:? I think we still qualify as newcomers - four weeks now! We have three solar panels and two leisure batteries. We tried to use the electric plug in our B694 (1990 model) and nothing happened. We noticed under the drives seat is a "contraption" which links to the batteries. Could someone please explain what the leisure batteries are capable of doing. Do we need any other items to make the plugs work - i.e. an inverter - whatever that is. Any help would be really appreciated.
