kus water gauge wiring diagram
KUS water gauge wiring diagram: The function of the water temperature gauge is to show the working temperature of the coolant in the engine cylinder head water jacket. The water temperature warning lamp can light up when the coolant temperature rises to close to the boiling point (such as 95~98 ℃) to attract the driver's attention.
The electrical instruments of common automobiles mainly include ammeter, fuel gauge, water temperature gauge, oil pressure gauge, etc. Its function is to identify and indicate the performance and status of all relevant parts, and provide basis and guidance for correct use and maintenance of the engine. In order to ensure the normal operation of all instruments and accurately indicate the performance and status of all relevant parts, they must be used correctly and maintained in a timely manner. The sensor of the water temperature gauge is a thermistor sensor. Screw onto the engine cooling channel. The thermistor determines the current flowing through the coil winding of the water temperature gauge. This drives the pointer of the meter to swing. Many automotive engine cooling systems use special coolant. The ECU measures the temperature of engine cooling water according to this change. The lower the temperature, the greater the resistance; On the contrary, the resistance is smaller. The ECU measures the temperature of engine cooling water according to this change, which is used as the correction number of fuel injection and ignition timing. To put it simply, we can know the current running state of the car, stop or move, or how long it takes to move through the temperature of the engine water temperature.
Connection method of automobile electronic water temperature gauge:
1. There are three lines of the water temperature gauge, including the main line and the auxiliary line, as well as a signal line. The signal line controls the grounding wire. After the power supply line of the water temperature gauge is connected, the signal line grounding meter will rise;
2. Finally, connect the two plugged water temperature sensors. One end is connected to the signal and the other end is connected to the ground. The signal wire of the meter is F or S or E;
3. There are generally two water temperature sensors: one is the sensor of the water temperature gauge, and the other is a wire, which is used to display the temperature of the cooling water (or coolant) on the water temperature gauge and adjust the fuel supply during startup; The other is a sensor for cooling water or coolant, which is a two-wire sensor. The coolant sensor is used to control the electronic fan. The electronic fan will work when the temperature is high.
Red or red black is connected to the positive pole of the key switch and black negative pole. Two black and white or two-color long wires are connected to the inductor. Install the inductor on the position of the inductor on the original engine.
First of all, a live wire is the positive wire into the positive end of the instrument, and a wire from the negative end of the instrument to the water temperature sensing plug. There is a mark near the pile head of the watch. The black grounding wire and the yellow or white sensing plug wire are marked. You should know that there is only one pile head.
