A got myself a very cool AYK charger. It was the high tech thing in the late 80's. I know it can peak charge, timer charge, discharge, test motors, etc etc. The only thing is that it has a whole bunch of swiches on the front panel and you get the different functions by setting the swiches in a particular combination. I have no instructions for it but it has the the attached diagram at the back. I'd like to know what are those switch set-ups for. Its in japanese so If you can help please let me know what it says!
