Adam Posted March 30, 2014 Share Posted March 30, 2014 As the title says my horn doesn't work, I've bought and fitted a new horn in hope it was as easy as that but oh no it still doesn't work!! I've had a look at the wiring I can get too and everything looks as it should. I've even taken the instrument control bit apart and had a look at the connections in there and they're all good so I'm a bit stuck now, bikes MOT was due and has now run out because I can't fix this stupid horn!!!!!! Any ideas? Quote Link to comment Share on other sites More sharing options...

Adam Posted March 30, 2014 Author Share Posted March 30, 2014 Well everything else works though and I had a look at the fuses but there isn't one just for the horn.. Quote Link to comment Share on other sites More sharing options...
Tango Posted March 30, 2014 Share Posted March 30, 2014 Have you tried the horn with the engine running? Horn don't work on my bike unless the engine is running.....was the same on the sprint too..... Quote Link to comment Share on other sites More sharing options...
Adam Posted March 31, 2014 Author Share Posted March 31, 2014 Yeah tried it with the engine running still no joy unfortunately Quote Link to comment Share on other sites More sharing options...
fq-craigus Posted March 31, 2014 Share Posted March 31, 2014 Doesnt a horn have its own fuse supply? The normally do on cars ect, maybe you have tried that already? Get your mulimeter or test light on the wiring to the horn to see if your geting power if not then start looking for obvious areas of chaffing or brittle wires as the wire may have broke inside insulation Quote Link to comment Share on other sites More sharing options...
Mr Fro Posted March 31, 2014 Share Posted March 31, 2014 Go to Maplins/similar and get a spring return switch.Connect switch in line between the battery and horn.Book and pass MOT.Worry about horn problem later. Quote Link to comment Share on other sites More sharing options...

This was my last resort plan, but I wasn't sure if that would pass the mot.. I'll give it a go though, might have to run some new wires for the horn eventually.

Adam Posted March 31, 2014 Author Share Posted March 31, 2014 By the way what wire would I need? 3mm? Quote Link to comment Share on other sites More sharing options...
Mr Fro Posted March 31, 2014 Share Posted March 31, 2014 By the way what wire would I need? 3mm?Nah, that's huge. I've used old speaker wire before - it's only on for a second or two so won't even have a chance to get slightly warm if it's on the small side. It is tempoorary after all. I once got through and MOT by shouting "BEEP" when the tester asked me to press the horn... Quote Link to comment Share on other sites More sharing options...
Adam Posted March 31, 2014 Author Share Posted March 31, 2014 Yeah I was thinking of house wires haha! Got some 60amp wire and a switch from The Range for just over £5 fitted the switch to the handle bar and ran the wire direct from the battery to the switch and back down to the horn, now here's the interesting part when I used the existing earth wire the horn only just about worked AND my side light, neutral light and dash were lighting up (could've been more but they're what I noticed) they were only very dim but it's not good news. That means I've got a bad earth connection somewhere, I hate electrical problems! As a quick fix I've just earthed the horn to the frame and it works fine now, probably could've earthed it in the first place but oh well! Now I've got the joys of finding it !!!

Tango Posted March 31, 2014 Share Posted March 31, 2014 Why?.......just run a new earth wire for the horn......job done..... Quote Link to comment Share on other sites More sharing options...
Stu Posted March 31, 2014 Share Posted March 31, 2014 By the way what wire would I need? 3mm? just for future reference you dont measure wire in mm you measure it in load IE how many amps it does sound like you have a bad earth there wont be many earth connections on the bike probably one main one and a few places in the loom that will need a clean up main culprits are where multi plugs are get a wiring diagram just make sure everything else works fine before you go for MOT like indicators with lights on too and also whilst holding the brake on Quote Link to comment Share on other sites More sharing options...
Adam Posted April 1, 2014 Author Share Posted April 1, 2014 I'll try tightening up the main earth connection to the frame if that doesn't work I'll have to start searching. Took it in for its mot and it failed but only on stupid little things which were 1. Headlight needs adjusting. 2. Chain link clip wrong way round. Second one was my bad, but both are sorted now and I'm dropping the bike off before work and they're going to re mot it for free Andy (the owner) said he would've sorted both things himself if he had the time but he's super busy at the moment which is fair enough. Top blokes over there at ABC Motorcycles in Norwich if anyone is local I highly recommend them. Cheers for all the help again guys! Quote Link to comment Share on other sites More sharing options...
Stu Posted April 1, 2014 Share Posted April 1, 2014 they cant be that great as it failed you need to remove the earth and clean it up I am betting its a rubbish connection somewhere on the loom and not the main earth otherwise you would have trouble starting etc Quote Link to comment Share on other sites More sharing options...
Adam Posted April 1, 2014 Author Share Posted April 1, 2014 Funny you should say that, I have had trouble wit it starting. It's seems the battery is discharging by itself, the other day when I was doing something to it I noticed a buzzing noise which turned into a click noise which got faster and faster then stopped and after a few minute the cycle repeated itself. Ignition was off and I even flicked the kill switch but it was still doing it. I normally have to charge the battery once a week and if I don't it struggles to start the dash goes blank and it sounds terrible! Usually it starts though and then the next time I start it it's fine very strange! Quote Link to comment Share on other sites More sharing options...
Stu Posted April 1, 2014 Share Posted April 1, 2014 sounds like you have an electrical short to me Quote Link to comment Share on other sites More sharing options...
