Horn Wiring
I just received my New Wiring Harness for 30' Tudor & all my old wiring was any color anywhere, I want to be sure, does the Solid Yellow horn wire go to the contact soldered to the insulated plate inside the horn & Blue & Yellow wire to the grounded terminal? I have wiring diagrams from a few sources but they just show the wires running into the horn but not specified. Thanx!

Re: Horn Wiring
i was just looking in Les Andrews book vol.1, and i don't think that it matters. its not labeled in the horn is it i think i just loosened the screw and pushed them in the contacts and retightened the screw. JAN. the horn button when pushed just completes the circut.

Re: Horn Wiring
Neither contact in the horn should be grounded on a original horn. It is grounded thru the horn button connection ( blue and yellow wire).

The horn body does not need or use a ground, as the horn button grounds the horn circuit. Jerry types faster! |

Here is one with the wire colors.

Re: Horn Wiring
I had an instance where I disconnected my horn and when I reconnected it, it didn't work. I switched the wires and presto, Ahooga! I think the polarity matters as far a direction the motor spins and the ratchet function that makes the noise..... thoughts?

Re: Horn Wiring
The motor is series wound, so when you change the field polarity you also change the armature polarity, and the motor still spins the same direction.

Re: Horn Wiring
Thanx for the help since it doesn't seem to matter I'll just connect the solid yellow to the insulated connection & let the blue/yellow be grounded thru the horn button. It's amazing how many wires the former owners had just cut off & some were still hot at the other end, glad i just went with the whole new harness, I just hope the conact plate at the bottom of the spider switch all works OK, I'm sure it's a repo. Thanx to all again.

Re: Horn Wiring
Mike V. Is that colored schematic available on a 11x22 in. drawing? It would make a great wall hanging in my garage. I might even fold it up and throw it under the floor mat for trouble shooting on the road. Ed

Re: Horn Wiring
It's a pretty big drawing but I don't know the actual size. It's at least 11x17.

Re: Horn Wiring
Hello, I have what looks to be a model A style horn that has been restored and powder coated. It looks like a spartan but there is no tag. Might be replica but the inside looks old.
Anyway, I want to install it in my 2013 car (sorry, not a ford). I was trying to decide if I run it on 12v battery or get a converter to step it down to 6v. First I ran it on 12v and it gave a great loud sound. But I want to try it at 6v so I ordered a converter that arrives in a couple days. I hope at 6v it gives a better natural sound. I'll let you know how it works out. Also, does it matter which terminal I connect + or - wire to? No problem with reverse polarity? My horn didn't have wires when I acquired it so I wired it with 14 gauge. |

Re: Horn Wiring
The horns of the time were probably all series wound as Tom W says above, and polarity shouldn't matter. Your converter should be capable of at least 6 amps output, but a smaller one would probably work ok for a few honks at a time. There should also be a screw for tone adjustment. 18 gauge is sufficient, larger is ok.
(So what it's an 8-year-old thread. Still on-topic. No biggie.) |

Re: Horn Wiring
Thank you @badpuppy. Well, the converter to 6v didn't produce any sound whatsoever.
I used this https://www.amazon.com/gp/aw/d/B00CG...b_b_asin_title But I see now that it is only 3 amp output max :-) so I guess I need to find another one that can output at least 6 amps, correct? |

Go to a Model A vendor close to you (to save shipping) and look up "horn resistor". Here is one from Mikes Afordable. https://www.mikes-afordable.com/product/A13820B.html
