Hi, not sure if i am doing this right - first time on here but here goes.  Upacked my train from some 50 years ago and am setting it up for my grand kids.  Found a Marx No. 418 Bell Ringing Crossing Signal but the internal wires are removed.  How can I locate a diagram showing how the internal wires should be connected to go to the track?    Any help is appreciated and if i posted this to the wrong area please let me know.

Thank and be safe out there.

I don’t have a diagram, but found one I have downstairs. There should be one wire coming out of the bottom. That is wound around the binding post under the base that has the insulating spacer between the base and post.788B406F-559E-4822-BC28-DC01AB6B9B77CB070E64-5C5A-4C3B-BF86-FA9FEAC0E532The other post is the ground circuit through the base. Hope this helps.

Use of the frame for "common"(chassis as ground or hot) is commonly used; not just in Marx. Your average locos and cars use it too    (ac terms about ground aren't used exactly as dc might be, "common" is usually more correct as hot vs return changes 60 times a second; but context varies fyi.   

 

Here's a view of another Marx 418 that I repaired some time back which might make the wiring clearer: 

GEDC1963

What kind of track are you using?  I've had success in cutting gaps in Fastrack, running a wire to the gapped section and using tha to actuate the bell.
