battery voltage gauge on dash
Our company can provide battery voltage gauge , also can provide the dash . The voltage gauge can support 12v or 24v . Check the battery indicator: when the battery indicator displays green, it indicates that the battery is full and the battery is intact; when the battery indicator displays black, it indicates that the battery is insufficient and needs to be charged; when the battery indicator displays colorless or light yellow, it indicates that the battery is basically used up.
Connect the voltmeter in parallel with the electrical appliance, 12 V or 24 V. It is the voltage of the battery. When connecting, do not connect it firmly. Try the direction of the voltmeter number with the connecting wire. If you go up, it is right to fix it. If you don't turn the two wire ends upside down. Be careful to move quickly or you will burn your dash panel .
If the positive and negative lights of the voltmeter are on while the car is running, it must be a problem with the charging system. The most common problem is that the generator has a problem. The carbon brush of the generator is worn, which leads to insufficient power generation, and the red battery fault light is lit. Go to the repair shop for repair. The car may break down on the road after a long time . The car battery is dead, and the battery indicator on the instrument panel is always on. The figure of the battery indicator is: a symbol like a battery, with a plus sign and a minus sign above the symbol. Under normal conditions, it should be on during self inspection and off after startup. If the battery indicator is always on after startup, it indicates that there is a problem with the battery. It should be noted that if there is a problem with the car's generator, this indicator will also light up .
When the car battery is not connected to any electrical components and has no load, it will also lose about 1% of the power every day, which is the self discharge rate of the car battery. If the vehicle is parked for a long time, it is recommended to remove the negative electrode of the battery to avoid battery power deficit. In addition, during the long-term parking of the vehicle, it is necessary to start the vehicle regularly. It is better to start the vehicle every other week to make the vehicle idle for a period of time, so that the internal generator can charge the battery.
