boat oil pressure gauge not working
If the boat oil pressure gauge not working, it may be that the plug of the oil pressure sensor falls off, the boat oil pressure sensor is broken, or the oil pump is faulty. The pointer of the engine oil pressure gauge does not move. It may also be that the engine oil is too thin, the boat engine oil temperature is too high . When the bearing is loose (especially the crankshaft bearing), the oil pressure will also decrease. In winter, when the lubricating oil is thin, it burns the bearing, but when the oil is thick, it does not burn, but the pointer of the oil pressure gauge cannot rise, It may be that gasoline often leaks into the oil pan along the cylinder wall, diluting the engine oil. However, thick oil is used to temporarily seal the leakage, which will not make the engine oil flush too thin, and has a lubricating effect. Check whether the piston and cylinder wall are worn. Whether the oil pump and oil pipe are in good condition; Check whether the oil pressure limiting valve is suitable. In a word, there must be something wrong with the pointer of the oil pressure gauge. It must be found out and repaired to avoid causing adverse consequences by neglecting everything.
Main reasons: First, the oil viscosity is too low; Second, the filter screen of engine oil filter collector or the filter element of engine oil filter is blocked; Third, the spring force of the pressure limiting valve and the oil return valve is weakened or broken, or the joint surface of the valve is not tightly sealed, resulting in oil leakage and pressure relief; Fourth, the clearance of main bearing or connecting rod bearing is too large; Fifth, the oil pump did not work well.
The failure of "oil pressure gauge does not move" is mainly caused by pressure gauge, sensor and sensing circuit. The troubleshooting idea is as follows: 1. Connect the instrument panel power, unplug the plug of the oil sensor, short the plug, and check whether the pointer of the oil pressure gauge indicates the maximum value. 2. Use a multimeter and a voltage range to measure the plug of the oil sensor for voltage: A. "With voltage", the sensing circuit is good, and the fault is in the oil pressure gauge. Replace it; B. If there is no voltage, the sensing circuit is open for maintenance.
