Dan Padova posted:I hooked up the whistle/bell switch, between my post-war ZW and the track, following the instructions. Unfortunately the bell will not sound. If I slide the switch to the bell position and turn the track power on, the circuit breaker I installed between the transformer and track trips instantly.
Dan,
If you're trying to use the slide switch that came with the B6 to operate the sound, in a word... don't.
Those 5904 boxes were only used on the first two RailSounds locos (the B6 and Reading T1) and created more problems than they solved.
RailSounds 1 boards will respond to the bell button on your transformer, or any of the 5906 Sound Activation Buttons which were the successor to the 5904.
