Questions and answers
why red light and yellow light flashing together and there is buzzing sound in charger
When the red and yellow lights are flashing together on the JHCD CD4212-2 charger, it indicates two possible issues:
1. Red lamp flashing: The output is open-circuited, the battery connections are not secure, or there is a polarity reversal or short circuit. There will be no output.
2. Yellow lamp flashing: The battery is aging or the output cable is connected with reversed polarity.
The buzzing sound is not specifically explained, but it may be a result of incorrect connections or internal electrical issues.
To troubleshoot:
- Check all cable connections for security and correct polarity.
- Ensure the battery is not aged or damaged.
- Correct any reversed connections.
This charger is only for maintenance charging and should not be used for initial charging.
