Hi everyone, I bought a small solar panel a few months ago to keep the battery topped up whilst the caravan is in storage. I have lost the instructions for it and I'm not sure when it's plugged into the 12v socket in the caravan, what setting on the fuse panel to put it on - should I flick the switch to "car", "van" or the middle switch that is neither in order to charge the battery? Caravan is an Abbey Expression 550. Any help much appreciated, thanks Brian
