Hello,
Hopefully somone may have an answer for a problem that I encountered. Friend of mine purchased a used MTH PS-2, 2-10-0 Consoladation and no sounds or smoke. Removing the shell from the tender their I saw 4 wires that are broken from their solder connections. I have attached photo's that show the wire colors of pink, blue, gray, and red. There is a blue jumper that goes from the pot to the other. Thank you for any assistnace, Mike
