I have a Lionel 6-27082 J3a Hudson that has all burnt wires in the tender. I cannot find a wiring diagram either on the Lionel web site or in the supplements. Does anyone have a diagram for the tender? I have to make all new harnesses and the wires are so burnt I can't make out what wire goes where.

Thanks,

Ed

When I had burnt wiring in the Genset, I saw that no harnesses were listed in the parts fiche for that model. I then found harnesses that I could make up what I needed (number of wires and appropriate connectors) by searching thru hundreds of harnesses I found with the search term "Harness" in the search for Replacement Part Number or Name.

There were two different connector sizes (in addition to number of wires). They were listed in Digikey as 2mm JST PH series and 2.5mm JST EH series. And the pins are different...labeled P0.5 and then P0.6 for the bigger connector. The pictures of the harnesses were difficult to see which connector series is used, but the 2.5 mm have a ridge on the sides and the 2 mm are smooth sides. This worked for me to tell. Although I have the connectors to crimp on, it was worth a few dollars to me to just pull the appropriate sized already crimped on wire with pins and insert them into the appropriate number of wire plug. Kind of a challenge.

It's possible your tender pickups got across two different blocks and the power wire melted the other wires? That would be less likely to have hurt the boards.

Sorry guys I did get the numbers reversed..........it is the 28072 and the wires are so burnt and stuck together I cannot identify what wire goes to where. Thanks for all the suggestions and I will look at each one suggested including the part numbers from Chuck. For Gunnrunnerjohn I too have that wiring diagram and that is the one I will use once I get the harness built. I was able to find several of the different connectors on the Lionel site and between them and Digikey I think I will have what I need........thanks again for all the suggestions.

The 2.5mm connectors are the JST-EH series, and the 2mm connectors are the JST-PH series connectors.  Note that in spite of the fact the pins look similar, they are NOT compatible, you need the correct pins for each series of connectors, they appear at the bottom of the page for each connector shell.  I use the Engineer PA-09 Crimp Tool to crimp these.
