wire gauge voltage drop
I believe many motorists have encountered the situation that the car can't catch fire. In fact, this imagination may be due to the serious power wire gauge voltage drop . So, what if the battery voltage is lower than how much? If you don't start the car, what if the battery voltage is low? Today we'll give you a sister scheme. Car battery voltage is generally 12V, and 12V voltage is not fixed. Under normal circumstances, the battery voltage before starting the car is between 11.8v-12.8v, and the battery voltage after starting is between 13.2-14.8v. If the battery voltage is lower than 11.8V, it indicates that the voltage is insufficient; If the voltage is lower than 10.8V, it indicates that the battery is out of power.
Generally speaking, it is difficult to ignite when the voltage of automobile battery (load) is lower than 9V. But we don't have to worry too much. As long as we drive according to the normal driving for one to two hours, we can return to the normal state. But if it is too serious to start the engine, we need to jump start the generator.
The battery voltage will affect the normal use of the car. If the battery voltage is too low, the car will be difficult to start or even unable to start; If the battery voltage is too high, the battery may be damaged. The battery voltage should be checked at ordinary times. If the battery voltage is insufficient before the car starts, and it is lower than 11.8V, the car will have difficulty in starting. Turn off the electrical equipment and start the car for charging. Once the battery voltage is lower than 10.8V, it indicates that the battery is out of power and the car will not start. At this time, a charger needs to be used for charging. If the battery is used for a long time and the power loss is serious, it will be difficult for the charger to charge. It is recommended to replace it directly.
First ensure that the auxiliary battery is 12 V and the negative terminal has been grounded. Of course, we have to turn off all unnecessary lights and accessories to avoid power accidents.Then connect the jumper cable according to the sequence shown below. Don't connect the positive and negative poles of the cable reversely, otherwise Mars will jump out when connecting, and we have to wrap the cable tightly (fully contact) with the battery to avoid fire jumping on the way. Start the engine of auxiliary battery vehicle and run the engine at medium speed. Then start the engine of the vehicle with a dead battery. Finally, just disconnect the cables in exactly the opposite order.
