Gunrunner John's YLB (Your Last Battery) #10510 with the sound board plug fixed the sound drop-out problem with my Atlas O O-72 and #5 switches. The battery quickly charges and provides enough power to the sound system to ride over interrupted center rails.
Below are pictures of the simple process of installing the YLB 10510 Battery. Power for the YLB comes from the screw for the center pick-up roller. No soldier needed, but tighten screw,
Please note that the bundle of wires inside the tender are so tightly bundled with little slack that my tender arrived with the power plug loose and out of its board socket. I had to pull extra gray wire from the bundle to re-connect the plug.
The video shows the sound drop out over an O-72 switch.
My engine still needs service because the Engineer's side rear drivers Ground Light LED does not light. It's always something.
Sincerely, John Rowlen
