Fixed command antenna wire

What is the engine? Can you take a broader view picture of the engine so that one can see what the wires come from or maybe go to?

It's 6-11131 FEF3 UP 844. Here are more pics. Let me know if they aren't sufficient

Where does that double wire go toward the left? Usually the antenna wire secures to the two hand rails that pass thru the shell insulated and come together to a single connection that plugs into the mother board. The radio board is in plain sight on the right, upside down plugged into the motherboard. There is a single wire plugged in the motherboard to the right of it. Where does that black wire go? If that double wire has the two wires going to the handrails, then the end you are lifting up with the pencil goes to the mother board somewhere. The upside down radio board is where it eventually goes...thru the mother board traces.

Yes, you're right the wire I'm holding is two wires which go to the cab then hook up to both the antenna wires outside the shell. I'll look for the radio board connection.  To be sure for me, the radio board is on the smoke unit side upside down. So broken connection should be visible there. Correct?

The broken connection should be on the end of a white or black connector plug...or on the end of a wire that goes nowhere now. Did you look at that black wire on a white plug, plugged into the mother board. It's just on the top right of the upside down radio board. A black wire comes off it and goes to the left under a bundle of wire. Look for where that single wire goes. 

The radio board plugs into the mother board, and the mother board has pins that carry radio board connections to the outside...like the antenna wire.

Oh. I see another black wire below the one with the white plug. It plugs into a single pin and has a black small square plug on it. That single wire also goes off to the left...look for the end of it. I think that is it.

Maybe not...hard to tell from the picture. Does this second black wire plug in with that red wire...or does it go just to the right of the red wire in the white plug?

You might have found it. Does this look right?  Problem is I can't replace. Need new plug.  Actually, just a tiny connection for the wires into the plug. 

That plug may have only had one wire in it. The one wire...where does it go?!

I see now that the plug below it has two wires in it...and that black thing I thought might be a plug is a diode or something.

But what is on the other end of the black wire coming out of the plug you are pointing to?

Back to the larger plug connection that mates shell n body. 

Is there a broken connection on the body end of that big plug? Is there anything coming out of the body side plug in that location on the plug? Could the double wire be connected to our single wire thru the big connector?

So one more possibility on the shell side an open place and matches that single black wire we showed previously on the plug. 

That looks like it. Take a good look at the end of the double wire and see if that metal clip is actually a connector pin that goes into the white big plug. Does it have a barb on one side? If so, can the barb be carefully bent out a little so that when put back in the connector, it will stay? Look at how the other pins are inserted and see if you can orient the double wire metal pin as they are and reinsert it.

The barb is toast. I am now robbing Peter to pay Paul on another plug I happened to have. Back in a minute after trying this.  But I am hopeful you are right, it's the right one

No joy,  I think the little metal connector that slides into the white plug is the wrong size. Was a crapshoot anyway. It didn't seem to snap into place properly. Couldnt get it to seat like it should. But I really think that's the proper place for the wires. Oh well. Thanks so much for the help identifying the problem, Chuck. Just need th right part. What do I ask for?  Has that plug got a name?  Ted

I'm not a 100 percent of which plug series that is. Gunrunnerjohn on the forum and others could tell you for sure and also give you part numbers for the proper pin to connect to the double wire and then reinsert it. Maybe what is left on the double wire is just the crimped part and the part that encircles the pin on the body side of the connector is still in there...or fell out somewhere.

You could also wire around the connector, but getting the right pin would be my choice. Many are at the York train meet right now, so they may not respond quickly, but send John an email and ask him.

It can wait. I have a train to run. He's probably having too much fun at York. Next week sometime. Thx again for the assist. TW 

Guess I couldn't wait. Went ahead and bypassed mating shell/chassis plug and command works fine. Now, just remember there are two plugs to unhook when removing shell.   Thx again for the help Chuck. TW 

Sounds like a plan. I was temped to say the larger JST connector and pins, but couldn't be sure. Two things to connect is typical...usually the double wire is made into one wire and plugs in where it is on the mother board. BTW, I think you mis-identified the upside down radio board as over the smoke unit. It's not. It's the board to the left of the smoke unit. The board on the smoke unit is the smoke unit itself. But all is well now anyway.
