    EX120-3 is a 24 volt electrical system. @LACHAU posted a link to a EX120-3 technical manual in this thread, HeavyEquipmentForums . The electrical schematic and wiring diagrams are on the last few pages.

    There's a fuse on the battery side of the battery disconnect relay for the ignition switch power.
