boat fuel gauge stuck on empty
The fuel gauge cannot be stuck on empty . The fuel gauge consists of a fuel level indicator with a voltage regulator and a fuel level height sensor. The function of the low fuel level alarm device is to light the alarm immediately when the fuel in the fuel tank is less than a specified value to attract the driver's attention.
There are three causes of fuel gauge failure:
1. The fuel gauge itself. The failure of the fuel gauge itself will lead to the immobility or inaccuracy of the fuel gauge, which can be judged by the fact that the pointer of the fuel gauge still does not sway or the pointer swings randomly when the ignition is turned on for about half a minute, and the inaccurate measurement of the pointer of the fuel gauge indicates that the fuel gauge is faulty; 2. The sensor is faulty. If the sensor fails, the fuel gauge will not move. The judgment method is to clamp the multimeter probe on the two terminals of the fuel sensor variable resistor with R × 1 Ω gear detects the resistance value of variable resistor. If the result is inconsistent with the standard.
It is also possible that the boat fuel gauge sensor float is stuck . When the oil tank is disassembled, a plastic ring is found in it. It is this thing that blocks the float, so the pointer of the oil gauge does not go down. The reason is that the sleeve of the refueling gun fell in when refueling. Try this method: remember to turn off the switch , turn the key , and restart when refueling. Find a stick and shake it at the bottom of the mailbox . If the fault persists , replace it . If the float gets stuck , we can try to top up the fuel, and the fuel level will jack up the float, probably solving the problem of the float getting stuck . You can try to drive on a bumpy road section and let the float fall by itself. This method may not work , but it is worth trying. Check whether the oil pump is damaged. If the oil pump is damaged , the float will also be affected . Replace the damaged oil pump in time. You can buy the fuel level sensor from our company.
