The power supply system of BYD Dolphin Monitor is abnormal and cannot be started.

Inappropriate ignition timing and premature ignition lead to premature combustion and detonation of combustible mixture; Due to the ignition system failure, the spark plug is broken or the spark plug is not firm; The compression pressure of cylinder, the serious wear of piston, piston ring and cylinder lead to the increase of fit clearance between piston, piston ring and cylinder, and the deterioration of sealing performance, which leads to air leakage of cylinder head and reduces the compression pressure of cylinder; Due to poor sealing, the crankcase leaks air, resulting in reduced suction. Solution: Check whether the air filter is blocked and remove it if necessary. Check the throttle opening. When the accelerator pedal is fully depressed, the accelerator should be fully opened, otherwise the cable should be adjusted or the pedal position sensor and accelerator position sensor should be studied. Go to the garage for maintenance.
