Not good! And so started the investigation. The WOF guy was not much use to me and after pressing the horn button himself a few times (and probably damaging it - see further down) left me to it.
As everything was dead I naturally assumed it was a fuse - but which one, and where was it hiding? I figured it must be the main fuse as I had no ignition but the first fuse box I looked in just had accessory type fuses in it. Where was the main? Time for some googling on my phone...
|Thar she blows!|
New fuse in, I flicked on the key and was back in action again. That is, until I hit the horn - oops there goes another fuse. With no spares left I wandered across the road to a garage and bought another one (actually a packet of them but only one 30 amp).
As I replaced the fuse I decided I would not touch the horn again, just ride home, sort out whatever was going wrong and then come back to finish off the warrant. This time when I turned the key on the horn instantly came on! I quickly turned the key off, got my warrant so I was legal again, disconnected the horn (back to illegal again I guess) and got myself home for further diagnosis.
The first thing I noticed when I got home was that the horn button looked like it was pushed in - it was almost flush with the switch block.
Well, that gave me a starting point...
|Not really sure if I want to be pulling this apart...|
Sure enough the spring under the horn button had been crushed so the horn was button was not returning after being pushed.
I managed to fix up the spring (I will need a new one at some stage) and then get everything back together properly. I then hooked the horn back up to the battery again and turned the key on.
No blaring horn so that was a good start, now to press the horn button - click, click...Not good. So there was something else wrong somewhere - the relay seemed to be clicking....hmmmm. I know let's just ignore it for a few weeks....
Fast forward to today and I started pulling things apart so I could check wiring and plugs etc. When I pulled the little front, lower cowling off the front of the bike so I could get at the Stebel a whole lot of little stones fell out but the wires to the horn looked good.
All the other connections and wiring looked ok - what now? I know, let's try the horn - Baaarrrrrrrrppppppp! Great, the horn works, but why?
So now I have a working horn but do I still have some mysterious gremlin lurking in the wiring, waiting for me to be way out the back of beyond so that it can ruin my day? Who knows - I hope not, watch this space...
