What happens when the charging display light doesn t light up after welding after the solar light is

When charging, it shows that the light is not likely to have a problem with this cable, that is, it is not connected, and it is also possible that this lamp is broken.

1. The wiring (positive and negative poles) is wrong, the protection circuit starts and cuts off the whole circuit 2, the new battery is out of power, the protection circuit thinks that the battery is over-discharged, and the protection starts to cut off the entire circuit 3. The display light or the light control circuit is broken or you connect the light control line wrong. 1 and 3 you go to check the wiring yourself, 2 remove the new battery and fully charge it with the charger and then install it.

I suspect that your soldering iron is too hot, and the LED is burned, or the cable is burned, so change the LED!

After the solar light is disconnected. What's wrong with the charging indicator not lighting up after connecting? Or which one is not in good contact? It should be that solar energy should be too limited. If the contact is not good, he must not be able to receive it well, and the solar energy society is this. You can look it up.

Hello, friend the charging indicator light does not light up after welding after the solar light is taken off, this may be the charging indicator light connection. If it's not good, I hope it can help.

After the solar energy is taken off, the charging display light does not light up after welding, it may be because they are not fully connected, and it may not be able to brighten.

This means that the bulb in your motherboard may have this poor contact, which is why it will appear.

The welding method of solar energy and wire is best to choose the Western Han Dynasty. The normal operation of the equipment can be guaranteed.

Hello, that means that the welding has not improved his wiring, that is, the wiring is still not connected, so it is not lit.

The reason why the charging display light does not light up after welding after the solar lamp is connected may be caused by damage to the bulb during soldering.

It seems that the welding charging display light is not on after taking it off, what's going on? Is it power wiring?

Hello dear ! 1. Be cautious in detecting the controller of the solar street lamp, which is the core of the solar street lamp. The red light indicates that it is charging, flashing indicates that the battery is fully charged, if it is a yellow light, it means that the power is lost, and the light cannot be turned on normally, at this time, it is necessary to detect the battery voltage of the solar street lamp, if the battery is normal, then replace the new controller to see if it is normal, if it is normal, it is basically determined that the controller is broken.

If the light is not on, detect whether the wiring has fallen off. 2. If the controller fault is ruled out, the next step is to detect whether the solar panel can be charged, usually the situation that cannot be charged is mainly manifested as there is voltage and no current. At this time, it is necessary to check whether the battery plate joint is welded, whether there is current in the aluminum foil on the battery board, if there is no current to hide the hand, it is basically concluded that the battery board has been scrapped.

If there is current on the solar panel, also pay attention to whether there is snow cover that cannot be charged. 3. The battery is also a link that is prone to failure. The batteries used by many manufacturers are not waterproof, which leads to a short circuit between the positive and negative electrodes after the battery enters the water, resulting in unstable voltage.

During the test, carefully observe the change of battery voltage with the depth of discharge, and replace it with a new one if it cannot be used normally. 4. Finally, check whether the line is damaged. If the insulation layer is worn and the current is conducted through the lamp pole, it will cause a short circuit and the lamp will not light up.

Summary. 1. It may be caused by damage to the bulb, or because the battery board is insufficient or the battery board is damaged, or because the positive and negative poles of the battery board are not connected correctly, or because the line is broken or the line connection is loose. 2. If it is caused by the damage of the bulb, then the damaged bulb should be replaced with a new one.

If the battery is low or damaged, the battery should be replaced with a new one. If the positive and negative poles of the battery plate are not connected correctly, the positive and negative poles of the battery plate should be reconnected correctly. 3. If the solar lamp does not light up because the line connection position is loose or disconnected, the line in the loose position should be reconnected, and the loose position should be wrapped tightly with adhesive tape, so as to avoid loosening again.

The solar lights charge normally, but they don't light up.

Oh my God, you've said a great job! Can you elaborate on that?

1. It may be caused by damage to the bulb, or because the battery board is insufficient or the battery board is damaged, or because the positive and negative poles of the battery board are not connected correctly, or because the line is broken or the line connection is loose. 2. If it is caused by damaged bulbs, then it should be flushed to replace the damaged bulbs with new ones. If the battery is low or damaged, the battery should be replaced with a new one.

If the positive and negative poles of the battery panel are not connected correctly, the positive and negative poles of the battery board should be reconnected correctly. 3. If the solar lamp is not lit because the line connection position is loose and disconnected, the line in the loose position should be reconnected, and the loose position should be wrapped tightly, so as to avoid loosening again.

Hello, I know the co-mentor Xiaoyu, and I'm happy to answer for you. The solution to the high energy light not lighting in the early sun attack is as follows: 1. Detect the solar street light controller.

Red represents charging, flashing represents full power, yellow represents insufficient power, can not be used normally, then you need to test the battery voltage of the solar street light, if the battery is normal, replace the new controller, if it is normal, it is basically determined that the controller is broken. If the light is not on, then check if the wire is falling off. 2. If the controller is troubleshooting, the next step is to check whether the solar panel can be charged, which generally cannot be charged, and generally appears in the form of voltage and no current.

At this time, it is necessary to check whether the battery board is connected well, whether there is current in the aluminum foil on the battery board, if not, it can basically be judged that the battery board has been damaged. If there is current above the battery board, also be careful that it is covered by snow and cannot be recharged. 3. The battery is also a link that is prone to failure.

The batteries used by many manufacturers are not waterproof, and once in the water, the positive and negative electrodes of the battery will be short-circuited, causing voltage instability. During the test, it is necessary to carefully observe the change of the battery opening voltage with the depth of discharge, and if it cannot work normally, it should be replaced in time. 4. Finally, check whether the line is damaged.

If the insulation is worn out, the current is transmitted through the pole, which will cause a short circuit in the lamp, causing the bulb to not work properly. I hope my answer is helpful to you. Have a great day.

1.Usually, when the solar panel is turned on, the solar charging indicator does not respond, indicating that the controller is damaged and needs to be replaced. Or the solar panel access line is open, and the line needs to be detected.

2.There are generally three solar lamp controller indicators, which indicate solar panels, batteries and light sources. Under normal circumstances, the indicator light of the solar panel is often bright or flashing when charging.

When discharging: the battery indicator light is always on. Flashes when power is lost.

When discharging: The light source indicator is always on. Flashing usually indicates a faulty key.
