Not really if you think about it like this.
"The Battery Energy circuit is run into the diaphram of the horn and that Energy is converted and dispursed in the form of sound"! Most all electrical circuits while "Operating" are a direct short, that's what makes you horn sound.
If your horn switch is depressed, then the circuit is on/"closed" and the horn sounds and the circuit reads a short.
If the horn switch is not depressed, then the circuit is off/"open" and the horn should NOT sound, nor should the circuit read as a short.
Between Mr. Wizard and BadBrad I was learned this, because John Sachs said soo!

Not exactly...
According to the schematic the horn is connected directly to the battery negative. That would mean it turns on when you supply power by pressing the button. It's not ground switched as you suggest Ray.
If the bike works fine with the horn disconnected that would tell me the gray wire on the horn doesn't have any shorts to ground or the problem would be there all the time. So, the horn itself seems to be the culprit.

Either the person that told you is incorrect or the 2003 schematic that BD supplied is incorrect.
On the Big Dogs that use the newer EHC, components are turned when the switches supply a ground to the EHC which in turn supplies POWER to the component, like the headlamp or horn relay. But, the horn on the 2003 Big Dog doesn't work that way...

You were right about it being a momentary switch. It's only "on" while you're pressing it... :up:

Yeh.... I pulled the tank over the weekend to see if any wires looked chafed of kinked. All appeared to look good so I re mounted the tank. Tried to disconnect the headlight so I could see if the horn would work with less amp draw but couldn’t get that bulb-retaining ring out. I guess I just need to go through it with an amp meter to see where im drawing all the amps. Won’t be able to get back to it till after the holidays. The horn worked in the car that I took it out of and it works on the bike. It just kills the engine if I honk it with the motor running.

Kool,
Then maybe you can just honk it with the motor "NOT" running.
Have a Merry Christmas and a Happy New Year!

the symbol in question ont the schematic is a Poly fuse otherwise known as a PTC. Think if it as a sold state fuse that will reset when fault is removed.

The horn power comes through "J2" #7 of the EHC.
You could take the wire out of the plug, P2 is the plug, wire position is #7 (green) and hook it to J4 #2 (Grey) @ EHC and eliminate the EHC all together.
Just keep in mind that your switch on the bar is now handling the current from the horn.
The electronic circuit breaker will still be protecting the circuit, but it may be questionable if the horn switch/button will handle the 3.5 amps.
But you can temporarily hook a relay up to handle the load.
I'll draw that circuit for you if you decide to use a relay. 3.5 amps is not much and the switch will probably handle the load.
Hope this helps...
PS. it looks like a bad EHC ? I would wire a separate circuit for the horn if needed

Damn Gabe that took some work, good job. :2thumbs:
To bad the Kool man is just a funkin myth, I thought I saw him once at Leesburg hauling azz the other way?:loony:
This is the best part of this site. Members helping others.
Thanks guys.
