Several Knowledge Points on Harness Repair

Several Knowledge Points on Harness Repair
In the work often encountered wiring harness damage, tear, plug pieces broken, lost. Undergraduate units are generally safe and fire on the grounds that the need for new wiring harness. The cost of less three to four thousand dollars, more than ten thousand. High-priced car harness offer more than one hundred thousand. In fact, regardless of the degree of damage, blindly asked to replace the new product, is an improper reason. The design of the harness in the design of the harness, the maximum to achieve the harness safety design.

The measures taken are:

(1) full-time power management module.
(2) Main level safe box.
(3) sub-sub-line relay, insurance films.
(4) set the current inspection and monitoring procedures.
(5) increase the line insulation layer of flame retardant.
(6) The control switch is set at the ground terminal. These measures basically guarantee the normal operation of the line. If there is no rupture of the insulation and accident damage, the harness can be safely operated for more than fifteen years. In order to reduce the burden of maintenance, Volkswagen from the accessories channel, to provide users with all models of the whole car harness damaged parts.
The whole car electrical control switch, are the control loop. That is, the current first to reach the electrical equipment, and then run to the switch, by the switch control ground, into a loop circuit, the light bulb to light, the motor can turn. Injectors, ignition coil, electric thermostat and other electrical appliances, are in the computer module, by the switch circuit control ground start, stop. All electrical equipment before the wire appears exposed bare, there are short-circuit ground caused by the possibility of large current discharge fire. Electrical equipment, even after the wire even exposed bare iron, because the line resistance is large enough, so no large current discharge fire.
In actual accidents, the collision causes most of the line breakage in the front and rear of the body. Front has a light signal, fan motor (12V) line. Collision switch, fan control module, air conditioning pressure switch (5V) line. Radar line, camshaft, crankshaft position sensor information line (1V). The rear has a light signal line (12V), reversing radar line, trunk induction switch line, automatically enter the sensor line (1V).
