Working on a gray 785 Hudson. The three wire connectors to the SOS/whistle were removed/lost and the new owner of the engine would like them replaced.
I have three wires coming out of the circuit board in the tender (brown, black, blue) and nothing from the back of the engine/brushplate.
I have a pair of spare connectors with wires attached. I just need to know which gets soldered to where on the engine brushplate.
Thanks in advance,
John
