1, main relay failure, unable to supply power and oil in time.
2. If the gap is too small, the spark will weaken, and the two electrodes will be connected by carbon deposition, so that the spark cannot be generated. If the gap is too large, the required breakdown voltage between the two electrodes will increase and the ignition coil will bear the load. If the breakdown voltage exceeds the working capacity of the ignition system, the spark plug will not produce electric spark, and the power and oil will be cut off.
3.GPS failure, wiring error or poor grounding of burglar alarm will lead to power failure.
