John Cullen, My Greyhound Challenger powers down and the sound goes off even though the track power is still on. I can also shut my transformer off with the engine sound on and the sound shut down in about 5 or 6 seconds with appropriate shut down sounds. This is probably what the battery would do in conventional transformer operation.
Gunrunner John can give you more information. This is how the new Challenger acted with the YLB 10510 battery in the tender.
You mentioned that you lost power to the tender. I found the power plug was out of the sound board socket because the wires were bundled and pulled on the power plug/socket connection. I pulled a little more slack from the bundle and plugged the cable back into the socket. It works fine now. The tender lights also stay on going over Atlas O switches.
Sincerely, John Rowlen
