Horn problems
My 1983 F150 is wired like the second vehicle you mentioned. However, my 3 prong horn relay has only (1) wire connected, this seems wrong to me. Shouldn't it have at least (2) wires, one "in" and one "out", otherwise how does the relay get enerized? I have power at the steering wheel, and the horn(s) work with a "hot wire" from the battery to the horn(s). When I press on the rubber horn plate at the steering wheel, I hear a "thud" which I assume is the relay, but the horn(s) wont blow from here. So, is it the lack of the proper number of wires hooked to the horn relay, a short, or a bad ground of something, or a bad secondary horn (which sounds muted compared to the primary horn to me) or something in the column?
(p.s. Subsequent investigation has resulted in finding that the secondary horn will not work on or off the vehicle, leading me to believe that it is drawing too many amps rendering both horns ineffective. Attempts to adjust the horn was unsuccessful via the screw on the back of th horn. Therefore I removed the secondary horn and the primary horn is working. I only hope that electrically, this will continue to work and not become a problem.)
