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.
