Horn Help Please!
The other day only the drivers horn was blowing. I order a new pass horn and install. It now blows but not the drivers unless I disconnect the pass then the drivers blows. With both horns disconnected and each side checked individually, each is getting juice. I've switched the horns from side to side and blah, blah, blah. Something else is causing both not to blow at the same time. A relay or whatever. I've got no idea. Anybody have any knowledge or experience on this kind of problem?....Frank

Re: Horn Help Please! (Frank C)
I'm looking at an '89 diagram, which may not be the same, but it sounds like these too much resistance somewhere between the hot side of the relay and the horns. (It says there are separate grounds for the two horns, so it's probably not a ground problem.) Do you have a meter? Watch you ears 
, but measure the volts between the hot side of a beeping horn and a good ground, like the block. This shouldn't be more than a couple of volts less than what you measure between the ground and the battery when the horn is beeping.

Re: Horn Help Please! (rmurcek)
Thanks for trying Robert. Yes, I have an analog meter. How could I measure the voltage at the horn without piercing the wire? Pretty sealed set up.I am/was really dumbfounded. Let me up date the situation. If I attached both A note's I get two horns blowing. The sound is a little strange but at least it's loud. I can't figure why the F (driver's side) was kinda working one day and not the next. I have a theory that when it is/was working it was sucking all the juice and preventing the original A (Pass) from tooting. Maybe that's the resistance your refering too. I'm sure that's dumb but I have know other idea as to what is going on. Maybe I'll try and change the pitch on the drivers side a note or just leave well enough alone......Frank

Re: Horn Help Please! (nobodyunknown)
I'm not following you nbuk. To your point, I've got a weather proof connector at each horn with two wires that only will fits one way. I believe it's a hot wire that goes through the horn. Push the horn and a relay trips allowing 12 volts to run through the horn circuit. The ground for each horn comes out of the harness about 6" before and goes directly to the frame. I assume yours isn't like that or I'm confused....Frank
