Case DX24E horn relay

Would anyone know where the horn relay is located?
I have a dead short when the horn button is pressed, blows the fuse. Switch gear looks okay, I disassembled it.
Thanks in advance to everyone

You could try disconnecting the horn itself to see if it's shorted. I doubt the relay is the problem. You may have a mouse or rubbing problem which has caused a bare spot and is shorting directly to ground when the horn button is pressed. Try replacing the fuse with a twelve volt light bulb for testing purposes. The short will allow it to burn brightly. When you eliminate the short it will be much more dim.

Roadworthy,
Followed most of your advice. Determined that the horn circuit is not the issue. The problem appears to centered around the turn signal. Blows a fuse when the left turn indicator is applied

The same principles apply. You could try a jumper with a bulb in series to limit current then try to determine if it's a front or rear turn signal by powering one at a time from the switch. After that it's a matter of actually locating the short.
