I recently bought this loco 2nd hand. The loco runs, the blinking Led works and the light bulbs, but it has a horn sound and it doesn't work.
Would anyone know how it supposed to work ?
I suspect one the components on the "Space Age Electronics" on the PCB maybe faulty.
I connected 5VDC to horn and it makes a sound, just not while it's on track.
Would anyone have circuit diagram for part no.3102 ?
