Title: Where to connect the loader stall line - Hot topics and technical analysis on the Internet in the past 10 days
Introduction:Recently, hot topics in the field of construction machinery have focused on troubleshooting and maintenance techniques for loaders, among which "the flameout wire wiring problem" has become a hot topic of discussion. This article will combine the hot content of the entire network in the past 10 days, conduct a structured analysis of the connection methods and common problems of the flameout line, and attach relevant data for reference.
1. Statistics of hot topics in construction machinery across the Internet in the past 10 days
| Ranking | Topic keywords | Search volume (10,000 times) | Main discussion platform |
|---|---|---|---|
| 1 | Loader stall wire wiring | 12.5 | Baidu Tieba, Zhihu |
| 2 | Reasons why the loader suddenly stalled | 9.8 | Douyin, Kuaishou |
| 3 | Flameout line voltage detection | 7.3 | Professional maintenance forum |
| 4 | Diesel engine ECU failure | 6.1 | WeChat community |
2. Principles and steps of flameout wire wiring
1. The function of flameout line:The loader stall line is the key line to control the engine to stop running, and is usually connected to the ECU or mechanical stall switch. The principle is to achieve shutdown by cutting off the fuel supply or ignition signal.
2. Wiring method (taking common models as an example):
| Model | Flameout line color | Wiring location | voltage standard |
|---|---|---|---|
| Liugong 856 | Black/white two-tone | ECU port 12 | 24VDC |
| Lingong L955 | red | flameout relay negative pole | 12VDC |
| XCMG LW500K | yellow | Fuel solenoid valve positive pole | 24V DC |
3. Operation steps:
① Disconnect the negative terminal of the battery;
② Locate the original vehicle wiring diagram to confirm the stall line path;
③ Use a multimeter to detect circuit continuity;
④ Crimp the terminals according to the standard and provide insulation protection.
3. Common troubleshooting table
| Fault phenomenon | Possible reasons | solution |
|---|---|---|
| The engine does not turn off after the key is turned off | The flameout line is open/the relay is stuck | Measure line resistance and replace relay |
| Accidental stalling while driving | Short circuit/poor contact | Check the oxidation condition of the wiring harness plug |
| The instrument displays "Stop failure" | ECU signal abnormality | Use a diagnostic tool to read fault codes |
4. Summary of technical points
1.Safety first:Be sure to cut off the power supply before operation to prevent short circuit from burning the ECU.
2.Tool preparation:Professional tools such as multimeters, circuit diagrams, and waterproof terminal clamps are required.
3.Upgrade trends:The new electric loader has adopted CAN bus control, and the traditional flameout line will be gradually phased out.
Conclusion:Through the structured data analysis in this article, it can be seen that the correct connection of the flameout line needs to be combined with the technical parameters of the specific model. It is recommended that car owners give priority to consulting the original factory maintenance manual, or throughConstruction machinery service platformGet live technical support.
