Kurtisvdubber Posted July 5, 2016 Report Share Posted July 5, 2016 I'm wondering if someone can help me.. my horn does not work it has a momo steering wheel and a momo horn.. there is only one wire to connect the horn button but 2 wires on the back of the button.. so I'm guessing the other will be an earth?? I can't hear the relay clicking behind the fuse box under the steering wheel can someone please help me?? Am I missing a wire or is my horn relay done?? I can't find anything anywhere Google is rubbish so I'm in need of help from the fello Lupo Dubbers cheers all Quote Link to comment Share on other sites More sharing options...
Mobieus_uk Posted July 12, 2016 Report Share Posted July 12, 2016 the horn is prolly earthing though a bracket, would take it off and give the point it connects to the car a good clean and the point the horn connects to the bracket just to make sure its not a earthing fault, if still no joy check to see if your getting 12v to the horn 1 Quote Link to comment Share on other sites More sharing options...
cj1 Posted July 13, 2016 Report Share Posted July 13, 2016 (edited) The horn on this works by earthing to the steering column... On my OMP one the wire should be connected to the terminal on the horn button that can move (one is fixed). There is no live wire needed for the button itself. Is the relay clicking when you press the button? Check that the button is properly fixed in, with the connections properly functioning on the back of it (IE touching the wheel/boss when pushed in). Also, did you use the silver ring that comes with it, sits inbetween the wheel and the boss? Edited July 13, 2016 by cj1 Quote Link to comment Share on other sites More sharing options...

Was this working before you put the steering wheel in? Quote Link to comment Share on other sites More sharing options...
Kurtisvdubber Posted July 14, 2016 Author Report Share Posted July 14, 2016 I bought the car like that I had to buy the horn button as it didn't come with one it just had a momo steering wheel and boss kit mate Quote Link to comment Share on other sites More sharing options...
cj1 Posted July 15, 2016 Report Share Posted July 15, 2016 Can you post pictures of 1) How the steering wheel is attached (specifically around the centre ring where horn button goes) And 2) The back of your horn button. 1 Quote Link to comment Share on other sites More sharing options...

cj1 Posted July 19, 2016 Report Share Posted July 19, 2016 Ok, so firstly, take both of them wires off the horn button. The inside the steering wheel, the red spade tag, push that onto one of the terminals on the horn and push it back in fully, and test, if the button is in properly I'd expect this to work. (You will have to try both connections on the horn if it doesn't work first time) :-), Quote Link to comment Share on other sites More sharing options...
cj1 Posted July 19, 2016 Report Share Posted July 19, 2016 In fact, presuming that whoever had the button wired it and used colours that meant something , put the red tag onto the one where the green/yellow one is as a first go. Quote Link to comment Share on other sites More sharing options...
Kurtisvdubber Posted July 20, 2016 Author Report Share Posted July 20, 2016 You have been a massive help mate and I appreciate it so much but unfortunately Nome of these methods have worked I've been looking online and there is a metal spacer/plate that you put in between the boss kit and the steering wheel do I need one of these?? I don't know if it's a live fault or an earth but I'm greatful mate thank you Quote Link to comment Share on other sites More sharing options...
Kurtisvdubber Posted July 20, 2016 Author Report Share Posted July 20, 2016 I can't even hear the relay clicking Quote Link to comment Share on other sites More sharing options...
cj1 Posted July 20, 2016 Report Share Posted July 20, 2016 Ok so I'm not 100% on the ring. But what I do know is the metal U sort of shape must be touching something that is conductive on the column, ie the wheel or the ring. with the steering wheel boss connected and ignition on, touch the wire that comes off the boss to the top of your steering column ( the multi splined part where the boss attached), does the horn work then?

Kurtisvdubber Posted July 21, 2016 Author Report Share Posted July 21, 2016 I've touched the wire that come up for the horn and touched it with my steering column and the horn does not work.. I've taken the horn off and wired it up to the battery and it works fine but when I connet the horn back up there is nothing going on.. I still Cant hear the relay clicking behind the fuse Box when I touch the wire to the steering column or when it's connected to the battery Quote Link to comment Share on other sites More sharing options...

Check that! Quote Link to comment Share on other sites More sharing options...
Kurtisvdubber Posted July 21, 2016 Author Report Share Posted July 21, 2016 Which fuse is it mate haha.. it is probably something so simple haha but you've been a massive help mate Quote Link to comment Share on other sites More sharing options...
cj1 Posted July 21, 2016 Report Share Posted July 21, 2016 ha! There we go, it's fuse 19, almost certain! (Second row, second one in), on yours the contacts are there but no fuse! Not sure off the top of my head what amp it is, but stick one of the others in there for now and test it, maybe a 10A one! Why that's missing I guess is a mystery? Also, are you dewipered? I notice fuse 6 is missing which is for that. Quote Link to comment Share on other sites More sharing options...
Kurtisvdubber Posted July 21, 2016 Author Report Share Posted July 21, 2016 Omg you are a proper lad your a God!! It works mate!!! and I have no wiper on the rear if that is what you mean buddy?? Honestly I'm so greatful thank you so much:) Quote Link to comment Share on other sites More sharing options...
cj1 Posted July 21, 2016 Report Share Posted July 21, 2016 Yeah just noticed the rear wiper fuse was missing as well, but if it's not there then happy days! haha no worries! Had to be something simple didn't it! 1 Quote Link to comment Share on other sites More sharing options...
