The original normal motorcycle suddenly cannot be started, and the sound of the electric start is not small, but it seems to lose the compression ratio, or it feels like only the movement of the piston, and there is no sound of ignition. When checking the motorcycle spark plug, the fire is weak, the spark is intermittent, and there is no spark. Wait - this is probably due to poor circuit contact, weak connection or loose connection, such as high-voltage package wiring, not only to check the high-voltage package positive wiring, but also to check the high-voltage package's negative wiring, both lines are very important, must ensure positive and negative The poles should be connected to the positive pole and the negative pole of the ground wire firmly and effectively. At the same time, pay attention to the possibility of short circuit and intermittent contact between the positive and negative poles. Don't panic when you encounter this situation, and check the circuit in turn to correct…
