Hello
I have MTH SantaFe Dash 8 diesel with malfunctioning DCRU (upper) sound board.
All it does is blowing HORN constantly and is unresponsive for pushed buttons, train speed or direction...etc
I removed this bard from locomotive and looking to identify responsible element(s).
In worst case of scenario I will check PCB traces and elements one by one, but before I"ll start
can you share please any suggestions or schematics (if available)?
I appreciate your help
