If the Jost Accessories display is non-functional after starting, there are several potential causes. First, check the plug connections for the cabling between the fifth wheel coupling and the electronic display, ensuring all contacts are uniformly engaged and correctly connected. Also, inspect the 1 A automotive fuse and replace it if defective. Next, verify the voltage supply to the connection cable: the white cable should be connected to terminal 15 (+12 V or +24 V ignition ON), and the black cable to terminal 31 (earth). Finally, check the vehicle battery and charge or replace it if it's too weak.
