combination water temp oil psi and volt gauge

• 2023-09-26

We have combination gauge or gauge panel , which include the water temp gauge , psi oil pressure gauge , volt meter , rpm gauge and others. Combination gauge can save space or looks more beautiful . Water temperature gauge: It tells you the current "body temperature" of the car, allowing you to better choose the driving method, such as driving when the water temperature is low and the car is already hot, or driving when the water temperature rises and the warm air blows out to keep the wind cool, etc. Oil pressure gauge: tells the oil pressure. Voltmeter: This is to remind you, for example, to charge quickly when there is no electricity.

When the engine is working, If the pointer of the oil pressure psi gauge is The outer side of the 0,. position does not move, which is usually caused by an open circuit in the wire from the ignition switch to the oil pressure gauge or the burning of the sensor or internal resistance coil of the oil pressure gauge. The red light is always on, and the engine is turned off before opening the ignition lock. The wire on the sensor terminal is removed, and the light is still on, indicating that there is a ground connection between the indicator light and the sensor. If the light is not on, it indicates that the light bulb is burnt out or the sensor is faulty. The installation direction of the sensor is correct, but To avoid that the hot air flow inside the sensor heating the Bimetal will not directly radiate and heat other parts . After installing the oil pressure gauge or coolant temperature gauge, the two terminals can be wired randomly, one connected to the ignition switch and the other connected to the sensor. Because the current in the circuit remains the same regardless of how it is connected, it does not affect its indicated value. 

Volt meter gauge: The so-called Voltmeter, of course, measures the voltage of the car battery. This meter is the easiest to install. Two power cords and two light strips. Connect the positive and negative poles of the power supply and it will be OK. 

Water temp gauge: When installing the water temperature gauge, connect a ground wire from the screw on the water temperature tee to the vehicle body ground.
