Many riders suddenly found that they couldn't start when they turned on the lights. At this time, it may be because there is something wrong with the spark of the car, and they can't catch fire. The reason why the car's Martian stone can't catch fire is to check whether the ignition coil can work normally. If the position is misplaced, the spark will not catch fire. Cheyou can drive the car directly to the 4s shop for inspection and maintenance, and need to replace the Martian stone if necessary. The spark stone of the car won't catch fire. Maybe there is something wrong with the ignition coil. The spark stone of the car won't catch fire. A large part of the reason is that the ignition coil of the car does not work well. Because the ignition coil can't ignite immediately, the ignition is delayed continuously, which will cause the car to get stuck when starting. In addition, if the ignition confirmation is misplaced, the pressure value in the car will also deviate accordingly, resulting in the car not catching fire. If it is not aligned, it needs to be disassembled for re-inspection.

After checking the Martian stone, we need to turn on the power again. The car won't catch fire for a long time, so many friends will send the car for inspection. Is it because there was a problem during cremation? After the inspection, we need to re-connect the power supply, or remove the starter for detection and judgment to see if it is damaged. If it is because the Martian stone is damaged, we need to replace it directly.

You need to take the spark plug out of the cylinder first, then cover the high-voltage wire cap inside the spark plug, iron the inner cylinder with sparks, turn on the power switch, and step on the engine with your feet to see if it can be started, so that you can check whether there is a fire jump phenomenon when sparks appear. If it is found that the Martian stone has been in a state of jumping during the diagnosis, it means that there has been a problem with the internal wiring of the Martian stone, and it is necessary to replace the new Martian stone connection wiring in time, and then see if it can strike the fire normally.

In addition to the above steps, you need to check the low-voltage line, turn on the power switch, and then press the button of the electric horn. If the electric horn of the car can make a clear and loud sound, it proves that the battery in the car is still sufficient, that is to say, the line from the battery to the switch is not faulty. If the computer bar can't ring or the noise is very weak, it proves that the battery inside is insufficient, and the battery should be further checked.

High-voltage circuit diagnosis, check for faults. Besides the low-voltage circuit, check whether the high-voltage circuit is faulty. We can turn on the power switch, first open the contacts of the circuit breaker, then put the ignition wire on the low-voltage column, lead out the conductor through the positive and negative electrodes, and then try the fire through grounding. If there is no spark, there is no fault from the switch to the ignition line, which can prove that the circuit is normal, otherwise further maintenance is needed.

In short, the Martian stone can't catch fire, mainly because there is a high voltage or low voltage fault in the carbon-receiving part of the Martian stone. What we need to do is to check whether these integrated circuits of spark plugs are faulty. If there is any fault, it should be repaired in time. If necessary, the spark plug can be replaced directly to avoid affecting the start of the car and other circuits in the machine, thus interfering with the ignition.
