The principle of car wire harness testing
There are a lot of car wire harness connected together, through the instrument will test the results displayed on the computer's display. This instrument is called conduction tester is actually measured a conduction only, in the computer monitor at a glance can see which point there is a problem, no other function, but will be much faster than a multimeter test, professional a lot of. If there is no instrument, then, with a multimeter measurement is possible, as long as your contacts, conduction performance is consistent with the drawings. But the above is the electrical test, there are other tooling size, sealing, anti-aging, temperature cold, environmental protection, and so have a professional test method.
car wire harness is the main body of the car circuit, there is no car wiring harness does not exist car circuit. car wire harness refers to the copper connector made of contact with the terminal (connector) and wire and cable crimp, the outside and then plastic pressure insulator or external metal shell, etc., to form a wiring harness bundle connection components. car wire harness industry chain, including wire and cable, connectors, processing equipment, car wire harness manufacturing and downstream application industries, car wire harness is widely used in automotive, household appliances, computers and communications equipment, a variety of electronic instruments and other aspects.
