Hello all,

I have an 01 Roadking and I found my horn hanging from it's wires yesterday. For awhile, I've noticed that the horn operated sporadically...something I was going to get to but didn't! My Bad! Anyway, now the horn won't work...I've disconnected it and tried it under a 12 volt power supply and it honks so the horn is ok. I've gone through my Harley manual and I'm not getting 12 volts with ignition on and horn button depressed. I've bypassed the ground, still nothing. However, when I press the horn button, I get about .06 volts and that's about all which would indicate that the button is working? I have also checked the continuity of the horn wires. When I hook up my leads, I get continuity when I press the button. Anyone out there have a clue what else to check on this beast? I can't see any wires frayed under the tank but then again, you can't see much with the tank on! Thanks

 

Try one of these. No wires required!

 

Funny. The new Pee Wee Herman Screamin Eagle Black and Chrome Bar and Shield Automatic Horn. Check your owners manual for proper fitment. DANGER, disconnect battery before installation. Death or Serious Injury may result from improper installation.

 

sounds like a bad ground...

 

+1 on the ground

 

...... do you have a part # for that ?

 

Well, I've checked the ground wire on the horn and it's got continuity to the frame ground. The switch seems good too...it's just lost the 12 volts to it...

 

Take the wire off the switch that leads to the horn and check for continuity. My guess is the switch is bad...

 

Ok, it's not the switch and not the ground...it's the fuc*^$@ fuse! Now...I have the official Harley repair manual that was not cheap...and...does it say anything about checking the Accessory fuse in the Trouble shooting section of the Horn? Nope! It sure doesn't. Even if you go to the Fuse section, it doesn't show you that the Horn is part of the Accessories...I guess you have to assume that the horn is an accessory which does make sense but...one would think that it would be part of the Trouble shooting techniques for stupid people like myself! Anyway, that's what it was...the fuse was blown! Had there been something to tell you to check the fuse, that's the first thing I would have looked at!

 

The next time something electrical doesn't, I bet the first thing you do is check fuses. Good lesson, and fairly cheap, although electrical issues can be very frustrating. Glad you found the problem.
