marine tachometer gauge water tank gauge

According to the magnetic principle, the marine tachometer gauge generates pulse signals and converts them into speed values that can be displayed. The faster the engine speed, the more pulses generated by the ignition coil, and the greater the speed value displayed on the table. Generally, cars are electronic tachometers with pointer type and LCD digital display type. There are digital integrated circuits in the meters, which drive pointer movement or digital display after calculating the voltage pulse transmitted from the ignition coil. In addition, another kind of tachometer takes pulse signals from the generator and sends them to the tachometer circuit to explain and display the speed value. However, due to factors such as slipping of the generator belt, the value is not accurate.

If the marine tachometer gauge number jumps irregularly, first check whether the flexible shaft connection is disconnected, and then check whether the mileage number increases when starting. If the tachometer does not move. There is no need to repair it, just replace it with a new one. As long as the car starts, the gear in the tachometer will rotate. It will wear out after a long time. The gear in the watch is plastic, and the new one doesn't cost much. The tachometer is generally set in the instrument panel and symmetrically placed with the speedometer.

Generally, there is no marine water tank gauge in the water tank. The water filling pot of the water tank has a water level alarm light. To check the water level in time, a water gauge can be added. What is the low coolant level? If the coolant may volatilize, add coolant to the standard level. There may be a fault, so you need to find out the cause. The gauge shows that the coolant is too low. Open the auxiliary water bottle cover to check the coolant level. If the marine coolant level is lower than the lowest line, add coolant to the normal position. It is confirmed that the instrument gives an alarm due to the lack of coolant. Check all coolant water pipes and interfaces, water tanks, water pumps and other relevant parts of the cooling system. The water pump was found to be leaking. Once the coolant leaks through the water seal, it can be discharged from the drain hole. It is judged that the water seal is leaking and cannot be repaired, so the water pump needs to be replaced.
