Ok so my horn is not working. I've bridged 87 and 30 on relay K2 and nothing works. I then put the relay back and it is clicking when I press the horn button.
Would this indicate that the horns are faulty?

It indicates that the fault is at the horn end of things, and that there is no problem with the horn pushes or wiring to the fusebox.
If this was a four pot E30, I'd bet on the horn being faulty, but you should have two of them, and it's unlikely they've both failed at exactly the same time. Or was it down to one before?
Check fuse 7.

Can you pull the wires off the back of the horn and put a test lamp across it to see if it lights up when the horn button is pressed ?

At least this would tell you if there is power getting to the horn itself.

I have at least 1 horn in my parts stash if you need one

Yes fuse 7 is fine so I'm assuming it is both horns. Thanks for the advise!

Fixed! Took the horns off to have a look; I'd tightened the small screw to tight which controls the tone. Also I didn't realise that each horn has 'L' for Low and 'H' for high tones - unless these are not OE.

Hmm pukar, you could have at least given a page number - but no matter I'm on the case. I'm on page 10 of 57 and still looking for the required advice. I'll persevere! :P winkeye
