how to fix voltage gauge on 2005 chevrolet tahoe
First, determine the connection position according to whether you want to measure the battery voltage or part of the voltage, select the range and model of the 2005 chevrolet tahoe voltage gauge , and select the appropriate position to fix the voltmeter. The positive electrode of the voltmeter is connected to the positive electrode of the line, and the negative electrode of the voltmeter is connected to the negative electrode of the line.
The car needs to be started normally and the battery needs to have a certain voltage. The car has been stored for a long time, because the battery has a self discharge problem, and a certain voltage will leak. If the battery voltage is lower than 11 volts, many cars are difficult to start under normal temperature. The main reason is that the motor itself needs a certain voltage to reach a certain speed. There is line loss on the line, internal resistance of the motor and internal resistance of the battery. All these will cause low voltage and low speed. When the rotation speed of the motor is too low, the torque of the motor will also drop and the compression force will be insufficient. At the same time, even if the oil-gas mixture is ignited each time, the output power per unit time will be insufficient, and the engine resistance cannot be overcome and stable idle speed cannot be formed .
In the flameout state, when the 2005 chevrolet tahoe battery voltage is 12.15v, the charge in the battery is about 25%; The battery voltage is 12.30 V, the charge in the battery is 50%, the battery voltage is 12.5 V, and the charge is 75%. If the battery voltage is higher than 12.60 V, it can be considered that the charge in the battery is 100%. These data are the data of the new battery, and can only be used for reference. They are not necessarily accurate.
If it is measured when the car is started, it can be considered that the battery is working under load, which is much more accurate than static voltage measurement, similar to measuring the internal resistance of the battery. The voltage is not lower than 11V, so the capacity of the battery is excellent. If the battery voltage is lower than 10V at startup, it can be considered that the battery is in poor condition; if the battery voltage has reached 9.5v at startup, it can be considered that the battery is almost no used . Can fix a new voltage gauge now.
