What Are the Effects of a Car Power Disconnection?
2 Answers
The effects of a car power disconnection include: 1. Causing unstable engine idle speed; 2. Reducing the actual fuel injection volume; 3. Weakening the ignition energy; 4. Making it impossible to deactivate the anti-theft alarm; 5. Locking the audio system; 6. Causing abnormal operation of related systems. Methods for car battery maintenance: 1. Avoid using in-car electrical equipment for extended periods after turning off the engine. For example, forgetting to turn off the headlights after parking at night can lead to the engine failing to start the next day, largely due to the battery being completely drained from the lights not being turned off in time, which may significantly reduce the battery's performance; 2. When starting the engine, the battery discharges with a high current. However, prolonged high-current discharge can severely damage the battery. Each start attempt should not exceed 5 seconds, and if a second attempt is needed, there should be a 10 to 15-second interval in between.
Last month, my car experienced a power loss, causing all electronic devices to reset. The dashboard warning lights all lit up, the engine management computer reverted to default settings, and the idle speed suddenly became unstable. During rapid acceleration, the throttle responded sluggishly. After starting, the anti-theft system's auto-lock function was mistakenly triggered, requiring key reprogramming to unlock, and it almost failed to start. The air conditioning preset temperature reset to zero, blowing only cold air, freezing me in the middle of winter. The car navigation map got stuck on an old version, and the Bluetooth device list was cleared, requiring manual reconnection of the phone, which delayed my schedule. It's recommended to take a short trip immediately after such an incident to allow the system to automatically relearn and reconfigure, avoiding laziness. Regularly check for loose battery terminals, as accumulated dust and corrosion can easily lead to poor contact; otherwise, frequent power loss accelerates circuit aging.
