I think I found the problem by accident. I had one of the new horns hooked up with jumper wires to the battery and all I could get when I made contact with one of the wires was that bump sound again. I was already aggravated but then I just got plain ol' pissed off, called it a bad name and smacked it with a hammer and it started blowing. I unhook the wire (alligator clips), it stops blowing, then when I reconnect the wire I get the bump sound once more, I smack it again and it starts blowing. Hooked up the other new horn the same way and that horn does the same thing. So, both horns blow just fine and loud but I have to smack both of them to make them work. I hooked up an old horn from my Dodge van to the horn wire and grounded it and when I press the steering wheel the horn blows with each press of the steering wheel. So, the clock spring and everything is good to go, my old horns are no good any more and the new horns are apparently junk. I'm going to play with the new ones a little more to see if I can get them to work correctly, if not I'll have to get two more new ones.
