You have an impedance in the AC supply common to the thing causing the
click and the thing receiving the click. That's the simplest way to
put it. It might be the wires, the ground, the transformer, terminal
blocks, fuses, or anything else. Go further upstream with your click
inducer and click receiver and see where they stop. If you've hooked
it all up to the pole pig and it still happens, that's your culprit.

Cheers,
D.
