how to wire aftermarket water temp gauge

• 2022-07-21

The power supply of the aftermarket water temp gauge comes from the power regulator . It is not allowed to connect it directly with the live wire of the power supply on the vehicle , otherwise the reading of the indicator will be inaccurate, and even the instrument will be damaged . Do not connect the wire between the water temperature gauge and the sensor to ground for fire test , so as to avoid burning out due to overheating of the heating coil . Ensure that the sensor is well sealed to prevent water leakage from invalidating the sensor .

The aftermarket water temp gauge should have three wires . I don't know what color it is . For the time being , it's called a (positive pole of power supply) , B (negative pole of ground power supply) and C (sensor wire) . During commissioning , connect the positive pole and negative pole of the power supply to both ends of the battery respectively , and short circuit the sensor wire and the negative pole wire. When there is no short circuit, the pointer is at the low temperature. After the short circuit, the pointer is at the highest temperature . This means that the debugging is correct, and the sensor wire can be connected to the temperature sensor probe .

Most old drivers will look at the aftermarket water temp gauge , which is an important data of the working state of the car engine . Generally , when the engine is normal , the indication of the aftermarket water temp gauge is about 90 degrees. When the temperature of the car is too high , it may mean that the engine will have some problems . Then when the temperature of the engine is too high , it will cause faults in other parts of the car , causing a series of problems . Therefore , the importance of aftermarket water temp gauge can be imagined .

If the aftermarket water temp gauge and sensor of the car have been matched and damaged , the water temperature indicator or sensor of other models cannot be installed , and the new parts of the same model should be replaced . If you buy a auto gauge with the same model, it will be easy to wire. Our company's auto meters are all general-purpose, so you can buy them and replace or assemble them with confidence.
