Looking for any ideas with my BLI ES44AC. It’s always been a little sluggish, but now won’t move. It is making sounds, lights, horn, bell all work and the engine sound accelerates when the throttle is advanced, but no movement. Operating in DCC mode with an NCE Cab. Tried resetting CV8 to 8 but no change to the results. Thought I’d try here before sending back to BLI. It’s a year and a half old, so age isn’t an issue. Of course it’s over warranty. Thanks in advance for any help!
