Stephen, where did you get your ZW worked on? I bought mine at York (this year). The fellow I got it from is well known for transformers. When I got it home, I discovered it was wired backwards for the whistle. When I push the whistle, the bell rings. I haven't changed any of the wiring on my layout from using my KW and CW which is how we (other club members) came to that conclusion. Also I need a diode put in mine too. I have a friend who is a Lionel tech who can do it, but I like options.
