Triumph Herald Horn

[andyjwill]

Hi

The horn on my Herald aren’t working. Got through last MOT by removing wire from one of them. Now nothing. Just a click or very quiet sound from them. 

Do I need new horns or can they be saved?

thanks

Have you got a multi-meter? If so measure the resistance across the horn terminals - no idea what it should be - but it should be something I would guess around a few ohms to a couple of KOhms  - but definitely not nothing and not >MOhms

You may be able to save them, there is an adjuster in the middle, with a locknut. If you can fiddle with that it may help.

Never done it, but I think you can drill teh rivets out and take them apart. But in all honesty about £10 buys a new pair or repro horns that seem to work well. Or if you want a decenthooter, try a stebel Nautilas. They are a serious bit of kit, about £25 but flippin loud! (always scares the MoT man)

A horn that just goes click will often respond to a tweak of the adjuster but if it took out the other horn too then you may need to check the quality of your wiring.

Hi

Before you do anything, check the EARTH. A poor Earth connection will degrade any Voltage / current. Radio aerials too where replaced often when they only needed the earthing remaking and a light coat of "Vaseline" to reduce the chance of it happening again!.

Ah yes, the Land Rover drivers horn of choice !

Mine has got some air horns on (Fitted by a previous owner) - first time I tried them I had a heart attack!

Look like Halfords specials from the 90's

I had the (air) ones, nearly 2ft long on the roof of an American Motorhome they played "Dixie". Not legal on the road though! (switchable). Had Air horns on the BMW Bike too. Often Needed them, to wake up sleeping drivers!. (Sorry mate, didn't see you!).

I had a klaxon until some low life nicked it. Didn't even undo the bolts, just sawed it off its mounts.

When my brother owned my Spitfire, it had air horns fitted. One evening, as he was driving along Oxfordshire country lanes towards mum's house, there was a loud BANG! followed by a constant death rattle. He pulled over, stopped the engine and popped the bonnet but, as it was night time and pitch black in the middle of nowhere, he couldn't see a thing. He walked the remaining two miles to mum's, borrowed mum's car, drove back and towed the Spitfire in. But in the time it took him to do that, some scumbag had smashed the driver's window with a block of wood that had been in the unlocked boot.

The next day, we had a look under the bonnet and the cause of the bang and the death rattle became obvious. The compressor for the air horns had fallen off its mount, swung across on the plumbing, and smacked into the fan.

The Herald has a large Lucas horn, sounds more like a foghorn. Very loud.

got Colonel Bogies on one car, was a life long dream 30 years ago... :-)

those steibel ones look good.

I did an article in the Aug 2015 Courier re the horns that may be of use.

I have also attached a rough sketch of the wiring layout. This is for the Vitesse. Please note the Herald and very early Vitesse, 1962/3, does not have a fuse but otherwise is the same.
