Burned ground wires usually mean a loose or corroded connection heating up, so replace or clean those terminals no matter what. For the N641 boards, the serial number decides. Below 9044284, it's the 633287 kit. Above, it's the 628976 optical board plus the 628661 power board. Please send us your serial number.
