What to look for in an automotive wiring harness replacement!

With the development of science and technology more and more wiring harness factory produced high-tech products that are used in our days, such as wiring harness tester, on the more complex car wiring harness circuit, if the presentation of shortcomings, with manual judgment is very difficult to find the shortcomings in what place, if the use of car wiring harness tester, then you can deal with these problems. The following for us to introduce the replacement of the car harness.

Sedan wiring harness assembly replacement: a. Appearance check 1, the new type of wiring harness should be common with the type of the original model, wire terminals and wire connection is secure, can be pulled by hand to pull the plug and wire with or without loosening, shedding and other phenomena.　　2, the new car harness and the original car harness for comparison, such as: car harness standards, wire terminal connectors, wire color should be fundamentally common. On the questionable places, you can use the harness tester to test, recognize the car harness intact in the future, before replacement. Second, the car harness installation will be a car equipment plug connector, plugs, sockets and car wiring harness on the socket, plug corresponding. The connection wire and electrical equipment connection, to leave a certain margin, the wire can not be pulled too tight or put too loose. Third, the line check and connect the experiment 1, the line check the car wiring harness replacement is completed, the primary need to check the car wiring harness plug and electrical equipment connection is correct, the battery positive and negative poles are connected correctly.　　2, electrification experiments The battery hitch line can be temporarily not connected, with a 12V, 20W or so of the bulb to do the test light, the test light will be connected in series in the negative terminal of the battery and the frame between the hitch end, closed all the electrical equipment on the car switch. Normal test light should not be bright, otherwise marked circuit has shortcomings. When the circuit is normal, remove the light bulb, with a capacity of 30A fuse, connected in series between the negative terminal of the battery and the frame hitch, do not start the engine, one by one, turn on the car power supply of the electrical equipment, electrical equipment and line inspection, in recognition of the electrical equipment and the line has no shortcomings, take off the fuse, connected to a good battery hitch line.　　Through the harness tester factory on the replacement of the car wiring harness for a detailed introduction, we can use these methods to replace the car wiring harness in the future when the car wiring harness inspection.
