boat fuel gauge inaccurate
The reasons for the boat fuel gauge inaccurate are: poor contact of the fuel position sensor or severe wear of the sliding resistance; Abnormal circuit or aging of electrical components; Abnormal deformation of oil tank or support; Virtual connection and open circuit in the engine; The grounding wire of upper oil level sensor and oil pump harness is loose. The boat's fuel gauge consists of a fuel level indicator with a pressure regulator and a fuel level sensor. Its function is to give an alarm immediately when the oil volume in the tank is lower than the specified value, so as to draw the attention of the driver. The fuel gauge is used to indicate the amount of fuel in the tank of the ship. It can be a pointer or a digital display.
The boat fuel pump needs to be replaced, because the gasoline pump assembly is composed of the gasoline pump and the gasoline filter, and is installed in the fuel tank. If the captain drives when the fuel alarm indicator lights up, the temperature of the oil pump will be too high, which will affect its service life. It is recommended not to refuel until the ship's fuel indicator lights up.
In this case, it is necessary to check whether the circuit connection of the oil level sensor is loose and whether the plug is reliable. Use a multimeter to check, repair the circuit, ensure reliable connection, and then return to normal. Timely repair and maintenance ensure stable, comfortable and safe driving.
The current flowing from the transmitter passes through a resistor, which may surround or be located near a bimetallic sheet. The bimetallic plate is connected with the pointer of the fuel gauge through a connecting rod. When the resistance increases, the current through the heating coil decreases, so the bimetallic sheet will cool down. As the metal plate cools, the metal plate will straighten so that the fuel gauge will point from full to empty. The fuel gauge is mainly composed of two parts: the sender that measures the fuel level in the fuel tank and the fuel gauge that displays the measurement results to the driver.
It is also possible that if the boat instrument main board has an electronic fault or the oil gauge display pointer is stuck, the instrument will not display. Solution: In this case, maintenance and replacement of instrument accessories are required.
