Today fellow caravan club member,Don, took time out to come and help me modify the electrical wiring between the batteries and control board. The original wiring was to suit the English and European scene where freedom camping is banned and campers use motor camps with mains power on tap. This cabling was too light and not getting sufficient power from the charger and solar panel through to the batteries. Due to the lightness of the cables the batteries have never been fully charged and the power levels soon dropped rapidly.
After a shopping trip for new 10mm cable and battery fittings we set about running the cable down from the control panel down to the battery box. A couple of extra holes had to be drilled to get the cable into the battery box in the shortest route. At the control board we had to utilise the original connectors as there was no way the thicker cable could be fitted to suitable connectors. A short length of the old cable and connectors had to be retained but this shouldn’t cause any problems.
After testing the system with the volt meter to ensure everything was doing what it’s supposed to do, it was time to reconnect everything. Success and the readings coming from the LCD display panel are encouraging. It may take a day or two for everything to settle down and then we will see how things look then.
