k1200s horn - c'est mort?

Press button, no sound is emitted. Don't recall when it last worked but
it would precede when I fitted my Tomtom...

However the wiring was already in place for my previous garmin
Streetpilot so fitting the TT was simply a case of unscrewing a block
connector (one end of the BMW accessory lead) to remove the Garmin wires
and poke in the TT wires and do the screws up again.

There was a lot of spare wire with the TT (the battery and accesory lead
are inside the (obviously fake) fuel tank) and I just coiled it up and
shoved it into the space between the battery and the headstock - a snug
fit - am wondering whether pushing these wires in may have dislodged a
connecor for the horn but, removing all the TT wiring today to have a
closer look, there appears to be little chance of that.

Looked for the fuse box to see if that was the issue - then discovered
there are no fuses, only circuit breakers that should reset themselves
automatically.

Before removing the fairing to get access to the horn I am seeking any
suggestions for any obvious things to check.

All other electrical items are working (and TT!).

 

Is the horn directly connected to the switch or via the CCB[1].

If the former then diagnosis should be fairly simple. If the latter: good
luck.

Haven't the foggiest. MOT time soon too.

 

Horn's are over rated.

I've just ridden from Baton Rouge to Buenos Aeries without one

 

A convertible (top-down) 3 series pulled across my path on a roundabout
near Farnham on Sunday - to let him know I was there I simply blipped
the throttle with a little agression - which elicited an apology.

So yeah, horn's (sic) are overrated.

 

Called the BMW dealer for some advice. They can diagnose but suspect
it's going to be faulty left hand switch unit - an eye-watering £150 +
fitting.

 

I've got a 9v pushbike horn on the Fantic. Cost a few quid & is good
enough for MOTs.

 

Just fit a Stebel Nautilus on it via a relay. £20, job done.

That's if the horn switch is still operational. Have you dived in
there with a multimeter to check ?

The advice from the BMW garage (and I understand there could be a
commercial motiviation for this..) was not to atttempt any form of
dismantling of the switch unit.

 

That's probably due to a) the massive over-complexity and b) the only
way in is with a hammer and bolster, leading to c) massive fallout of
pingfuckits at speed.

 

I understand that, but putting a multimeter probe on the horn contact
at the horn end whilst pressing the horn switch won't need the
dismantling of anything ..

Paul.

 

I have employed the move along side and shout "BEEEEEEP" through the
window technique.

 

I take it from the lack of response you want me to pop over any put /
my/ multimeter on it then

Paul.

 

I use that same technique on foot in crowded stores.

Well I have a Tiger screen in the garage awaiting your attention...

 

Fair enough, not sure if I have a current number for you, but I can
pop over sometime this w/e.

How you fixed Sunday early evening ?

Paul.

 

Heh. Multimeter - current number. Heh.

 

Well, it was close but no cigar (you probably heard be ride past at
6pm ish)

Send me your address again, eh. [1]

Ta,

Paul.

[1] It's saved in the zymurgy account, but since AOL took it over, the
search facility on my zymurgy account has been bollxd. Best to mail it
to the hotmail account I use for the French runs ..

 

Didn't see this, actually was enjoying the roads of Wales this weekend -
fantastic weather for being out on the bike.

 

You can email me on gmail account in the headers.

My number is the new one I got in 1997.
