This has been going on for awhile now and I search this forum for clues. I have a Legacy 10 wheeler 6-82267. One day it just quit after 3 + years of working as designed. I was using a zw-c (old chip) with 3 135 w bricks. One for each track.
What it does. Sometimes when I power the track it comes up in idle only sound, no Legacy control at all. No conventional control at all. If it comes up silent and no idle, just a quiet buzz, I have speed control through the cab 2. No acknowledgement to the cab 2 like sounds or whistle. When I try to re-program it to its number, 13, there is no horn after set. It does not respond to #1 or #99. If I have the tender only, it comes to idle sound consistently. The loco does come on with the front light, marker lights and firebox flicker. AND the cab light flashes two times continuously.
What I have done. Last month I ordered a new board. I installed it and there is no change. I have re-plugged all the plugs in both the loco and tender. I have checked continuity between the un-plugged antenna wire and the rails. Good. I have checked the continuity of the unplugged wire to the drawbar IR (loco side). Good. I checked continuity with the pickup rollers and the power side of the plug. Good. Same for the tender. I’m not sure on the IR for the tender side as I did not get good connection there. Could be my bulky tester probes. I checked the continuity on the program/run switch and reset the wires anyway. Good.
I need some guidance for further investigation. And I’m not against sending it in to someone. Lionel is only doing warranty work.
