When I connect the negative cable my horn keeps blowing! What is wrong?

As Everett#2390 said it may be the activation wire is grounded or it may be something like I had with an issue of it being a defective replacement horn relay that had internally shorted.
What year, make and model car are you having issues with and what is being used for the horn relay (if one is even being used) ?.
A defective horn relay/key buzzer for my 68 from D&R Classics:
On mine when it had the defective horn relay, the horns kept blaring and I disconnected the wire to the horn but with the relay still energized it got very hot to the touch and also drained the battery down.

does the small green wire with the spade plug go on the terminal furthest from the mounting backing plate of relay,,,or the terminal closest to the mounting plate?

Mine had a stray strand break loose in the steering column. Go straight fine, turn horn honks. Look in the turn signal cancel module to make sure there are no shorts.
After weeks of chasing I found the stray strand, cut it and problem solved.
Retired for a cold one and horn starts blaring in the garage. Open the door to find a neighbor pushing the damn button.

No intermittent horn going off when turning or otherwise, it just does not work
Is the black wire for the horn circuit in steering column +12v or is it ground?
If ground it does not have continuity when I ground it with DVM nor does it meter as +12v if it is positive power

Just honked mine. Obviously hot even without key, so hot push button and honk. If it honks with power connected and button not pushed you have a short. Not fun.
yeah but my ? is....is the black wire that runs through steering column a ground or +12v?
Mine tests negative for both so need to know if it is a power feed to that wire a problem or if it is a ground...the wire may be broken somewhere between horn button and relay

Black wire that runs through steering column is a ground. Check the small spring in the steering wheel area. This spring is usually missing, or broke. I've seen folks use springs from a pen to replace; they usually work well. I've also seen where folks try to jury rig a coiled wire or other methods to replace that spring that short out, but this usually makes the horn blow constantly.
If you have no continuity from this black wire to ground, check that spring and the black wire for breaks.

^^^, thanks. Yeah the spring was missing and in its place the PO or monkey he had install the wheel used a broken fuse using the filament as a "spring contact".
I used the spring from a pen which fit perfect. Great to have a loud horn now
