Boats are not like cars. Boats do not have a ground system in them as the
body is not metal. You need a ground wire from the battery and a positive
wire from the battery and a positive wire from accessory (or wire both to
positive battery). You must have a ground from the battery. Any piece of
metal will not be a ground.
