If the engine in the above vehicle will not start and the display remains dark, the reason may be a faulty earth connection (see marking, image 1).
Image 1.
It is possible that the connection to the earth pin was not secured properly. This means that clean contact between the earth cable and the earth connection pin cannot be guaranteed.
In order to remedy the fault, the connection should be checked, and cleaned if required. The connection must then be screwed together properly, in line with the manufacturer's instructions.
