What is the situation when BYD's ignition fuse is blown? What should I do if this happens often?

1, if the fuse models are the same, then the reason for repeatedly blowing the fuse is that there is a short circuit, resulting in excessive instantaneous current and blowing the fuse. Look along the line of No.2 power supply to see if there is obvious current ablation.

This is a serious problem if it happens frequently. Find an experienced repairman to carefully check the plug, the connection state of the line and the connection state of the power supply voltage plug. If the wire plug is not tightly connected, it will lead to this situation of excessive current. Of course, it does not rule out the power load of some relays. This situation of excessive current due to some reasons must be checked patiently and carefully.
