on display there is no any error number, second truck was ok untill few days before.
It sttoped by itself and there is no lifting, side shifting functions. Steering is normal, driving functions are normal. I am getting oil to hydraulic block under right leg, you can hear that electomotor and hydraulic pump is turning on while you give command on jojstick, but electromag ventils are not relasing oil.
But two fuses (i think 2,5 A) below jojstick box are dead. I think that this truck is with contactors hyd

thanks

is there any history to this truck? did someone change the logics board?
how many contactors does this unit have, some of these trucks were built with contactor hydraulics and some were built with chopper hydraulics, and the controller must have the correct eeprom in the logics board.
no other codes?
