Generally, the voltage of automobile generator is between 13.8-14.3V . Of course, the car with 24V battery is about 28V. This is because the generator is controlled by a regulator. If the regulator is removed, it can be much larger. The output voltage of automobile generator is generally about 13.7v to 14.5V.
Method of detecting generator:
1. Prepare a multimeter.
2. Adjust the gear to DC voltage and select 20V position.
3. Open the car cover and find the positive and negative poles of the battery.
4. Then the red probe is connected to the positive electrode and the black probe to the negative electrode.
5. Start the engine, and then you can see the number displayed by the multimeter. For example, 14.20 is 14.2v.
It is normal that the voltage of automobile generator should be greater than that of battery.
For example, if the battery is 12V, the voltage of the generator should be between 13V and 14.5V. The voltage is normal. If the battery is 24V, it needs to be about 25 to 27V. For some domestic engines, (motor voltage is 12VDC), the maximum virtual voltage can reach 48V. You'd better take a little load to know. It's normal to take a load between 12-16v Therefore, the no-load capacity is not accurate, the voltage is too high, and the battery life will be shorter Nothing else Generally, the voltage of automobile generator is between 13.8-14.3. Of course, the car with 24V battery is about 28V. This is because the generator is controlled by a regulator. If the regulator is removed, it can be much larger.
The red wire is connected to the positive wire and the black wire is connected to the negative wire. Voltmeter is an instrument for measuring voltage. The symbol of common voltmeter voltmeter is v. there is a permanent magnet in the sensitive galvanometer. A coil composed of wires is connected in series between the two terminals of the galvanometer. The coil is placed in the magnetic field of the permanent magnet and connected with the pointer of the meter through the transmission device. Most voltmeters are divided into two ranges. The voltmeter has three terminals, one negative terminal and two positive terminals. The positive pole of the voltmeter is connected with the positive pole of the circuit, and the negative pole is connected with the negative pole of the circuit. The voltmeter must be connected in parallel with the tested appliance. A voltmeter is a fairly large resistor, ideally an open circuit. The range of voltmeter commonly used in junior middle school laboratory is 0 ~ 3V and 0 ~ 15V.
