Hi everybody
I solved all the problems with Jungheinrich EFG DF 1.3
After I checked lift board to determine it was fine I recommended to the forklift owners to make a good maintenance of all parts on the hood (both traction motors, hydraulic motor and the hood). During the maintenance they detected that right traction motor have one of the carbon brushed broken (accordingly to the error showed by LISA) they replaced it and installed everything again.
I also installed a brand new K1, after connecting everything I started the forklift and remains with error 39 and 83, and then I began to reset Machine type to default one (EFG). After 4 tryouts doing this the boards recognize machine type EFG and Lifting board together with Left traction one began to work fine, right traction board was giving error 14 (No k1).
After a good check to all wires connections I realize that F1 cable from right traction board was unplugged during manipulations to CANBUS cables and because of this the error 14. After re-connecting everything started fine and k1 went on.
The only mismatch during the operation was that local technicians after assembly the traction motors mismatch F1 and F2 cables connections to the motor provoking that when I selected the travel direction right and left were opposed each other causing the forklift to be stopped, but this was fixed quickly and everything went fine.
