Shorting issues with DCC Heavy Mountain

[kalinefan]

Anybody out there have any ideas as to why my Spectrum DCC Heavy Mountain is frequently shorting?

Are you running it DC or DCC?
The first one that I received had a decoder short out, which was evident by the loco's hesitance to run and the tender decking melting.
I sent it back to Bachmann, and they quickly sent me another. I had to re-number/re-letter for B&O, but the service was quick and easy.

If the problem is constant and only that loco, it's probably just a lemon. Send it back.
