i tried to put common the pin 3, on GND, then 12V, then GND again.... i tried directly to put 12V or GND, when inversed, with a wire directly to the contacts, not a peep? what am i doing wrong?
i thought that electrically speaking i go 12V to the houe bell switch, back to the input entry, and put the 12V- GND on common? but that simply doesn't do it?

you can take a photo how you wire?
i don't understand which pin on PCB are you are using.
