What are the symptoms of a car short circuit?

Car short circuits can cause most circuits to catch fire, leading to vehicle explosions. Below is relevant information about cars: 1. Definition of a car: According to the latest Chinese national standard "Terms and Definitions of Motor Vehicles and Trailers" (GB/T3730.1-2001), a car is defined as follows: a non-track vehicle powered by an engine, with four or more wheels, mainly used for transporting people and/or goods; towing vehicles for transporting people and/or goods; or for special purposes. 2. Introduction to domestic car brands: Domestic car brands include Hongqi, Chang'an, Great Wall, Chery, Geely, Roewe, BYD, etc.
My car's last short circuit was really scary. I was driving when suddenly the dashboard went black, the headlights went out, followed by a series of crackling sounds and a burning smell. I quickly pulled over, popped the hood, and saw the wires near the battery glowing red and hot, which had blown the fuse and even made the cigarette lighter stop working. When repairing it later, the mechanic said the short circuit was caused by aging wiring and rainwater seeping in, directly connecting the positive and negative terminals, causing a surge in current. If not dealt with promptly, it could have led to a fire. That experience taught me that when you smell something odd or notice electrical devices flickering in the car, you should immediately turn off the engine and check, not wait until something bad happens to regret it.
As someone who frequently goes on road trips, I once experienced a short circuit on the highway, and it felt absolutely terrible. The car suddenly started shaking, the air vents stopped working, the turn signals wouldn't light up, and then I smelled a burning rubber odor with some white smoke coming from under the hood. After turning on the hazard lights and pulling over, I discovered that the short circuit was caused by poor contact in the modified audio system wiring, which had blown a fuse in the trunk area. Later, when towed to the repair shop, they found that the wiring harness was worn out, and the excessive current had damaged several devices. Since then, I always carefully inspect the wiring connections and fuse box before any long trip—prevention is much cheaper than repairs.
