k line reverse board repair

Victor BertolinaOGR Forum Member SUPPORTING MEMBER

Can a failed e unit from a k line S-2 be diagnosed? I did replace the failed board and the loco runs fine now but I am interested in repairing the original board. The board heats up rapidly and does not seem to have any output voltage. My only diagnostic equipment is a multimeter. There were no signs of physical damage or overheating to the board components.
