I tried to search this out but I may not have the lingo correct. I have a 47 Ford with the origional flathead and ignition system. I was told that if the battery is disconnected for any lenth of time that the generator looses it memory of how to charge. This is when I need to 'flash' the system. I don't have a clue what I need to do. Could someone please let me know the proper proceedure for this. Me and electricity are not friends... Thanks!
