About electric vehicle speedometer,Can a mechanical instrument panel be converted into a LCD instrument panel? First, distinguish the information that needs to be displayed on the mechanical instrument and the liquid crystal instrument.
Mechanical meters: vehicle speed, rotational speed, mileage, water temperature, fuel volume, and some have some simple function settings.
Therefore, if you want to change the LCD meter, it is also very simple. As long as the original signal lines of the liquid crystal come over, they can be identified and can be displayed on the liquid crystal. Therefore, it is recommended that Taobao buy LCD accessories from other factories and install them directly.
Of course, you have to change from a low-profile to a high-profile original LCD instrument, which involves some other signals that the LCD instrument cannot receive (the key is the can signal sent by other accessories), then it will report a fault code or fail to display, etc. If you want to keep the warning light off, it involves the matching of a lot of accessories. Many of them may require high-end accessories. Of course, even if you change the high-end accessories, because many of them have no wires, they will fail. Therefore, this is not realistic.
Generally speaking, the LCD screen can be lit as long as the 12v power is the same as the above, but it is a fault light (because of the missing can signal, etc.).
There are many types of speedometer, such as: electric vehicle speedometer, pulsar speedometer, etc.
