Hi Guys, I'm new to the forum and am looking for an answer to why my LGB 2-6-0s chuff stopped working correctly. It just has a constant hissing sound now instead of the nice factory chuff it used to have. With the battery removed from the tender a faint chuff sound can be heard but very faint and only had at about half throttle. After removing the top of the tender and examining the board I did come across a melted red wire that runs down to the front truck. I did splice in a new section of wire. No change in the chuff sound. Any ideas would be greatly appreciated. Thanks, Rob near Chicago
 
A photo would help, perhaps?

Could you give the LGB model number?
Analogue, or digital?
If digital, do you know the make of decoder fitted?

Though I fear it may turn-out to be more than just a wire that has been 'fried'..

Hello, the model number 2119S. Thank you for your quick response , Rob
 
The problem is highly likely to be the plug connection between the loco and the tender.
The wires do tend to break off.
Once you fix it, smear a bead of silicone adhesive along where the wire go in the plug. That will stop the wires flexing at the point of entry into the plug.

Tony, thanks for your quick response. How can I tell if the wires are broke and the problem? And how do you replace all of them? Are replacement harness’ available?190"]The problem is highly likely to be the plug connection between the loco and the tender.

The wires are a press fit inside the plug. That is the plug itself cuts into the plastic wire cover to make contact.
You will have to carefully remove the wire cover on the plug and test each wire to see if it is good. Remove old wire residue with a sharp knife.

Fixing is more problematic. How I do it is to shorten the offending wire about 20mm, splice a new bit of wire to the now shorter original wire and press the new bit of wire into the plug. Easy for me as I have a tool that does things like that. You would likely have to carefully press the wire in with a small screwdriver.
Good luck.

In the other thread at LSC I think Dan Pierce said replacement cables with plugs are available from Train Li.
That would require soldering the cable to the pcb inside the loco.
