I have tried everything I know to get the cab lights to come on in an Acela engine. It is in the TMCC control system. Without a diagram of the Motherboard, Radio, DRDU, RS power, or RS Boards it is hard to find out which control board controls the cab lights. They are to turn on when the engine standing still, and turn off when the engine moves.
Maybe someone on this forum has this information from the past.
Thanks in advance for your help.
