I'm looking for wiring information for a 38ton 2 truck Shay. Is there a wiring diagram or has anyone traced the wires? The majority of the wires are black and I need to find out where the come from. I'm installing a Zimo sound decoder and smoke generator and have removed the the old non sound decoder and the available schematic is of no help.
Thanks for any help,
Al

No, I have those diagrams but since this Shay had a decoder in it that PC board was no longer in it. The schematic gives wire colors but the wires are all black so they have to be traced. Since I asked the question I have been able to find the wires from the chuff contacts and the black wires from the fire box PC board. The only wires I need to find are the ones going to the cab light.
Thanks for your suggestion it is appreciated,
