I’m looking at a Phoenix sound card installed in a Bachmann 38 ton shay and I need to identify the model so I can get a wire diagram to trace the wires. Something isn’t sounding right and the volume switch isn’t working. The only markings I can see reads G-3826. looking that up didn’t get me too far.
I also need to figure out the battery situation for this. Online directions said to run it a few laps at 8 volts to charge but that did nothing for it. I suspect the little yellow 3 cell pack is the original and might need ot be replaced.
Any ideas?
