I have a N Scale Bachmann RS-3 with DCC. (Boston and Maine 1505). When placed on track it lights up but will not move. Lights actually change direction but no movement, not even a motor hum. I've change CV-8 to 8, no result, changed CV-8 to 33, no result. After each attempt to change CV-8 when reading it is always 101. Is there any way to revive my loco.
