1. The battery is charged but the vehicle cannot start. This symptom is probably due to the fact that the fuse responsible for starting the engine is blown. remember not to light continuously.

Or the insurance can be increased to 5A. Basically, if the main power line of the vehicle is installed, there is no problem if the insurance is increased to 5A. Another problem is that insurance often burns out, like headlights. Many of them are not caused by the headlights.
This is caused by too much power production, so the power production system needs to be repaired or the modified bulb has too much power. power. the circuit system is shorted and the fuse has blown after being plugged in.
