Finally got my hands on a Green GG1 with a realistic sounding horn.
I'm researching replacement batteries and/or a BCR for it. The box is labeled Proto-Sound 2.0 as seen in photo. The battery is currently showing a full charge. When I search for replacement batteries, *battery chargers* are among the hits. Surely the battery charges in the engine - right? I'm attaching pics of the chassis & box.
Since the engine runs, horn and bell sound, I assume that it is indeed a 3volt PS2 board.
Can I get the freight yard sound effects running conventional with my ZW?
My Lionel GG1 (6-38520) certainly, has more pulling power than this MTH.
So.... is J&W the only place to pick up a reasonably priced BCR? I see that GunnRunner John had posted home made instructions somewhere, but I can't seem to locate that thread.
The engine is also missing two tires.
