I have this lift serial sq50nsybq and the lift wouldn't move but hydraulics would. Local shop supposedly fixed. When it came back it would move but dash would show red light on battery level (even though it was full charge) and no lights on fast/slow button area and hour meter always stays on(even when you turn off switch). They say it's a bad battery. Switched out battery, same issue. Replaced card from junk yard as they don't make original card anymore. Same issue with instrument dash. Any help would be great
