Spark plugs for two-stroke motorcycles are the live wire. Two-stroke motorcycle spark plug connection wire:
1. Connect the red wire to the positive pole, the black wire to the negative pole, and the ignition lock output power to the green wire. There are two extinguisher wires, either positive or negative, and the output and input parts are positive and negative for the ignition system.
2. The yellow and black wires from the igniter are connected to the high voltage box, the blue and white wires, the positive trigger electrode, and the green and white wires. Trigger the negative electrode, white and black wires, connect to the black and white wires of the ignition lock, black and red wires, connect to the generator low voltage output, green wire and wire of earth.
3. There are two extinction wires, whether positive or negative, and the output and input parts are positive and negative for the syignition system. One extinguisher wire is connected to the negative pole of the coil and the other is connected to the positive pole. No sequence required, ammo prevents coil shorts.
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. If there is no multimeter, the short circuit method pecan be used immediately. 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 instantaneous short circuit method. Normally there are sparks 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 voltage. 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.
