Bart,
I'm back. Please dumb this all down; way down for me. I get it that the wire coming out of the column is a "ground". What I cannot wrap my head around is...
what "powers up' the column and where?
I understand that the horn button is a switch which closes the circuit when you press the horn button and the horn beeps; but where does the power come from?
Thanks in advance pal.
Ed
