1 The switch is broken (the key ring)
2 The emergency stop on the integrated switch on the right side of the handlebars is deactivated (red button in the shape of a boat)< /p>< p>3 The spark plug is broken
4 The high voltage package is broken (divided into DC and AC). Most imported cars are DC and more than 90% of them have AC wire color.
Usually black**
5 Ignition is cut off (DC and AC) AC line color black and red: ignition coil black and white: extinguishing line blue and white fire: positive trigger coil Green and white electrode: trigger coil, green negative electrode: battery negative electrode and ground wire (and the car. The frame is open, i.e. that it is screwed to the frame or motor.) Black and yellow: high voltage package. domestic DC wire. Orange, red or black is the original thread. The wire coming out of the switch is the ignition wire.e. The others are the same.
6 The ignition coil. is broken
7 The trigger coil is broken
8 The above connectors are loose or disconnected
I hope you are satisfied with my answer
< h3>Why does the car generator have a magnetic field but does not generate electricity?In addition to spark plugs, the highest failure rate is the high voltage coil that generates electricity in the motor's combined coil.
Inspection steps:
1 Remove the spark plug and cover it with a high pressure cap, place the spark plug in contact with the metal shell of the engine and use the engine to check. the performance of the spark plug!
2 Check the engine For the high voltage coil and trigger coil, first use a multimeter to measure the impedance, and then turn on the machine to measure the output voltage. High coil lineThe voltage is red and black, and the output line of the trigger coil is blue and white. If there is no multimeter, the short circuit method can normally be used. tour!
3. Check the output voltage of the yellow and black igniter wires. You can also use the instantaneous short circuit method. 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 fire switch wires for the electric door lock. leaks, the igniter will not produce 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 a spark. the high tension wire. Normally, the distance between the high voltage wire and the motor shell is 0.5 to0.2cm.
The reasons why the car generator has a magnetic field but does not generate electricity:
1. At least three anodic or cathode diodes of the generator rectifier diode are open circuited. ;
2. At least two phases of the stator coil are burned out;
3. The armature terminals are in poor contact or the output is open circuit;
p>4. The line between the generator and the battery cut-off circuit.
