Please correct me if I'm wrong. On my horn relay there are 3 connections, power coming in, a lead to the horn and the third lead to the horn button. The relay functions and the horn blows when the lead to the horn button is connected to ground. Is this right?
If this is correct then when I jump the terminal that goes to horn button directly to ground it should work if the relay is functioning correctly and of course the other connections are in the right spot. Is this correct? Does this make sense? | | | | | Joined: Jul 2004 Posts: 5,708 'Bolter | | 'Bolter Joined: Jul 2004 Posts: 5,708 | Mike,
It's correct and it makes sense. If you have any question about your horn or relay, ground that horn button terminal and tap on the horn and relay with a screwdriver handle...sometimes you need to wake them up.
If the relay is working, grounding that horn button terminal should make a click that you should be able to feel with your hand in the relay.

I guess I need a new relay. | | | | | Joined: Jun 2003 Posts: 565 'Bolter | | 'Bolter Joined: Jun 2003 Posts: 565 | Make sure you have power to the relay and make sure the horn is grounded well.

Napa has 'em for about $10. | | | | | Joined: Aug 2005 Posts: 424 Shop Shark | | Shop Shark Joined: Aug 2005 Posts: 424 | Well, it was a bad relay. I replaced it and that did the trick (Napa $18). I also took off the custom steering wheel that the PO had installed and put on an original and replaced the little italian sports car horn that was on it and installed an original horn. Now it works. All those years of scrounging extra parts sure pays off.
Thanks for all your help. | | | | | Joined: Apr 2009 Posts: 10 New Guy | | New Guy Joined: Apr 2009 Posts: 10 | Old Gold! Someone paid a lot of money for that custom steering wheel and you just go and change it. Sheesh! You're a lot like me, I guess. I like the old trucks because they were/are a lot of fun (challenge?) to drive. I like mine mostly original, too. WHen I see someone has added those little bitty steering wheels, or bucket seats, Auto transmission, etc, I almost want to cry. But to each his own, and I understand some people want added safety/comfort of disc brakes, power brakes, power steering, etc.
But where's the fun in safety? :-)
