I have been pulling locomotives out of storage that have not been run in years. I have had a couple of issues now related to electronics. Most recently, I took out my Lionel U.P. SD-40 Tunnel Motor (from around 2002-2004?), lubed it and ran it under TMCC. At first the smoke unit did not seem to work, then it started working, then-very suddenly-it started working too well. Clouds of smoke came pouring out of it (accompanied by a interesting electrical smell). Before I could get it shut off, the heat had melted the small rectangular grill (smoke outlet) on the top of the locomotive. The locomotive was running at between 16 and 17 volts when this happened.
None of this seemed to interfere with its running or sound capabilities.
Has anyone else run into this?
Is it possible to purchase the smoke outlet grill?
I am not upset with Lionel, by the way, at the engine is between 14 and 16 years old.
