My horn doesn't work. I've been trying to fix this gremlin for a long time.

Its not the switch and its not the horn. I tried putting dielectric grease in the connector cable that goes from the handlebars to the cable passing thru the engine compartment. That did not seem to work.

I am asking those who might have a similar problem with the same bike to let me know what was their fix.

Thanks
 
Most often it's the ground

What about the ground?
Its not coded black or red so I have no idea which is which. Plus, its bundled with a group of wires. Damn I gotta look at the wiring in the manual
 
you need to get your ohm meter out and find the positive lead back to the button, the other wire should be ground in the harness. isolate the horn and test it to the battery. you may have to open the handlebar switch to clean the contacts.
 
Its weird that sometimes the horn works and does not work. It seems to work when the engine is cold, so weird.

I've put a voltmeter to the plug of the horn and there is not voltage there, when I try to beep it.

Dielectric grease is an insulator. I don't know if that's what you did, but don't put it on connectors.
 
Once you clean the contacts on both sides of the electrical connection, you put dielectric grease to seal out and and the weather. This reduces corrosion and dirt buildup. Dielectric grease is not a conductor.

"Ground" is the negative connector from your battery to your frame. It is usually a green wire attached to your frame.

You have an electrical gremlin somewhere. Get an electrical schematic for your bike. Photocopy it and go through and clean each and every connection, switch, light bulb, etc. After you clean a connection, add dlelectric grease to seal out the weather. Use a multimeter to check all connections. Cross off the connection on your electrical schematic one you have cleaned it. A bike that has electrical gremlins will continue to drive you crazy and your bike will be somewhat unreliable.

Thanks.

Didn't want to tear the whole bike apart to fix the horn tho. I guess I'll get to it when I am free one day.
 
Have you checked the relay? Probably under the seat somewhere, with the other (headlamp, indicator, etc.) relays.

Actually, thats a really good idea.
