[QUOTE="pow, post: 390188, member: 18476"] Hi, I'm normally fairly good with automotive electrics but I'm stumped on the horn in my early bay. The horn has two wires going to it, looking at the wiring digram one comes from +12v and one goes to the wire that pokes out the middle of my steering wheel (that should have the horn push attached to it). So, logic tells me that to complete the circuit (Beep beep) the horn push (when connected to said wire and pushed down) completes the circuit by earthing the brown wire. But, what I don't understand is when I do a continuity test on that brown wire poking out the steering wheel to earth (some metal inside the steering wheel for example, or anything unpainted on the van) I get continuity - the brown wire and the vans earth are constantly connected? Is that right? I don't get it if it is the case! Can someone explain this to me please? Thanks :) [/QUOTE]
