HI Guys

I went to a train show today and picked up an older whistle control button 8251-50 .I tried it on a test track with a small lionel 25watt trans. It worked fine but when I tried to hook it up to my layout powered by 250zw trans. it popped the circuit braker to that track. I can’t find a wiring diagram for wiring of this control button to make it operate properly with the zw tranformer.I run a conventional 3 loop system, nothing fancy. Can anyone help with a wiring diagram? thank you MODEL A

Thats the one in red plastic, they are not reliable and prone to burn out. The diodes don’t seem to handle a heavy load. I can’t say for sure but the power of a ZW may have fried it. Try it on the other transformer again.
