Good Morning/afternoon,

I need to know if anyone has a Weaver RS-3 locomotive that would be willing to take close-up pictures of the wiring so I can finish my custom build?  Does anyone know where to find the wiring diagrams for these older Weaver models?  I know Atlas bought the Weaver tooling, but not sure if anything else was retained and archived for reference elsewhere.  I started this project over two years ago and due to my job, a move from OKC to Huntsville, and then open heart surgery I had to put it on hold.  Well, now it is the time to get it finished.  Any help would be greatly appreciated.  Attached are some pictures of my project.  I wanted to retain the ConRail RS-3 shell, So I got another shell to replace it.  I had to replace the top gear on the drive tower as it had a micro split in it and kept binding.  Other than that, as long as I don't blow-up or burn up the electronics putting it back together it will work great.  Got it painted in the Detroit and Mackinac colors that it had when I was stationed at Wurtsmith AFB, MI.  This locomotive along with an Alco S-2 would move 15 to 20 tank cars onto the base full of jet fuel to be offloaded at bulk storage to support refueling of our B-52 bombers and KC-135 tanker aircraft.   I'm adding the custom detail parts I gained from P&D Hobby.

BBM,

I doubt you will find a wiring diagram for the early Weaver RS-3s. That said, the wiring on these is pretty straight forward, as long as you stay conventional.

Please post a well focused picture of the reverse board. We will be particularly interested in any markings associated with any wires on the board. That will be a huge help for us to tell you what you need to know.

Is the motor still connected to the board? If so, that's a plus. I will presume the trucks are identical. For each truck, there is one wire that connects to the center pickup. These are referred to as the "hot" leads. They  get tied together and connected to the appropriate (yet to be determined) spot or wire on the board. There will be at least on more wire, maybe 2, that come from each truck. These should go to the copper wipers on the inside wheel surfaces. Tie all of these from both trucks together. These are the Common or ground leads. They will be connected to the remaining spot or wire (yet to be determined) on the board. I see no indication of lights or a sound system, so this is about as simple as it gets.
