Hi, guys. Looking for Zapi fault code list for Combi SEM-2 controller. This units are used in Mitsubishi and Caterpilar electric trucks, maybe somwhere else. Have problem with Cat EP12KRT - display fault AL6 on dash and nothing happen(no drive,no hydraulic). Diagnostic LED diode at controller gives 5 blinks. Read somwhere its down to power conntactor or isolator swith, but checked all from batt to main conntactor and seems to be fine. Batt is charged, voltage OK. Are someone know is the main conntactor powered by board or straight from key switch, as there is no power to coil.Seat switch is bridged. Any advice welcome. Cheers. Zygmunt.
