These tractors charged with a 12 volt alternator because the alternator or generator has two separate 12 volt terminals. One for each battery. The battery's are isolated from each other so then it works. The battery's are connected in series for starting. I don't understand how it all works

JD had no 24 volt system charged with a 12 volt alternator as you describe. Maybe some other company but not JOHN DEERE!!!!! There is a 12 volt alt listed in 5020 parts catalog # 978 sn< -024,999 but this is how the footnote reads (A) 24-VOLT TO 12-VOLT START/CHARGE CONVERSION KIT
