I may have spoken too soon. I just ran the engine for about 2 minutes with my hand on the DCDS heat sink and barely noticed any temperature change. Before I brought this engine in for repairs, the heat sink would get so hot after only about 30 seconds that I physically could not touch it. It's also not shorting my lionel CW-80 anymore. I'll run it for a little bit longer before I reassemble it just to make sure it won't break down again.
