unplug the brake lever socket (normally open brake lever). If the motor is running, it is a brake handle failure, and the brake handle should be replaced.

The 5V voltage of the handle source is normal, detect the signal voltage of the handlebar, turn the handlebar, and the signal voltage should change from low to high. If there is no change in voltage and it is less than 1V, it is a handle fault or a short circuit in the handle line. If the voltage is greater than 1V and the change is normal, detect the motor Hall signal (yellow, green, blue line).

If the voltage of the three-phase Hall signal line is all 5V and the contact is good, the motor Hall is damaged, and the motor or motor Hall components should be replaced.

The dashboard of an electric tricycle lights on, but the motor doesn't spin.

Hello, I have seen your question, and I am sorting out the answer, please wait for a while Hello, I am very happy about your question, and there are the following points about your question: 1) The cause of the failure The brake handle is damaged The speed control handle is damaged The motor is damaged and the controller is damaged (2) Troubleshooting And unplug the brake lever and plug in the sheltered seat (normally open brake handle). If the motor is running, it is a brake handle failure, and the brake handle should be replaced.

The 5V voltage of the Youzhao converter source is normal, detect the signal voltage of the converter, rotate the converter, and the signal voltage should change from low to high. If there is no change in voltage and it is less than 1V, it is a handle fault or a short circuit in the handle line. If the voltage is greater than 1V and the change is normal, detect the motor Hall signal (yellow, green, blue line).

If the voltage of the three-phase Hall signal line is all 5V and the contact is good, the motor Hall is damaged, and the motor or motor Hall components should be replaced.

But sometimes it's normal, and after a while, it becomes like this again, and it is solved.

It may be caused by poor contact.
