Lionel 6-82396 UP Auxiliary Tender Coupler Getting Very HOT? | O Gauge Railroading On Line Forum

Hello,

I purchased this used last year to run with my MTH Big Boy, which still hasn't arrived. I ended up running it today with another steam engine and after it sat on the powered track for a few minutes, I went to couple it up with another aux tender and the coupler was very hot. Almost burned my finger. Looks like it was melting the shielding tap as well. FYI, I don't have Legacy. I'm running with an MTH DCS Explorer and 75w power supply.

I'm guessing there's a short somewhere. Any idea where it might be?

Thanks for the help,

Cyril

Without visual inspection of the wiring, it's hard to say. However, if the wiring all looks good, my guess is the coupler triac on the Legacy receiver board has shorted. The coupler shouldn't be doing anything without being asked.

Here are some close ups of the board and wiring. Does anything look odd?
