Will connecting the jumper cables backwards damage the car?

It may cause some electronic components in the car to burn out. Here is relevant information about motor vehicles: Definition: Motor vehicles are self-propelled vehicles with 2 or more wheels that do not require tracks or overhead lines, capable of operating on roads or off-road surfaces. They are primarily used for transporting people, goods, or performing specialized tasks. China first saw automobiles in 1901, initially referred to as "automatic vehicles," later simplified to "automobiles" due to gasoline engine propulsion. Classification: Vehicle classification is fundamental in various vehicle standard systems. Different standards employ different classification methods, with overlapping references yet distinct emphases. Only by correctly understanding and grasping the basic concepts and applicable scopes of different classification methods, clarifying the connotation and extension of specific definitions, can one accurately apply relevant standard clauses in motor vehicle inspection practice, precisely determine vehicle types, and correctly draw inspection conclusions.
Seeing someone ask whether connecting jumper cables incorrectly would damage the car reminded me of a painful lesson I learned decades ago. Back then, I had just bought my first car and tried to help a friend jump-start his vehicle in an emergency. In my haste, I mistakenly reversed the positive and negative terminals. Sparks flew instantly, burning through the battery and frying the ECU module. Later at the repair shop, I learned that the reverse current had caused a short circuit in the electrical system, costing me a fortune in replacement fuses and controllers. Since that incident, I've developed a strict habit: red clamps must connect to red terminals, and black clamps to black terminals or bare metal grounding points. I now regularly inspect battery terminals and clamp conditions to ensure they're clean and corrosion-free. While jump-starting may seem simple, a momentary lapse can cause serious problems—especially with modern vehicles' sensitive electronics. It's best to thoroughly understand the proper procedure beforehand. Remember: one accident can teach you the importance of safety, so never rush or take risks.
