If the shims were messed up, would it either keep the horn on all the time, or keep it from not working at all?

To me, the shims will dictate how much pressure you have to depress the horn for contact. I started with 3, and now down to 2. If anyone needs a schematic of this, I may be able to burn one and set to e mail.

I'll try it and let you know.

I really appreciate all of the post on horn problems. I have run into a succession of problems that I cannot seem to whip.
It first started as described by Tumarr above. When ever I hit a bump, the horn would go blow. If I removed the horn cap, no problem. I could not solve the problem, so I replace the contact with a new unit from Ecklers. I thought I was home free, installed the horn cap and the horns blow without being asked. Again, if I remove the horn cap, the horns work just fine. I presently have two shims between the contact and the spacer. I am now running without a horn cap, but at least I have a horn.
Any ideas will be greatly appreciated.
Thank you,

Most of this stuff was pretty generic inside. Corvette,Camaro, Vega all used the same wheel. I think the the guts were pretty much the same for alot of the Chevrolet wheels. You may be able to get this stuff from a wrecking yard for less if you can't get it in a timely manner from a parts supplier.
Tuxblacray,
Thank you for your reply. I have tried to follow the parts explosion for the assembly and not made much progress. Unfortunatly, the horn had been worked on by the previous owner. They did have the shims in the wrong position, under the lever ring. Do you think it may be the lack of shims? I have two now and if adding more may fix it, I would give it a try.

Adams' Apple,
Thank you. I think the 74 diagram will help. My 75 diagram did not show the .010 clearance measurement betweent the horn cap and the lever.
I will try building up the shims until I have the spacing specified. I really appreciate your help.
