Fault: a Nissan A32 car, the engine flameout during normal driving. When starting again, the starter is slow due to insufficient power and the engine can not start. The vehicle battery has been used for nearly 3 years, and its storage capacity is seriously insufficient. After the battery was replaced, the engine started smoothly, but there was a new problem: the pointer of the tachometer did not move, the charging indicator and the SRS light were not lit. Doubt may be fuse fuse or open circuit fault.
