Linsheng -Analysis Of Common Problems In Ignition System

linsheng explains that while newer spark plugs can typically last up to 100,000 miles, they can still get dirty or prematurely fail. The ignition wire loses its insulation and the connection to the plug or ignition coil is reduced... these are some of the phenomena you will encounter in the ignition system over time. In this essay, Lin Sheng lists some common problems in the daily use of the ignition system and the corresponding recommendations, I hope they are useful. The presence of water inside can cause spark plug problems, and if this is the case, dry cotton will give you peace of mind. However, if the situation does not improve at all, then it is time to conduct a detailed inspection. If your ignition switch or steering column is heated, if you find corrosion in the system, if not, the connection is loose or the ignition switch wire is damaged, try replacing the ignition switch. As a start to failure, you have several reasons to consult. First, the compression in the cylinder may be too low, and sliding or damaged timing belts are the most common cause. Second, there is not enough fuel in the cylinder. In this case, the fuel pump cannot be opened, or the wear or sensor data may be incorrect. The third reason is the opposite of the second reason. Too much fuel, you need to perform a fuel system stress test and check the scan tool data to help you determine the cause. Fourth, the primary coil will not open or close. Check the positive terminal of the primary coil with a voltmeter or test light to obtain a simple blown fuse or open circuit. Fifth, a short circuit in the secondary ignition circuit may be the result of insulation failure of the secondary ignition system. Sixth, there is an open circuit in the secondary ignition circuit. This will quickly lead to self-destruction of the ignition coil. To repair the ignition, you can follow some fairly simple procedures. When you start using it, remove the fan cover under the hood of the car. First, remember to disconnect the main wire of the ignition coil to ensure safety. You can then perform a compression test and the readings displayed by the compressor should vary between 10% and 15% of the best reading in the service manual. Next, check the spark plug to see if it needs to be replaced. If you really need it, please install a new one. When replacing a spark plug wire, the new wire should be identical to the replaced wire, not the length, not the wire path. Check the dispenser cover, rotor and ignition coil. If you want to replace the dispenser cover, replace it with the rotor. For the ignition coil, make sure the insulation is intact and the connector is solid. Remove the battery and connect the voltmeter to check the voltage. Be careful when you remove it. You should follow professional instructions to solve this problem. Finally, check all connections again to make sure they are tight
