This should be because there is a generator in the car, which is driven by a belt. As long as the car is started and running, the generator will produce electricity, which will be used to power the energy-consuming elements. the car. If the battery ages, it will no longer have the capacity to store electricity, there will be a power outage situation. When the car loses power, it will not start. There will be a slow sound when starting up, as well as a clicking sound. The lights do not come on and the horn does not sound or emits a slight sound, which are all symptoms of a power outage.
The engine may still run.
Because after ignition, the generator will continuously produce a DC voltage of around 14, which can provide around 1000 watts of electrical power. In addition to charging the battery, it is enough to provide electricity to the entire vehicle. .
Thus, once the car has eWith the gasoline on, remove the battery - the engine will still operate normally.
But the voltage of the entire vehicle at this moment is 14 volts. This voltage is limited by the voltage regulator inside the motor. Once the voltage regulator fails, the voltage will increase significantly, affecting operation. electrical devices throughout the vehicle are a test (and dangerous).
So try not to remove the battery.
