Horn stuck on

Hi,

Does the horn stop if you remove the relay? I'm trying to determine if there is a short to power after the relay. Also, how was the relay inspected? Take a look at this link that explains how to test a relay:

If the relay tests good, then I suspect the actual switch (horn button) in the column is the cause. I attached a wiring schematic of the horn circuit. Take a look and you'll see there isn't much more to fail other than a shorted wire.

Let me know about the relay and if it stops when the relay is removed.

Take care,
Joe

Yes, it stopped once I removed the relay.(that was the only way to shut it up).This is the way I tested it: pulled it out connected jumper wire to one control terminal (85) and batt +,the other control terminal (86) to batt -,it clicked ,then checked for continuity, at the power terminals (87 and 30) .It had continuity..
Thx for the fast response and help..

After you guys answered my original question, I went ahead and took a voltage reading at the fuse box and got live volt on the top 2 connectors, where the horn relay goes.
Is this normal?
Thanks again for your help.
