thanks swoop223, about the battery, this is new and have more than 75% of his s.o.c., the trouble is only when I use the levers (control circuit) but if I make to work the pump directly of the contactor there are no problem and the traction works fine. the tune up is for checking the parameters in the ev100 card, because i check it and this are to different than the hyster with the same card, capacity, controls and system.
