Mower Won't Start or Turn Over?

I have a Briggs and Stratton mower and it won't start. I tried hooking up jumper cables and turning the starter over that way, but the starter won't turn over. I tried taping it, also tried a new starter, still nothing. When I turn the key I can hear a clicking coming from a little black module under the plate below the seat where the pos cable connects and another red cable that runs to the starter, it also has a small orange wire. I replaced that too and the spare one does the same thing. The fuse is also fine. I'm lost; please help!
