1. The motor coil has poor contact or short circuit.

2. The carbon brush of the motor is worn or has poor contact.

3. The internal parts of the motor are faulty.

Solution: The motor needs to be disassembled to check and replace the faulty parts.

2. Gear failure
The gear inside the electric wrench is a key component that transmits power to the working head. If the gear fails, the electric wrench will not work properly. Possible reasons are as follows:

1. The gear is damaged or broken.

2. The gear shaft is worn or falls off.

Solution: The electric wrench needs to be disassembled to check and replace the faulty parts.

3. Battery failure
The battery of the electric wrench is a key component that provides power. If the battery fails, the electric wrench will not work properly. Possible reasons are as follows:

1. The battery is low.

2. The battery has poor contact.

3. The battery is damaged internally.

Solution: You can try to replace the battery or clean the battery contacts. If the problem persists, you need to replace the faulty battery or repair the internal battery problem.

4. Other reasons
In addition to the above three common reasons, there are other possible faults that may cause the electric wrench to not rotate even though it has power. For example: switch failure, circuit board failure, etc.

[Conclusion]

There may be many reasons why the electric wrench battery has power but does not rotate, which requires specific analysis of the specific situation. When using the electric wrench, regular maintenance is required to detect and solve the fault in time. If the problem cannot be solved by yourself, it is recommended to seek professional repair or replace the electric wrench with a new one.
