New horn

[mike202]

My OG horn stopped working. I am getting 12 volts across the terminals so it’s Kaput.
I have bought a new Hella one from JK. My question is that the old one looks as though it’s inside a case, do I need to remove this case and put the new one in it ?

No, the new one just bolts on as it is.

As above.

That said, the old type are often rebuildable. Just unscrew the face, clean up the contacts and you might be able to persuade it to live once more

Thanks guys.

I let the screws holding the face on soak overnight in wd 40 and took it apart today. I thought I would have to cut them off by the look of them, but I think underseal has protected them from becoming too rusty.
It looked clean inside but dirty around the rim.

Wiped it all clean and tested it with a spare battery and would you believe it - it works again!

It sounds a bit of a lower note compared to the new Hella one. Probably because it is a slightly bigger diameter.
Bit of a dilemma now- do I put the old one back on or just fit the new one [emoji38][emoji38]

Old one - as above, keep the new one for if it ever does give up the ghost for good.

 

[mike202]

Old one it is then!

Great stuff

From memory, you can adjust the note on some of them. But I might be mistaken.

Yes, you can by adjusting the centre nut on some older horns.
