Howdy Y'all. I am trying to figure out why the horns will not blow on my freinds 46 Packard Clipper. I puts off until I could gem my trusty Power Probe 2 figuring I could stumble thru this POSITIVE Ground thing. Wrong! I figured it would be the same as Negative ground just in reverse. Well I dont know where& how to proceed. It has Dual Horns A high & low tone & the relay is right there . I can not get the relay to click from the horn buttton ring. But can get it to click if I jump a wire to the relay on the "S"(NEG) with the Bracket ( now removed off the head for access) Positively grounded I can get the relay to click & the horns sort of want to work almost getting a tone for a fraction of a second. This is my 1st dealings ever with 6 volt, & positive grounding systems. PLUS I never really got a great grasp on how the horn systems worked I think its a grounding in the horn ring that makes it work.. SOOoooo HELP! PPPPlease! Thanks so much for your time SR66
There should be a power feed to the horn relay that is on all the time. A wire from the relay that goes to the bottom of the steering box, up the steering column to the horn button. The horn button grounds it out. This makes the relay click, feeding power to the horns. So, have you got power to the relay? Does the horn button ground it? Does this feed juice to the horns? Once that is all working the only thing left is the horns, froze up or not grounding.
Don't know if this will be of any help, but here is the horn contact setup on a 1946-48 Plymouth. The Packard could be similar. The horn wire on the Plymouth runs down thru the steering column and out thru a hole in the steering box. That wire can either break or come loose from the portion inside the wheel center. Do you have a wiring diagram for that car showing where the horn wiring goes? Make sure any connections are clean. There's a good chance the honking mechanism inside the horns themselves is OK, unless they were at sometime abused and might be rusty or very dirty. Then, there is the relay. Sounds like it's trying to work. The best source of info is a service manual for the car, and a wiring diagram.
Thanks everyone I went back to basics & started by cleaning up connections & got it back functioning. Damn that suckers loud Thanks again SR66
