I recently bought a used K-Line S-2 dual engine switcher. It would stop each time it crossed a switch. Thinking that one of the pickups was not working correctly, I opened it up and noticed that several wires were "fried" I mean, melted. The insulation cracked and fell off of the wires coming from the pickups. Enough of them were so that I can not figure out which wire is which. It also has a solid-state board in there. I have only worked on Lionel Post-war engines before, so this scares me a bit.
Does anyone have a schematic, or can point me in the right direction? Google searches have not turned up anything. The Santa Fe engine is #2313 and the number on the underside of the chassis is "K-Line K-2200-8".
Thanks for any help!
