I have a LGB Forney and the LGB American Sound Tender. The tender has a cable that is supposed to hook to the locomotive. The Forney does not have a connector for this cable. Is there any way I can use the tender with the Forney and get sound? I would think this locomotive would have a connection for the tender but I haven't found it. ANy suggestions?

GW,

I'm suprised that the Forney does not have a "lighting connection" at the rear of the locomotive. The newer connections are square, and have a cover

on them that looks like a detail on the loco. Take a closer look at the back of the coal bunker. There should be a small rectangular shaped detail

with a small protrusion. If your loco has one, pull it out. Then look in the opening, and you will see two pins. The LGB lighting connectors plug

into this socket.

It has the lighting connection on the rear of the Forney. There is also a lighting conneection on the rear of the tender but on the front of the tender there is a socket for a flat 5 pin connector and i cannot find a connector like this on the rear of the Forney. I think that this must be present to get the tender to make sound.

It is not a case of just getting power to the tender from the forney.
The 69232 sound tender with the 5 pin connector has all 5 wires used.
2 wires are for track power to go to the tender rear connector for lighting passenger cars attached to te tender.
2 wires are for the 5 volt rear light on the tender which is direction sensitive
1 wire for the sound unit, the other sound wire is from the 2 wires to the rear connector.
reason for this......The switch inside the engine controls lights and sound per the loco manual and these wires are connected to the switch via the 5 pin cable on the 2-4-0 over sized seamer.
I wired up the 5 pin connector as follows and changed the bulb to a 24 volt version.
I wired 1,2,4 together, then 3 and 5 for the other wire. Tender light will be on all the time, but adding a diode to the light wiring inside the tender can polarize the light for direction.

Dan, thanks for that wiring diagragm. I am wondering couldn't I just make a adapter cable to connect the 5 pin to the lighting socket that is on the forney and make the necessary wiring changes inside the tender?

I hooked up the wiring temporary with the exception of the rear light and just tapped off the track to the tender. Everything sounded and worked great. As soon as I make up a cable to adapt to the forney light socket I should be good to go.

GW, I made a 5 pin to 2 pin adapter cable, added a diode for the tender light to be on backing up only, and changed the bulb to 24 volts.

If I use the tender on a 2-4-0 engine, the 5 pin cable will still work properly and all I have to do is change the bulb to 5 volts.
