To drain the GCIO, just use your meter...not the screwdriver...or 10 cents coin...go on dc voltage on your meter...keep your meter lids crossed and touch the legs of supercap for 5 minutes...after 5 minutes you need to measure bellow 0.5vdc...if you're bellow 0.5vdc you're fine...connect it back to the CRIP board.Good luck!
