Cars are a must for us to travel now. When cars have problems on the road, we also need to learn to repair them. In the future, this article will share how to judge whether the car circuit is short-circuited and how to check it.
There are many ways to check the short circuit of the car. The easiest way is to judge according to the habit of using the car. If the car has a short circuit, the car battery will be consumed quickly, even if it is stopped, it will continue to be consumed until the battery is discharged. When there is no electricity, the battery is consumed faster than when there is no short circuit in the previous car. (This excludes the original dark current of the car)
The short circuit of the car circuit is divided into soft short circuit and hard short circuit. If the soft short circuit fuse is delayed, the line will heat up, and the hard short circuit will be blown immediately.
Method of checking the short circuit of the carThe short circuit of the car circuit is generally excluded by using a short-circuit detector. If there is no such equipment, it is only necessary to manually remove it.
The most important point to manually eliminate the short-circuit fault is to understand the route of the car, first remove the wiring of the electrical end, and then check the harness according to the direction of the power supply.
When searching, you can use a test light in series between the power supply and the short-circuit wire, and then pull the wire harness in sections to observe the change of the test lamp.
