plymouthcranbrook Posted September 27, 2015 Report Share Posted September 27, 2015 (edited) I've managed to get my self into. I know some of you have seen my thread on my turn signal problem and many of you have offered suggestions. You might have seen a comment I made about the horn on my 52 Plymouth being another thing that didn't work. Well, today idle hands being the Devils Playground, I decided to take a look and see what if anything I might be able to do with the horn. Now I want to say that automotive electrics is my weakest area of repair skills. Still I decided to see what I could do. I was able to check and see that both horns worked when 6 volts were put directly to them. Loud and long. They I looked at the schematic in the book and traced the wires from the horn relay to the horns themselves. Then I tried putting 6 volts directly to the horn on the connection on the relay. The horns blew. Great I thought. Perhaps I can rig up a temporary horn button and use that till I take the steering wheel off to check the aforementioned turn signals. I decided to use the radio power source as the radio didn't work anyway. I removed the wire from the horn button(lower right on the relay if I read the diagram right) and proceeded to run a wire to the new horn button and connected it to the radio feed through an inline fuse. Before mounting the button i decided to check operation. Nothing. I checked volts to the horn button, 6 volts. Then with the button pressed checked from either side across the button. 6 volts. Then from the feed side of the button to the relay with the button pressed. 6 volts. Checked continuity from one end to the other. Good continuity. Put 6 volts to the relay again. Blat, horns work. push button, nothing. I did notice while checking that one of the terminals(center one) is hot all the time. Anyone have any idea what I have missed? Should I have just got a 3 or 4 wire 6 volt relay and just used that? I am confused. I also asked my neighbor who has had his own home based repair shop for years and also his brother who was a maintenance man before he retired and they both seem to think my plan would work. Thanks if you can help. Edited September 27, 2015 by plymouthcranbrook Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted September 27, 2015 Report Share Posted September 27, 2015 What would be really nice is to not start a new thread for problems already discussed in other threads you have started. Best to keep all the eggs and answers in one basket. You might ask a moderator to combine the threads. On your horn issue the horn relay is "hot" all the time. The horn ring under the steering wheel grounds the circuit and allows the horn to toot. Try running your remote horn button to ground, not to a power circuit. 1 Quote Link to comment Share on other sites More sharing options...
plymouthcranbrook Posted September 28, 2015 Author Report Share Posted September 28, 2015 Please accept my apologies for incorrectly starting the new thread. I had only mentioned in passing about the horn and thus thought(incorrectly) that a new thread was in order. Thank you for input Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted September 28, 2015 Report Share Posted September 28, 2015 I believe you did fine by starting a new thread for your horn issue. As you say, it is a different issue. If you were doing a "work in progress" thread to cover all issues that you are working through, then it would make sense to put it all together. But in my opinion what you did is perfectly fine. Other than that I believe Don makes a good point. It sounds like you connected your horn button to the horn activation terminal of the relay. That would be correct, but it needs to ground the relay, not power it up. Disconnect your power wire from the switch and reconnect it to a good ground and try it again. You could even test it with a jumper wire between the relay terminal and a ground point. Merle Quote Link to comment Share on other sites More sharing options...
pyrodork Posted April 13, 2016 Report Share Posted April 13, 2016 On the subject of horn wiring, I recently bought a 48 Dodge with the horn button removed and the horn was wired to a remote button (works). I think I have all the internals (a Y bracket, spring, and button contact, no wire) and bought a new button on eBay. Want to know how to put it together and have it wired properly. Also found a cut wire coming off of (I think it is) the horn relay... Bottom terminal, radiator side. Is this the connection for the wire through the column?

rb1949 Posted April 13, 2016 Report Share Posted April 13, 2016 Was there ever a solution to this? And Pyrodork new questions. I fought my horn for weeks. Maybe the discussion, and photos, will help. http://p15-d24.com/topic/40502-49-chrys-horn-horn-ring/ There is one wire going up the column 6v, which you need to install. Check that cut wire to see if its 6v. Grounding it may toot the horn. (with key on). If good, run the wire topside. Only 3 pieces up there. The spring keeps the horn button from making contact. Pressing the button makes the connection to the Y thing which is ground, and the horn should honk. Good luck. Those old horns sound great. 1 Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted April 13, 2016 Report Share Posted April 13, 2016 the wire going up the column from the relay is ground, not supply Quote Link to comment Share on other sites More sharing options...
BigDaddyO Posted April 13, 2016 Report Share Posted April 13, 2016 I told the waitress that my coffee tasted like mud. She said; "It should, it was ground this morning". 1 Quote Link to comment Share on other sites More sharing options...
