 Subject: Horn Problem...
IP: Logged
Message:
...So today I finally got some new horns to to get rid of the wussy stock ones. A friend of mine has these in his truck and they sound pretty good. Anyway, to connect these, I cut the stock plugs off of the wires and put on slide connects which plug into the new horns. After doing this, they will not work. I keep blowing fuses. These are standard 12 volt horns and the stock relay. I dont get it. Could this be the relay? Any ideas are welcome.
appreciate it,
-Nick

It sounds like a short circuit. It is probably not the relay if it worked before. How may connectors are on the new horns? If there are two, possibly you have them reversed- grounding out the hot (through the case).
There are several things you can try. First, disconnect the truck wires from the new horns and see if the fuse still blows. Then, test each horn "individually" with separate wires to the battery (to confirm the new horns are good).(+) is the hot and (-) is the ground. This should isolate the problem; a defective horn or a wiring problem.
Another possibility is everything is wired correctly, except they draw so much current, the fuse blows. When you connect the new horns to the truck wires, try connecting one first.

also, make sure the new connectors are not touching. this will blow the fuse also.

You should not have to use the relay you talked
about if all you're doing is replacing the stock
horns in front of the truck.
Sounds like to me that if you did indeed use the
relay, you wired it wrong thus blowing a fuse as
soon at you push your horn button...

The thing is, I've tried some of that stuff. The horns definatly work. I tested them on the battery. As for the connections, I have them connected properly... I tried both ways. I tried each horn by itself. No luck. Im starting to think that when I put in the slide clips, I must have cut the wire farther back, or pulled something loose farther back. Im going to pick up some higher ampage fuses on my way home today and give that a shot. What worries me, is that the fuse for the horns also is the fuse for the A/C. So if the A/C is running, and I hit the horn... Ill blow a fuse. Oh well, I'll try some more things. Thanks guys I appreciate it,

Hey Nick, you should be aware that:
-The fuse in there now is sized to protect the original configuration.
-While it's probably ok to use an oversize fuse for a little testing, if you leave it in long term the next weakest link in the circuit becomes the "fuse."
-That weak link could be a wire that will overheat (fire), or your compressor (more fire, failure), or anything else in the circuit (lots of fire and failures.)
If the fuse blows when the horn blows and nothing else on the circuit is on (AC compressor, lights, whatever) here's some things to check:
-Do a horn test as suggested earlier by irq3.
If that reveals nothing:
-Do a little "horn research." Check current draw of horn(s) (look on box, call mfg., etc.) and compare to fuse size. Unfortunately this can be a little misleading as most things have a higher initial draw than steady-state.
If the horn seems to blow mostly when other items in the circuit are drawing juice also then it's highly likely you are just trying to suck too much juice through that fuse. In that case the SAFE thing to do would be to give the horns to your little brother for his bike and follow QuadMXRacer's advice and get a stand-alone system.
If you have or know someone handy with a multimeter you can check for shorts, current draw, etc.; that could help figure out your problem quickly.
Good luck and happy horning.
