Technical 55 210 Horn issues

I have a 55 210, completely rewired with an off-brand universal wiring kit, aftermarket horn.

Horn keeps blowing when I hook it up. Replaced the steering bushing that was really worn out and had several cuts in the wire. New bushing did the same thing.

Figured out if I didn’t push the new bushing all the way into place, it would work correctly. If I push it all the way into place, horn wire would make constant connection.

Got a new steering bushing today, installed it, gown worked correctly. ….for about 10 minutes. The. It just started blaring.

any idea what the issue could be or what my next step should be for getting it to work correctly?

(new mooneyes steering wheel if that makes any difference)

 

the bushing went all the way in when you started driving. So you need to figure out why it shorts when it goes in all the way.

You're gonna have to post some pictures of what you're working on, for us to be able to help you.

 

What parts should I take pictures of? Should I take the steering wheel back off and pictures of the bushing?

 

Hey Mikey, welcome.
You may not have seen the 55 two-ten thread, would like to see your car posted there, maybe you can get some answers

Done several tri fives the horn is picky. One time no issues next time some sort issue.
Double check the green horn wire from beginning to end at horn.

 

I have. The green wire is good. I just took the steering wheel back apart. If I pry the steering bushing out just a little, horn works as it should. If I push it all the way into place, it makes constant contact.

 

Without seeing a picture this is just a shot in the dark. Can you try putting some plastic washers behind it so it can't be pushed in any further?

 

I’ve tries uploading pictures, but it keeps saying “file too big”

 

Appears the insulation under the shoulder of bushing is non existent or breached.

 

Remove the bushing, and look at it to see if you can see what could be shorting. Look in the hole in the column, as well. Pictures of your bushing, in the position of the other one shown above, will let us see where the problem might be.

 

About having the bushing elevated and no issue. What steering wheel? All steering wheel horn related parts correct? If contact pin is over extended in length it will wonder and do funny things.

 

It’s a mooneyes grant style steering wheel. All the steering wheel mounting and horn parts are correct for that steering wheel

 

Ya, but it’s all aftermarket. Grants are fun to get right.

 

It looks like you fed the wire into the turn signal housing? It's supposed to go straight down in the column. I wonder if that is messing it up somehow?

 

I did run it that way. I’ll see if I can re route it tomorrow and give that a shot.

 

Good catch.

 

Woke up this morning thinking wait a minute. The shift tube and shift collar will not allow the horn wire to go straight down. Been at least 3 years since I tore into one. Be it 57 however same internal set up.
Out in the shed I have a 55-56 column. The shift tube goes into the shift collar then into the signal housing as a pivot point so no passage that way. The wire has to run outside of shift tube making Op’s route correct.

 

thanks, been a long time since I fiddled with one that still shifted on the column.

there has to be something making it not work...I think the first thing to check would be resistance to ground to the contact, with the relay disconnected, and the bushing fully inserted. An ohm meter is going to be pretty handy to help figure this out.

 

The wire goes between the shift and the column. Comes out of column just below the dash.
I’ve always had issues using after market kits.

 

The bit I don’t understand is why it’s blowing the fuse. The horn contact grounds the horn circuit and the horn makes noise. If the collar wasn’t insulated properly youd just get the horn sounding not the fuse blowing. For the fuse to blow there has to be something else wrong doesn’t there? Have you wired the circuit correctly to begin with?

 

Fuse? What did I miss?

 

Fucking idiot aren’t I! Blowing the horn not blowing a fuse. Doh!!

 

To stop you (and the neighbours) going insane when working on a horn, replace the horn with a light globe and place it on the windscreen so you can see it. I did this after my wife came out and thought I had injured myself and was trying to signal for "Help"!
