1, check whether the battery is installed firmly, and it needs to be checked frequently, including whether the battery connecting wire and movable connector are firm and whether the line and connector are in good contact.

2. Otherwise, when the car runs in bumpy road conditions, the battery may shake or even fall off and be damaged. If the connecting wire is loose, it may lead to electric spark.

3. The ignition time should be controlled within 385 seconds. If there is no fire once, the restart interval should not be less than 15 seconds. If you still can't catch the car after starting it many times, don't keep igniting for a long time, but look for the reason why it doesn't catch fire.
