    Modify Ryobi Charger for Li Battery

    Ok... You can take a battery... Plug it into the charger... With no ac connected... And measure between the minus and the center pin... Should be approx 5 volts... Got to activate that battery logic... I also assume the charger is good... Sorry ., but I have to make all the assumptions

    You might also try taking one of those 10k resistors out... Make it 30k and not 40k....
