After the high pole light does not light up, how should I fix it

When a high pole light fails to work due to water, the repair procedure should follow the following clear, step-by-step guide, with reference to the information and figures in the relevant article:

First, early inspection
Confirm the power status:
First of all, ensure that the power supply of the high-pole lamp has been safely cut off to avoid electric shock accidents during maintenance.
Check the controller:
Observe whether there is water mark or rust on the wiring end of the controller. If there is, this is most likely the cause of water flooding in the controller and causing damage.

Second, detection and repair
Battery voltage detection:
Use a voltmeter to measure the voltage of the battery. For example, in the 12V solar street lamp power supply system, if the battery voltage is lower than 10.8V, it indicates that the battery is no longer stored and needs to be replaced.
Panel inspection:
Check whether the panel has voltage and current output under normal working conditions. If not, the panel may be damaged and needs to be replaced.
Light source detection:
Power the light source directly and see if it lights up. If the light source is not bright, you need to replace the light source.
Iii. Other possible problems and repair
Line problem:
If it is found that the line is poorly connected or there is a feeding phenomenon, the light may flicker or not light. At this time, it is necessary to replace or repair the poor contact of the line in time.
Installation site problems:
If the place where the high pole light is installed is not enough sunlight, it can not store energy for the battery, and it may also cause the lamp to be not bright. In this case, it is necessary to find a high pole lighting system suitable for the site, or take other measures to improve the lighting needs.

4. Precautions
Safe operation:
Ensure your own safety and follow electrical safety procedures throughout the repair process.
Professional maintenance:
If you are not familiar with electrical knowledge or do not have the corresponding skills, it is recommended to seek the help of a professional electrician to repair.
Use quality products:
In order to avoid the recurrence of similar problems, it is recommended to buy high-quality high-pole lamp products of large brands, so that the waterproof performance and overall quality of the products will be more guaranteed.
V. Summary
Through the detection and repair of the above steps, it should be able to solve the problem that the light is not bright after the high pole light is flooded. During the repair process, ensure safety and choose the appropriate repair method according to the actual situation. If the problem is more complex or cannot be solved on its own, it is recommended to seek professional help in time.
