how to install autometer electric water temp gauge

The autometer electric water temp gauge is used to display the temperature of cooling water or coolant on the water temperature gauge and adjust the oil supply during startup. The cooling water or coolant sensor is a two-wire sensor. The coolant sensor is used to control the electronic fan. How to install autometer electric water temp gauge? When the temperature is high, the electronic fan will work. Connection method of engine water temperature sensor: the water temperature meter has three lines, including main line and auxiliary line, and a signal line. The signal line controls the grounding money. After connecting the power supply line of the water temperature meter, the signal line grounding meter will rise.

Before installing autometer electric water temp gauge, it is necessary to calculate the total electrical load of the vehicle to determine the load of the vehicle when it is working at normal time; calculate the output power of the motor when the engine is idling; calculate the output power of the motor at several different speeds of the vehicle to ensure that the motor can withstand the electrical load of the vehicle when it is overloaded. That is, a certain amount of safety margin should be reserved when selecting the motor. In special applications, it is necessary to consider whether the output of the motor meets the electrical requirements, such as whether it can supply power to the air conditioner and vehicle lighting at idle speed. According to the above results, select the corresponding motor against the motor output characteristic curve family and determine the transmission ratio. When determining the transmission ratio, it is necessary to consider whether the belt wrap angle is appropriate to avoid premature belt damage. The motor must work in parallel with the battery (except for the motor without battery, but the motor without battery must be equipped with corresponding capacitor components). The battery specification matches the motor used. The connection of each conductor must be firm and reliable without looseness and virtual connection.

There is a cover for installing a thermostat next to the water supply chamber pipe of the engine. There is a hole under the cover, and it can be installed there. If it is a wire by electronic induction, the positive pole is connected to the positive terminal of the instrument, and the negative pole is connected to the water temperature sensor. If most of the two lines are directly digital, I won't say more. When installing, pay attention to whether the sensing plug matches with its own engine and vehicle autometer circuit. (it is better to put it in hot water and measure it with a multimeter to see if the resistance value is consistent with the original instrument).
