no voltage gauge dodge ram 2500
There is no voltage gauge dodge ram 2500 , can add a voltage gauge on it. Our voltage gauge is easy to install. The earliest truck is an ammeter, which indicates the charging and discharging state of the battery: when the power switch is turned on, the car will not be started, and the pointer will slightly shift to the "-" direction; when the lights are turned on or the car is started, the pointer will significantly shift to the "-" direction, and after the car is started, the pointer will slightly shift to the "+" direction.
However, the dodge ram 2500 is generally not equipped with ammeters, but with voltage gauges. Diesel cars are generally 24V (gasoline cars are generally 12V). When the power is turned on and the car is not started, the pointer points to 24V, which is the voltage of the battery. When the engine is idling, the pointer should be greater than 24V. At this time, it represents the output voltage of the generator (generally about 26V~28V). Observe this meter to know the working conditions of the battery and generator of the car.
Now the truck has a light with the same function as the ammeter, a battery like red light. When the key is turned on and the car is not started, this light is on, indicating that the battery supplies power. Once the car is started, this light is off, indicating that the generator supplies power.
Potentiometer is also called voltmeter. Indicate the voltage in the circuit. Before starting the vehicle, it will start to work. If there is no instruction , people will check the circuit system through this condition. Voltmeter is a typical contact absolute angle sensor with a sliding contact on a carbon resistor or plastic film . This variable resistance is proportional to the movement position of the angular (or linear) sliding contact . The voltmeter changes the terminal voltage through an adjustable resistor , generally using a sliding rheostat . Voltmeter has linear potentiometer , output voltage is proportional to angular displacement .
The Dodge ram 2500 can be added with a voltmeter . It is not very accurate to connect the cigarette lighter . It is recommended to add a power diode to the positive pole of the battery and then connect the voltmeter in series to avoid unnecessary voltage fluctuation protection.
