Four ways to deal with short circuit burn out of automobile wiring harness

汽车线束在运用时间长的情况下，偶尔会出现短路或许烧坏的现象，这种情况出现需求马上处理，特别是烧坏，因为线束烧的速度非常快，处理完了很简单整个电气设备都收到损坏。今日浩智小编就来跟咱们说说，遇到汽车线束短路或许烧坏的时分，应该怎样处理?

When the wiring harness is used for a long time, the phenomenon of short circuit or burn out will occasionally appear. This situation needs to be dealt with immediately, especially the burn out, because the speed of wiring harness burning is very fast and the treatment is very simple. The whole electrical equipment is damaged. Today, Haozhi Xiaobian will tell us how to deal with the short circuit or burn out of automobile wiring harness?

一、工具检查法

1、 Tool inspection method

试灯查观念较适合检查导线断路缺点情况。运用暂时试灯法应留心试灯的功率不要太大，在查验电子操控器的操控输出端子是否有输出及是否有满足的输出时尤其要稳重，防庄使操控器超载损坏。最好运用二极管试灯。

The concept of light test is more suitable for checking the wire open circuit. When using the temporary lamp test method, the power of the lamp test should not be too large. When checking whether the control output terminal of the electronic controller has output and whether it has satisfied output, it should be especially stable to prevent overloading and damage of the controller. It is better to use diode to test the lamp.

二、直观检查法

2、 Visual inspection method

当汽车电气系统的某个部分产生缺点时，会出现冒烟、火花、异响、焦臭、高温等异常现象。通过人体的感觉器官的听、摸、闻、看对轿车线束及电器进行直观检查，然后判别出缺点的地址部位，然后大大地提高了检修速度。例如，当汽车线路产生缺点时，常会出现冒烟、火花、异响、焦臭、高温等异常现象。通过直观检查，可灵敏判别出缺点的地址部位及缺点性质。

When a part of the automotive electrical system has defects, there will be smoke, sparks, abnormal sound, scorch, high temperature and other abnormal phenomena. Through the hearing, touching, smelling and seeing of the human body's sensory organs, the car wiring harness and electrical appliances are visually inspected, and then the location of the defect is identified, and the maintenance speed is greatly improved. For example, when the car lines have defects, there are often smoke, sparks, abnormal sound, scorch, high temperature and other abnormal phenomena. Through visual inspection, the location and nature of the defect can be discriminated sensitively.

三、导线跨接检查方法

3、 Inspection method of wire jumper

跨接法即用一根导线将被怀疑有缺点的线路短接后，查询外表指针改动或电器设备工作情况，然后判别出该电路中是否存在断路或接触不良的缺点。跨接是指用一根导线将电路两种的两点连接起来的操作，所跨接的电路两点间的电位差为零，不是短路。

Jumper method is to use a wire to short circuit the suspected faulty line, query the appearance pointer change or the working condition of electrical equipment, and then judge whether there is open circuit or poor contact in the circuit. Bridging refers to the operation of connecting two points of a circuit with a single wire. The potential difference between two points of the circuit is zero, not a short circuit.

四、仪器外表检查法

4、 Instrument appearance inspection method

运用概括缺点确诊仪、万用表、不波器、电流钳等仪器外表来确诊轿车电路缺点的方法。关于电控系统轿车，一般使用概括缺点确诊仪查找缺点码，来确诊车辆缺点规划;再运用万用表、电流钳或不波器有针对性地检查有关电路的电压、电阻、电流或波形，确诊出线束导线的缺点点。

This paper introduces a method to diagnose the circuit defects of car by using the appearance of the instrument, such as fault diagnosis instrument, multimeter, filter, current clamp, etc. For cars with electronic control system, the general defect diagnosis instrument is generally used to find the defect code to diagnose the vehicle defect planning; Then, the voltage, resistance, current or waveform of the relevant circuit can be checked with a multimeter, current clamp or non wave detector, and the defects of the outgoing bundle wire can be diagnosed.

以上四种方法可以在急迫的情况下做参看，当然最好仍是找专业修补人员来帮助处理。轿车线束内部结构凌乱，电线错综复杂，一般没有专业知识比较难处理。希望本文可以帮助咱们，小伙伴们可以动动手指收藏起来。

The above four methods can be done in case of emergency. Of course, it is best to find professional repair personnel to help. The internal structure of car wiring harness is messy, and the wires are intricate. Generally, it is difficult to deal with without professional knowledge. I hope this article can help us, friends can move their fingers to collect.
