Berlingo Horns

[Rasputin]

When I was a kid my uncle had a PA horn mounted on his car roof and a mike a bit like a CB PTT one (maybe it was one). He had great fun telling other drivers very audibly what he thought of them!

I love the deep truck horn sound. My horn goes toot toot and it sounds pathetic. I've had my eye on a Stebel for a while. You can use the existing connections to the horn, parallel off them to drive a relay coil, then for the output contacts just run a fused supply off the main engine bay supply / battery / piggyback at 20A to one of the output contacts, and the other output contact to the Stebel then return the new horn negative to a good ground. If you want to switch out the beefy one, just run the negative from a ground inside  the cab through a switch and out to the new horn negative.

That way you only pass a ground wire through the bulkhead and if it ever chafes, the horn will still work and it's super safe.

I'd have to draw that to see whats what.

I didn't realise that Stebel did so many different type!

Had a quick look for my horn late yesterday, i know it's at the front left somewhere but dammed if i can find it.

Down the front on the driver's side, behind the bumper bar in the engine bay I'm sure.

I'll draw a circuit on my schematic CAD system once I get to work today and post it up as a PDF for you.

All horn circuits are switched-ground, so it would work really well that way and let you have OEM horn, or both together.

Cheers for that, look forward to it.

Here you go mate:

The relay (marked U) has 2 pins for the 12V DC coil and 2 or more pins which are normally open contacts (marked N/O) - those close when the coil is powered.

You can get a simple relay with a 12V DC coil and only one pair of N/O contacts rated at 20A DC switching.

I didn't edit the relay component pins to mark them N/O hence the description to make it clear. If the one you get is a changeover relay, it will have a pin marked COM and two pins marked N/O & N/C - use the COM and N/O pair.

Cheers for that Zion, printed off for when i get the horn.

Oooh - suits you Sir!

[Rasputin]

Ah, but does one route the loom to the left or to the right, Sir?

[Zion]

OOh routed on the right Sir? Is it?
