1. Charger output problem

-Possible causes: the charger output is faulty, resulting in the failure of normal power supply.

 - Solution:

 - Use a multimeter to measure the voltage at the output of the charger to confirm whether there is 24V output.

 - If there is no output or the voltage is abnormal, it may be an internal circuit failure,
        and you need to contact the manufacturer for repair.

 2. Battery or connection problems

 - Possible causes:

   - Battery is old or damaged and cannot accept charging.

     - Poor contact with charging connector or damaged cable.

   - Solution:

     - Check the battery status for signs of damage or deterioration.

     - Check the charging connector and cable to make sure the connection is secure and not broken.

3. Charger internal malfunction

 - Possible cause: Failure of internal components of the charger (e.g. fan, transformer, capacitor, etc.),
        resulting in loud noise and failure to work properly.

   - Solution:

 - If the noise is coming from the fan, the fan may be damaged or dust may have built up, clean or replace the fan.

 - If the noise comes from the transformer or capacitor, it may be the aging of the internal components, professional repair is required.

4. Overheating protection

   - Possible cause: The charger overheats and triggers the protection mechanism, stopping the output.

   - Solution:

 - Check the heat dissipation of the charger to ensure good ventilation.

 - If the charger overheats, suspend use and try again after cooling down.

5. Noise source analysis

 - Fan noise: the fan may be damaged or dusty, clean or replace the fan.

 - Transformer noise: may be internal components loose or aging, need professional overhaul.

 - Capacitor noise: may be capacitor damage, need to be replaced.

6. Suggested Operating Procedures

 1. Check the output: Use a multimeter to measure the output voltage of the charger to make sure whether it is normal or not.
         Check the connection: Make sure the charging interface is not damaged.

 2. Check connection: Make sure the charging interface and cable are not damaged and firmly connected.

 3. Check Battery: Make sure the battery is in good condition and not aged or damaged.

 4. Clean the heat dissipation: clean the charger fan and heat sink to ensure good ventilation.
