CNP934DC Posted September 18, 2009 Report Posted September 18, 2009 After a year of messing with my horn and getting a lot of tips from this forum, I finally got the horn on my P-15 working. Some of the tests I did way back (as suggested here), included running a test wire from the horns directly to the battery and various other tests to test the relay. All the tests worked but when I hooked up all the wires....nothing! Last week I installed a new horn button wire that I found on e-bay and re-checked all the connections and ground. My neighbor came over (a real car guy) and asked if I tried adjusting the horns themselves. I said no, because all my tests worked fine. But he suggested that the power would be greater going straight to the battery than they would going through the relay.Sooooo, I took the horn covers off and while I pressed the horn ring he turned the adjusting screw in each of the horns and bingo!! :)Horns are working. If anybody out there has experienced the same problem I had, make sure you check the horn adjustment along with the other tests. God bless this forum and happy motoring. Quote
greg g Posted September 18, 2009 Report Posted September 18, 2009 Also make sure the horns are firmly attached to the mounting bracket and the bracket is securely fastened to the radiator support. Quote
Arthur1947 Posted September 19, 2009 Report Posted September 19, 2009 Does the horn wiring attach to the radiator frame support with clips? Quote
BobT-47P15 Posted September 20, 2009 Report Posted September 20, 2009 I think there ARE a couple coated clips that snap on the backside of the channel to hold the horn wire in place. Quote
Young Ed Posted September 21, 2009 Report Posted September 21, 2009 I have my horn wire included in that channel in front of the radiator but I believe its mostly intended to hold the headlight and parking light wiring for the passenger side. Quote
