golf cart voltage gauge
Check the battery power indicator: when the battery power indicator displays green, it indicates that the battery is full and the battery is intact. When the battery power indicator displays black, it indicates that the battery is low and needs to be charged. When the battery power indicator displays colorless or light yellow, it indicates that the battery is basically used up. Measure the static golf cart voltage of the battery: the nominal voltage of the car battery is 12V, and the actual voltage is higher than this. When the engine is not started, the voltage between the positive and negative poles measured with a multimeter should be between 12.5 ~ 12.8v. If the measured voltage is lower than 11.5V, it means that the battery is out of power. If the measured voltage is lower than 10.9v, it means that the battery is basically completely exhausted. Voltmeter: This is to remind you to charge quickly in case of power shortage.
The voltmeter gauge is used to detect the working voltage of golf cart electrical system in real time, and the display range is 0-40.0. The voltmeter starts working when the instrument is powered on. When the engine is not started, the voltage value is usually about 25V, that is, the voltage of the on-board battery; After the engine is started, the generator charges the battery, and the battery is in floating charge state. At this time, the voltage value is usually about 28V. When the voltage value is lower than 18V or higher than 32V, the LCD will display an alarm.
The voltmeter starts working when the instrument is powered on.The people around me have been lying down for three times because of battery problems and generator problems.... I feel more and more that the vehicle voltmeter is a very useful thing. After installation, I can see three voltages.
1. No load voltage of the battery before the vehicle is not started;
2. Battery voltage at the moment of ignition,
3. After the vehicle is started, the charging output voltage of the generator.
Some people say that you can buy something that can see the voltage inserted in the cigarette lighter for 30-40 yuan online. There is no need to lay wires to install this voltmeter. This voltmeter is completely wrong. The kind of voltmeter you said.3008 and most other vehicles will turn off the power supply of the cigarette lighter interface at the moment of ignition. The vehicle voltage has three states:
1. No load voltage of battery (the new battery is real 12V, and the aged battery may be very virtual 12V)
2. The charging voltage after the charger generates electricity (about 14. Once the generator is finished, the vehicle can only rely on the electricity in the battery to maintain operation. Once the electricity in the battery is consumed, the vehicle will lie down)
