Just purchased a Lionel Legacy SW8 Diesel Switcher- a Conrail #8657, Lionel #2133590, and after either programming forward and reverse operations, or manually performing forward and reverse operations the engine just sits there, and the cab lights blink on and off. I still have sound, and can here the rpm's go up or down while I turn the CAB2 wheel. If I power down and restart, all is well. I've tried TMCC and Legacy control. Other engines- ET44AC Diesels and a Legacy Cotton Belt Diesel operate just fine either programmed or manually, starting and stopping, forward and reverse.
I'm suspecting faulty board?? Ready to return. Any suggestions?
