Automotive wiring harnesses serve as the main network of a vehicle's electrical circuits; without them, automotive circuits would not exist. A wiring harness refers to a component formed by crimping contact terminals made from copper material with wires and cables, then molding an insulating layer or adding an external metal casing, and finally bundling them together to create a connected circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. Wiring harnesses have a wide range of applications, including in automobiles, household appliances, computers and communication devices, various electronic instruments, and more. The body wiring harness connects the entire vehicle body, generally taking on an H-shaped form. The wires within automotive wiring harnesses commonly have nominal cross-sectional areas, each with allowable load current values, and are used to connect electrical equipment of different power ratings.

What does it mean when the battery indicator light on the car dashboard turns red?

When the battery indicator light on the car dashboard turns red, it indicates a malfunction in the vehicle's charging system, and immediate inspection and repair are required. The battery indicator light on the dashboard is a charging system warning light, which is connected in parallel between the alternator and the battery. When the alternator is not generating electricity, it only receives voltage from the battery, forming a circuit that illuminates the light. When the alternator starts generating electricity, causing equal voltage at both ends, the light will turn off. Functions of the car battery: 1. Powering the engine starting system, ignition system, and other electrical components of the car; 2. Providing power to the vehicle's electrical equipment when the engine is off or at low idle; 3. Assisting in power supply when the electrical demand exceeds the alternator's capacity; 4. Acting as a voltage stabilizer for the entire electrical system, mitigating voltage spikes and protecting the car's electronic devices.

Where is the most likely place to be hit when a loud scraping sound is heard from the undercarriage?

The most vulnerable parts of a car's undercarriage are the fuel tank, engine oil pan, and the brake system's hydraulic lines. Handling undercarriage scrapes: Generally, cars come from the factory with some protective treatments applied to the undercarriage, which can withstand certain impacts and handle minor scrapes without any issues. If you notice oil leakage or unusual noises after scraping the undercarriage, it is recommended to have the car lifted and inspected at a repair shop. Ways to avoid undercarriage scrapes: You can apply an undercarriage armor coating, which effectively protects against minor impacts and scrapes, shielding the undercarriage. In humid climates, the undercarriage is prone to water accumulation and corrosion, leading to rust and damage. Undercarriage armor can cover exposed metal, forming a protective layer that isolates it from external elements.

What to Do When Volkswagen's Auto Start-Stop System Fails?

There are several reasons for the failure of Volkswagen's auto start-stop system: 1. The start-stop function cannot be used. When the brake is pressed to activate the start-stop system, the gear is in D position without moving. When the brake is released to prepare for moving, the dashboard prompts to use the key to ignite, but the engine cannot start and shuts down, requiring re-shifting to P position and restarting the ignition. 2. Normally starting the car, the first ignition can hear the starter sound, but the engine does not start. The second ignition can start the car, but after starting, it shows an auto start-stop system failure, and the function is unavailable. 3. After testing at a 4S shop, it was found that the starter is faulty and cannot be repaired, only replaced.

How to Adjust the Rearview Mirrors on the Roewe i5?

Maintaining the correct sitting posture is the prerequisite for adjusting the rearview mirrors. If the posture is incorrect, the adjusted mirrors will not function as intended. Below are the methods for adjusting the rearview mirrors: 1. Central rearview mirror: Adjust the left and right positions so that the left edge of the mirror just cuts off your right ear in the reflection. For the up and down positions, place the distant horizon in the center of the mirror. 2. Left rearview mirror: For the up and down positions, place the distant horizon in the center. For the left and right positions, adjust so that the body of the car occupies 1/4 of the mirror's area. 3. Right rearview mirror: Since the driver's seat is on the left, it is harder to control the right side of the vehicle. When adjusting the up and down positions of the right rearview mirror, the ground should occupy a larger area, about 2/3 of the mirror. For the left and right positions, adjust so that the body of the car occupies 1/4 of the area.
