Any one have a diagram on Grant steering whl Horn??

It's very simple. The one wire coming out of the top of the column should ground to the steering wheel.
Sorry to say there isn't a diagram for that.

 

there should be a spring holding the horn button up. Then when you push down it supposed to ground against the steering wheel. You have to figure out a way to isolate the horn button so it's not grounding.

 

I had the same problem when I hooked up my grant wheel. can't remember what I did to fix it, that was over a year ago and it is just too early in the morning. If nobody chimes in. I'll run out to the jeep tonight when I get home and take a look how I wired it.

 

Well, that's the way it's supposed to work anyway. Here's a link to one of their installation sheets:

There is a round phenolic plate that the horn button holds away from a contact plate by way of that spring. As I recall the contact ring is grounded by the fact that it's screwed to the metal of the steering column. The horn wire goes to the phenolic piece. Horn sounds by temporarily grounding the horn button by pushing the horn button against the spring tension which pushes the contact on the phenolic piece against the contact ring. The problem with their design is you only get a few tries when it comes to snapping that chrome horn button on and off the phenolic piece. Eventually it chews up the edge of that phenolic piece and eventually you have no way to snap that main horn button trim piece into place.

Don't get me wrong, I actually like the Grant wheels except for that flakey horn button setup. I had to put one on the M715 a few months ago. The last one I'd installed before that was way back in the late 70s on an old Pinto. They still haven't updated that cheesy horn button setup they use (at least on the less expensive wheels). I even emailed them about it and I guess they didn't like me picking on their superfragilisticfantabulous horn design as they never wrote me back.

Some day I'm going to come up with some modification for those horn buttons that really works. One thing I've done with those sometimes is to expand the spring a little that pushes against the horn button to increase the tension and keep it from going off too easily. Other than that it should work like above.

Unless I'm mistaken there are two wire horns and one wire horns. When I got my grant wheel I didn't have a horn so I borrowed one from my brother's junk bin. The one I borrowed was a two wire and seems like it worked just oposite of a one wire.

By that I mean that the one wire has power to it all the time and the pressing of the horn grounds the thing and completes the process.

I think the two wire horn works the opposite in that pressing the horn sends power to it.

I know that's probably a bunch of molarky but I'm sure someone will chime in with "Actually John...."

 

Actually John, you're right. Some horns want a completed ground circuit and some don't. Have to be careful how you do it!

Besides, I wanted to be first to say "actually John..."

Right, they are real touchy about how you get that trim piece on there. Once it's on you should be OK as long as you don't mash down real hard on it in a panic stop!
