I will post the pic shortly. The spring does go under the cam. I've had it that way the whole time. After the post suggesting the spring was on top, I checked the resto guide to ensure I had it right.

Not sure why the first one was sideways.....

So is the horn going off as it sits in the picture, with no other pieces installed?

[jadams]

No. When everything is hooked up the horn blows.

[GOLDOHC]

When you install the lock plate-cancelling cam the horn blows? Could you post a picture of it installed?

[jadams]

Yes. I will post a pic tomorrow. I did the test light as suggested. It stays on until I pull the lock plate off of the copper pin on the turn signal switch.
Can I ask what you are looking for with the pic?
Thanks for the help.

[Pepi]

Does it blow with the lock plate off and you pushing down on the white horn slip-ring piece?

[jadams]

I'm guessing you mean the cancel cam?
No. When the lock plate is off and I push on the cancel cam it does not blow.
I did just notice that the brass strip on the back of the cancel cam has tabs that come to the front. The lock plate is touching those brass tabs. I would bet that is causing the constant ground I am getting thus causing the horn to blow.
Is there supposed to be something between the cam and the lock plate?
I just looked at a cam in the Ames catalog and it looks like it has a rubber gasket on the top of it.

I am trying to remember if I every saw where there was a thin plastic piece between the lock plate and cancel cam. But it sounds like that is the problem. Do you have a parts breakdown of the steering column?

[jadams]

I do but it shows nothing between the cam and plate. I wonder if the plastic gasket - or whatever it is - is part of the cam......?
I'm going to make something to put between the two and try it this evening.

[jadams]

Horn works!!!
Apparently the lock cam was touching the brass tabs on the front of the cancel cam causing a ground.... Whodathunk??
I took a door panel water shield that I'm not using, cut a piece out to fit between the two and viola!!
Thanks a million for all of you guys help. Although I feel kinda dumb, I learned a ton from all the advice. Most importantly...check the simple stuff first!!
Oh well. Horn works and I never have to worry about a new relay or turn signal switch.
Thanks again to everyone!!!

I don't think there's supposed to be anything between them. Just a thought -- I wonder if the lock plate is on upside down. If that's possible, would that do it?

Edit: jadams, did you have to use a lockplate depressor tool to take the lockplate off? If you didn't need to, something is wrong (like maybe the plate is on upside down).

[jadams]

It's not. I checked that. Bevel is pointing up towards the steering wheel.
Strange, I know. Possibly a flaw in the cancel cam? Who knows....

[LPete]

Gotcha. Interesting...

Glad you figured it out.

[jadams]

And yes.....I had to use the depressor.

[jadams]

Some good useless knowledge for somewhere down the road I guess......

Thanks
