wiring question


i have a 94 club car i bought. it was not running. the fuse on the charger and the fuse on the receptacle were burnt. i was looking at the wires on the batteries and saw that the green wire coming from the battery going to the forward reverse switch is attached to a negative post on the battery. the wiring diagram shows the green wire coming from a positive post. my question is is the wiring wrong and could that have caused the fuses to go out. or is this correct wiring? there is also a white wire coming from the same location but goes to the charger receptacle. any help willbe greatly appreciated
