Motorcycle maintenance is a technical work, before 2000, is a very respected industry, but with the development of the market and manufacturing technology, motorcycle maintenance from the beginning through the repair technology to repair, to replace the main parts. This is also for a reason, at the beginning of the motorcycle for the people, is a luxury, accessories supply is not sufficient, motorcycle fault mainly rely on repair, what wash carburetor, carburetor, boring cylinder is often a thing. But later on, manufacturing technology and scale improved, and motorcycles became mass consumer goods, with cheap and abundant supply of accessories. Therefore, when motorcycles broke down, they were usually not repaired, but replaced directly. Even when tricycles broke, they were replaced directly.

After the motorcycle electric spray, motorcycle electric spray system maintenance technology is becoming more and more important, if the maintenance master knows nothing about the electric spray system, then you want to change the piece is unable to start. Take a maintenance case;

A Honda E Film 110 customer, the vehicle has been used for 4 years, in the last half a month, the vehicle often occurs automatic flameout, and there is no rule at all, once this kind of failure, can only rest, or push a distance, ah, can start again. And then the whole day might be normal again. The maintenance station master asked the customer whether the electric spray detection fault light of the vehicle would blink when there was a fault. The user said no, or it would be long bright and would be extinguished once started.

According to the user's description, this is a soft fault, which is not directly reflected in the fault. This kind of fault is the most difficult to accurately judge. The customer has asked two repair shops and said that it cannot be repaired, because there is no computer detection equipment. So, in the event of such a failure, it is no longer like before, the maintenance man to change things one by one, always can fix.

Skilled repair station master also do not need to brush the computer, first of all, you can analyze that the fault must not be a sensor, because the sensor fault is a failure light. According to the user's description, there is no fault light flashing in this car, so it can be inferred that the failure possibility of the actuator is relatively large. The maintenance station master connected the OBD plug with the OBD detection line, opened the electric door lock, and found that the fault light flashed, indicating that the fuel injector was faulty.

The fuel injector cleaning, plug cleaning, after good connection, the fault is not eliminated. Therefore, check whether the power cable is loose, because loose may cause similar fault phenomenon, check the power connector, it is found that a secondary conductor of the positive pole has been broken. But not completely broken, there are several copper connected, and has been rusty, resulting in poor contact from time to time, resulting in a fault, the line is connected, the fault disappeared.

It can be seen that a fairly simple fault, but can let the performance of the electric spray system let people confused, repair the electric spray system or the principle of the electric spray system, circuit, fault phenomenon is quite familiar, it may be successfully repaired, only by replacement has not solved the problem.
