how to hook up a oil temp gauge

When the engine is working, If the pointer of the oil pressure gauge is "The outer side of position 0,.Does not move, which is generally caused by the open circuit of the wire from the ignition switch to the oil pressure gauge or the burnout of the internal resistance coil of the sensor and the oil pressure gauge. The general red light is always on, the engine is off, then turn on the ignition lock, remove the wire on the sensor terminal, and the light is still on, indicating that there is a ground connection between the indicator light and the sensor, and if the light is not on, the bulb is burned out or the sensor is faulty. The installation direction of the sensor is correct, you can In order to avoid the hot gas flow of heating bimetallic sheet inside the sensor from directly radiating and heating other components. Because no matter how connected, the current in the circuit remains the same, so it does not affect its indicated value. Oil temperature gauge / oil pressure gauge: after installing the oil temperature gauge or oil pressure gauge, when the pointer cannot be pushed down, it is also necessary to build a ground wire on the sensor to ground the vehicle body. Digital meter: the installation of revolution meter is also relatively simple. Normally, it is also two light wires and two needle wires. Generally, the red wire is connected to the positive pole and the black wire is connected to the negative pole. But the only difference is that there is a signal line to be connected somewhere.

It can be connected to the negative pole of the ignition coil (high voltage negative wire). The revolution meter works according to the magnetic principle. It can receive the pulse signal generated when the initial pole current in the ignition coil is broken, and convert this signal into a displayable revolution value. The greater the number of revolutions of the engine, the more pulses are generated, and the greater the number of revolutions displayed on the table. It can be connected to the signal wire on the crankshaft position sensor. The structure of the sensor on the crankshaft varies with the vehicle model. It can be divided into magnetic pulse type, photoelectric type and hall type. It is usually installed in the front of crankshaft, camshaft, flywheel or distributor. The two lines are generally magnetic pulse type and photoelectric type. It is clear to try connecting the signal line. Three wires are hall type. One power supply line is mostly red -5v, one black line is negative, and the other is signal line.
