Slide your new switch into the open space on bOb’s side. Then, place the black and red wired end into the battery compartment. There is an indent at the bottom corner of the battery holder, where the wires should sit.   When you’ve replaced everything correctly, lay the wire cover down and install the screw that secures it to bOb. Once the power switch repair is complete, replace the main board, battery, and cover before using bOb again.
