In addition to spark plugs, the highest failure rate is the combination coil that generates electricity in the high-voltage coil motor. Inspection Steps: 1. Remove the spark plug and cover it with a high voltage cap. Touch the spark plug to the metal shell of the engine and turn on the machine to check the performance of the spark plug. 2. Check the high temperature! Voltage coil and motor trigger coil. First use a multimeter to measure the impedance, and then measure the voltage of the high voltage coil on the machine. The output wire is red and black, and the trigger coil output wire is blue. and white. There is no multimeter that can detect the short circuit method. Normally there will be sparks caused by the short circuit! 3. Check the output voltage of the yellow and black igniter wires. You can also use the methode instantaneous short circuit. Normally there is a spark caused by a short circuit. Check the igniter, disconnect the black and white wires, and check the spark plug for spark. The black and white wires are the wires from the dead light switch to the power door lock. When the electric door lock leaks, the igniter does not come out. high tension. 4. The input wire of the high voltage box is the yellow and black wire. If there is voltage in the yellow and black wires, remove the high voltage cap and check for sparking in the high voltage wire. the normal distance between the high voltage wire and the motor shell is 0.5-0.2cm. Sparks appear when starting the machine.
What is the reason why the gasoline generator can start but does not produce electricity?
From what you have said, your car is probably burning gas mixed oil (a mixture of gasoline and oilengine). ), and you only use gasoline, so when that happens, it's fortunate that you're not driving fast. If you forcefully drive at high speed, the cylinder will be pulled (the cylinder liner, piston and piston ring are all loaded). . First, I suggest you go to an auto repair shop and let the professionals judge if you are burning mixed oil. If it is mixed oil, change it as soon as possible.
If you can make sure the generator is good and not bad. But the reason why there is no power is because it hasn't been used for a long time, or it has been dragged to death during use. The principle of generator power generation is that wires cut magnetic fields to generate electrical energy. If it is not used for a long time or burns out during use, the magnetic field inside the ggenerator is completely consumed. Without a magnetic field, it is not possible to produce electricity. My method is to suddenly accelerate and decelerate the throttle several times. Generally speaking, power will come out slowly.
