I have been working to bring back to live a K-line Mikado.  I have everything working and rewired; however, the locomotive started to stall in tighter turns.  I appears that I have a bad connection in the 6 pin tether plug between the tender and the locomotive.  Inspection shows that some of the wires are crimped and the center roller (hot) wire is missing insulation at the plug. Slight adjustment to the wires brings the locomotive back to life.

Does anyone have a specification or part No. for the 6 pin (3 over 3) K-line tether?  I don't mind making up my own assembly but am not sure which plug will match the original.  Alternatively, If anyone has any spare 6 pin tethers that they would like to sell, please let me know.  I need a minimum of 4 positions, 2 motor leads, one common and one center rail.

So I was able to dissemble the tether plug.  I could not find a replacement plug; however, Hirose makes a similar plug with an identical female plug.  I purchased a few of the DF11, 2mm pitch female plugs and rebuilt the original tether.  the insulation is very soft and some of the leads required more than one try with the crimping.  I figured that I would share my fix since the tethers are hard to find especially in the 6 pin, 6 wire format.

Hi @Christopher or @gunrunnerjohn!

Can you share the link to where you purchased your connectors and the crimp-on ends? (and tool) Please?

Thanks,

Hello guys

I need to aquire that connector and pins.  I don’t know if I need the male connector on engine yet.  It is a moot point if I can’t rebuild the tether.  The wires were burned as was some of plastic in connector housing.  I think that is still usable.  I have not been able to extract two of the six pins from connector, so I need both pins female and connector for tether. If male pins and another connector for engine are available I would buy both.  If someone has those to sell I would be grateful. Gwerderich@aol.com

If you need the board and socket on the locomotive your best bet is brasseur’s electric trains. I bought one from them. Unless you want to get into making your own board or trying to replace the socket housing.  It would be a little involed with six points on the board. Brasseurs may still have some 6 wire tethers too but when I was looking, they didn’t have one with the wire positions I needed but you can just buy the df11 sockets listed above and modify.  

If your locomotive plug is good or you can find a replacement but can’t find a tether, let me know. I can check to see if I have any extras.

Looks like no one has the correct Hirose connector but these should fit and easy to solder wires too, no crimp tool needed. You just have to be careful when you plug it in the orientation is correct as the key is different.
