Hey Guys...the damn horn on my 67 wont honk. I posted this question some time ago and I did almost all the suggestions that people gave me. The horn works with power directly to it, and the relay is brand new. Someone said check the ragjoint. I would assume that this is the fiberous disk that connects the steering wheel shaft to the steering box...replaced that. It helped tremedously in the steering, but still no horn. Can someone let me know what they think I should check next...please!!!

Ken

 

Are you removing the horn from being attached when you put a constant 12 volts to it?
Or are you leaving it attached ?
I'm thinking bad Ground if attached,but if you're putting a wire directly to the horn from the battery when it's removed.........

Ken, Make a ground through or around the rag joint on the steering shaft. I have noticed some have builtin grounds. I found it by using a 1 1/2" wire from the upper to lower side of the joint. Horn blows great now.

I didn't get in on your earlier post, so I may repeat something you've already heard. If I do, I apologize for the repetition.

The connector at the horn relay has three wires. One feeds 12 volts to the horn when the relay is engerized. A second brings the 12 volts in from the fuse block. The third comes from the steering column and provides a ground when the horn button (ring) is pushed. The ground is obtained through the steering shaft, bearings, steering housing, etc. If the shaft is insulated in some way the horn won't work because there is no ground to activate the relay.

I suggest the following steps:

1. Remove the connector from the relay and check for 12 volts on one of the three connectors in the wiring plug. If it is there, continue to step two. If it is not, check the fuse or troubleshoot for a an open wire.

2. Using a spare piece of insulated wire, jumper the 12 volts in the connector to one of the other two (this assumes that the wire from the steering column does not have a short to ground -- it should not, since the horn doesn't work). The horn should honk if the jumper connection is good. If it doesn't honk, troubleshoot the wire from the relay to the first horn for a open. If it does honk, goe to step three.

3. The wire that goes up into the steering column for the horn on your '67 should be blue with a yellow stripe. Hook the connector to the horn relay and locate the blue/yellow wire under the dash where it comes out of the steering column. Using a sharp pointed implement (I use an awl) and a piece of wire, push the point through the insulation to short the blue/yelllow wire to a good clean ground. The horn should honk. If it does, troubleshoot your steering column wiring or horn button for an open circuit. Remember the possiblility of the steering shaft being insulated and not providing a good ground (although this is remote, keep it in mind).

I'm sure that this is more than you ever wanted to know about a horn circuit.

I jumpered the rag joint and mine works great every time

Guys...thanks so far...how the hell do you jump the rag joint??? What am I supposed to ground? Won't a wire get twisted up when the shaft turns???

PLEEEEEEEEEEEEEEEEEEEEEEEEEEEEASE HELP!!!

Ken

 

Ken, You have two metal shafts seperated by about 3/8" of a tire like substance. You need to make a jumper from the upper steel to the lower. The two pieces are turning in unicence so there is no problem with twisting. You need to give it a close look and I think it will become clear. You loosen one nut and start the wire and then the other to complete the ground.

Ken I'm in Durham NC, bring it by my place and I'll give you a hand if you are close enough.

Hey John--

Thanks for the offer...but I live in Temperance, MI which is just south of Ann Arbor. Anyways, Dad has promised me that we could look at it this weekend, so I will let you guys know.

Ken

 

Hey Guys...problem solved...well kinda. It turns out the ground was bad in the shaft. Fixed that. The one contact brush inside the column is bad...so Dad and I temporarily fixed it by making a new one with a spare piece of wire. It will work til the new one gets here from LMC. Thanks again guys.

Ken

 

you say 'one wire brush' was bad...by chance, does that mean you have two brushes under the horn button?

thanks,
sam

 

Yes I do Sam...why do you ask???

Ken

 

 

the reason i ask is, i'm having similiar problems...my horn honks fine, but only when i ground the shaft to the horn wire on my turn signal switch.

but there's only one brush, which is sitting in the socket on the turn signal switch. do you have a brush under the button, as well in the socket?

thanks,
sam
