Default Damn horn!!!

Hey y'all,

I've tried just about everything to get it to work w/o success. I have replaced the horn switch and horn with no success. I put a meter to the horn, it read 12v, hit the horn switch and it dropped to 5v. I believe that reflects a ground issue.
the other thing that puzzles me is that it has two red (power) leads joining the final wire to the switch.
Any idea's out there?

The two red leads are joined by a single heatshrink.

Bring the horn to the battery and do a quick temp wire job.

A picture is worth a thousand words...

Twin trumpet electric horns have two sets of leads, one for each horn

Your horn actively has 12v running through her, but doesn’t work?

you hit the switch, it drops to 5v at the horn and the horn doesn’t work?

Did I read that right?

Correct, all it does is make a single short bonk sound.

still trying to trace them, One should goes the fuse box, the other is the challenge. Everglades seem to be masters at hiding.

My newest boat has the approved / required “horn”..... which is a ridiculously weak / puny electronic buzzer which sound more like it belongs in a child’s toy.
I bought and carry in the helm’s beverage-holder one of the hand-held, refrigerant-driven marine HORNs that make a LOUD, IRRITATING, BLAST....

Now have the best of both worlds... a boat equipped with the minimum equipment which meets the rule... and a Real horn that can get proper attention for just a few bucks.

Don’t waste a lot of time or money on troubleshooting your OEM horn when you can meet the Rule for less than $10 at WalMart.

It isn't in my nature to give up. Besides, I'm retired and I won't charge myself for time spent looking for the issue. 🙃

Horns, and especially the powerful ones require a very clean connection and full voltage. I pulled new cables for my new horns as the old ones just gave it that bonk sound. Pull the thickest wire you can to them and get a new horn switch.

I'd jumper from the battery + & - posts to the leads at the horn to determine if it is a horn or a wiring problem.
If that doesn't provide loud continuous horn sound, I'd adjust the diaphragm tension screw until the diaphragm vibrates as it should, then re-tighten the lock nut.

You have a bad connection or wire. Try using some spare wire to go from batt +ve directly to the horn and if it works your problem is in the +ve wiring run. If it doesn't work use the wire to go direct from batt -ve to the horn -ve and then push the button. If horn works your issue is in the horn -ve wiring.

I had the exact same issue, it was a grouding issue. Mine turned out to be a loose spade connector on the back of the switch panel. Replaced the connector and horn worked. Trace out the ground wire and check all connectors.
