I just take the battery out until i next need to use it. Your right they do drain battery even when apparently off.
if you see a fat link wire as pictured u need do nothing. if you dont see it there, look for 2 solder pads where the link wire is supposed to run, and solder a solid core wire between the 2 pads.
thats my green wire.
On some of these panels the current sink link is missing. on mine it was missing so i soldered a thick wire across the pads. without this you will not get a current reading. if the link is already there, great!
Well done on what must be a very rewarding project. You have brought the community together and turned around a rubbish tipping site into a desirable garden plot for all to enjoy!
