After replacing the battery for one week, sagitar 2.0 jumped the red light of the battery and the yellow light of the motor, with a sharp sound, and disappeared after the flameout.

When driving, the instrument battery light is on:

1, possible cause: generator failure.

2. Fault point: The generator carbon brush needs to be replaced. At this time, the electric energy of driving depends entirely on the battery, which is harmful to the car!

3. Go to the auto electrical repair shop to check the replacement immediately, and the cost should be within 100. Don't go to the 4S shop. If you go, they will only let you change the assembly.

Another one:

1, don't drive for a long time.

2. The battery needs to be recharged. Your current battery is too damaged by power failure, and it is not enough to charge it while driving.
