fuel level gauge wiring diagram
The wiring method of fuel gauge is as follows:
1. There are two positive and negative wires on the oil gauge, of which the positive one must have electricity and can be connected from the switch lock;
2. The resistance on the oil float is also one in and one out, and then it can be connected in series with the two lines on the oil gauge. The negative line after series connection should be grounded;
3.One of the yellow or blue lines is the positive pole (you can try it separately to see if the pointer of the oil gauge reacts), and the black line may be the negative pole.
The main reason is that there are two wires on the oil meter, one positive and one negative. The positive one must have electricity. The resistance on the oil float is also one in and one out, and then it can be connected in series with the two wires on the oil meter. The negative wire after series connection must be grounded.
Generally, the fuel gauge is located directly in front of the driving position of the vehicle and on the same dial as the water temperature, speed, speed and other indicators. The fuel system is mainly composed of fuel gauge, sensing circuit, variable resistance and buoy. When the fuel tank is full, the resistance value of the variable resistance at one end of the buoy becomes smaller, and the current of the whole circuit reaches the maximum value. At this time, the pointer of the fuel gauge is at the highest position; When the fuel consumption decreases, the resistance value of the variable resistor increases correspondingly, the circuit current decreases, and the fuel gauge pointer also decreases. The automobile fuel gauge has rich functions and advanced functions. It can display the fuel quantity in the automobile fuel tank in real time, and accurately tell the owner how much fuel the automobile consumes and how much storage is left in the fuel tank. The owner also makes a judgment on whether to refuel or how much mileage to drive according to the display of the fuel gauge. The fuel gauge is equivalent to the warning light of automobile life. The fuel gauge is an indicator that can display the fuel quantity on the engine, which is displayed by pointer or number.
