2000 suburban voltage gauge reading 15 volts
If car 2000 suburban voltage gauge reading 15 volts , the car battery voltage of 15V is abnormal. The normal voltage is about 11.8v-12.8v. 15V is too high. It is recommended to check what causes it. The battery voltage is too high and may damage the electronic equipment on the car 2000 suburban . After such a situation occurs, it is recommended to check what is affecting it. The high voltage of the battery may damage the electronic equipment on the vehicle. If the battery is dead, the engine cannot be started. When starting the engine, the starter needs to work, the gasoline pump needs to work, and the spark plug needs to be ignited. All of these cannot be separated from electricity.
The starting voltage between 13.2v and 14.8V is normal; When it is not started, the 2000 suburban voltage should be 11.8v12.8v. It is difficult to start when it is 11-12v. It is basically impossible to start when the voltage is lower than 11V. The voltage measured at both ends of the battery should be between 13.2v-14.8v when the vehicle is running, and this value will change with the power consumption of the vehicle. It is normal for your vehicle to have a voltage of 14.4V after startup, because your vehicle has the problem of battery loss. Therefore, the 2000 suburban generator will increase the power generation to charge the battery , so the voltage will be slightly higher. When the battery is full, the voltage will be reduced to about 13.8V. The power supply voltage of the car 2000 suburban battery is 12V , unless the generator power generation is too high, so the voltage is 15V, which is abnormal . It is recommended that you go to the repair shop to check whether there is any problem with the generator power generation !
Whether the 2000 suburban battery is normal depends on its storage capacity . If it is less than 80% of its capacity , it is not normal . The battery voltage is only a general reference . It is not related to the coil and cannot be used to judge whether the battery is normal . In the flameout state , the normal voltage of the car 2000 suburban battery must be more than 12 volts , which is relatively reasonable, but it is not absolute .
