I am planning to fit a sterling regulator but am having touble trying to even find out what the rating of my alternantor is. It is fitted to a 20 year old Bukh 10, but i have no idea if it is the original alternator or not. It has a stciker on it saying Delco remy and an engraving that reads 621 5X39 2 70A LY. Does this mean anything to anyone as I cant find much to help on the web
