how to wire up a water temp gauge

• 2022-06-29

The water temperature gauge should have three wires . I don't know what color it is . For the time being , it is called a (power positive) , B (ground power negative) and C (sensor 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 commissioning is correct , and the sensor wire can be connected to the temperature sensor probe .

Connect the 12V electronic water temperature gauge to the key and connect the sensing plug to the water channel . External water temperature gauge set , with instrument , harness , sensor and other accessories . The water temperature gauge body is self luminous on a white background , which is more suitable for observing the water temperature at night .

There are four lines in total , one of which is a three line instrument . It focuses on the four line instrument . The four lines are red (key 12V), black (ground wire) , blue (signal line) , white (power is available when the small light is turned on) , and the three lines are short of white lighting lines .

The water temperature gauge can be used to indicate whether the working temperature of the cooling water in the engine water pump is normal . It consists of a water temperature indicator installed on the instrument panel and a water temperature sensor (commonly known as a sensing greenhouse) installed on the water pump of the engine cylinder head .

Install the water temperature gauge (it is required that the screw port of the sensing plug is consistent with the vehicle) directly, and fix the gauge on the workbench without power , regardless of the key switch .

Remove the old instrument and replace it with a good water temperature gauge . Buy an inductive water temperature gauge , connect the water temperature sensing plug - switching power supply - instrument, and fix it . Don't worry about it at all . Don't be short of water after regular inspection . Santana is short of water (antifreeze) and the water temperature is too high . The indicator lights are on . Do not drive when the light is on !
