Air horns???

[julieR]

Horns on the roof, look like electric air horns. When honking horn on steering wheel, horn under hood honks, not the roof horns. HOW to tell if the roof horns are hooked up? Where do they hook up? How??? Are they really air horns, or just for looks?

Hi Julie

My 99 Tradewinds has a switch on the driver armrest area thats labled "City Horn" and "highway Horn" when in the city position it acts like yours, when in the Highway position it switches to the Air Horns on the Roof.
Have a look around for a switch like that.
What kind of coach do you have?

Thank you Dick. I have a 2003 Dolphin, by National. I have looked, no switch. There are 2 AUX switches, one on left side, one on right just above the radio controls. Flipped them, no difference. We bought the Dolphin new, and just always thought the "regular" horn sound came from the "bells" on the roof. I sure do want an airhorn!!

The 2003 Dolphin LX spec sheet says CHROME ELECTRIC HORNS.

When I was investigating my non-functional day running lights and working with the relay modules under the dash access cover (Workhorse items), I found that the horn relay was plugged in upside down. After fixing that, one of the two roof horns blows rather anemically. I tested by disconnecting the chassis horns. More diagnosis I guess. Don't expect too much.
Thinking about putting a Wolo Bad Boy horn under the hood for $30. Anyone try one? I understand they are loud but high pitched.

There are many electric air horns available, generally starting about $10 at Harbor freight. Also quite a few at JC Whitney

You must use a relay. We went with a medium price from Harbor freight and just wanted to see what the improvement in noise was. 4 1/2 years later, and they are working fine.

They do get the attention of the other drivers. There is plenty of space on the curb side, above the air cleaner box. "Trumpet" end just stick out behind the grill. Does wake people up.

Who makes the electric air horns? I just hit mine with a low branch this week and need to replace them.

My last RV had twin air horns and my new coach one did not come with them. I am planning on getting train horns . I really don't want to add more holes in the roof and cleaning air horns of bugs & dirt that high up is a chore and the coastal fog and salt air pits chrome over time.
I was thinking of mounting a set of horn blasters under the front of the RV, behind the grill, below and ahead of the radiator. Has anyone done this

I installed a Wolo Bad Boy in the engine compartment, and am VERY satisfied with tone and volume.

Several years ago, I went through this same deal. The roof mounted horns were basically useless after a couple years. I bought a 12v compressor from a place called "Siege Engineering". I mounted it in the compartment under the charger/inverter. I found a set of Kenworth horns on ebay and mounted them where the electric horns had been. It required cutting a set of holes in the roof right above the driver. I did this my removing the left side speaker. This provided access to connect the air. I ran the air line over into the cabinet where I installed the valve. The line then ran down the window post with the the other wiring. The line is 1/4" water line from Home Depot. It then goes through the firewall and down the right side to the compressor. After all this, I still was not satisfied with the sound so I added a single fire truck horn mounted in front of the firewall on the passenger side. The horn is pointing down. The two valves are wired to a relay that is controlled by a switch located on the steering wheel right under my left thumb. Needless to say, I am more than satisfied with the sound now.
