Looking to locate K63.

Fuse17 blown and replacement glowed and blew (~3s).  No horn everything else seems okay. Alarm horn works (think this is a different device).

If Mr Haynes is right and if I've read it right, circuit could be; anyone care to verify?

FV6  feeding F17

F17 feeding   a) K63 relay coil   and   b) horns H18/H48/H2 (are there three?)

K63 coil to   a) S64(a)    and    U28 to S64(b)

S64(a) and S64(b) to earth - sorry, must call it 0v.

Horns to relay contact (NO) to 0v

Where is K63 hiding
What/where is U28 - not listed in my lie book.
Anyone other ideas/previous faults they care to share.
Is K63 the same as anything else I can swap with to prove/eliminate - when found.

-2.5L minifacelift.

As its not in the engine compartment ..

I'm guessing it must be one of the fuse box ones ...  I'll do a little searching ...

[dbug]

I had this - turned out to be a faulty horn!!

[star_whites]

What year is the car??

[JohnM]

R reg - 98?

What ought to matter is; 2.5L petrol mini-facelift. Elite. Steering controls for stereo, full ECC, windows in the doors (switches). 'letric everything (except horn!).

Confession mode>
Not been out to check anything since Sunday
/CM
- but not feeling guilty yet as there is noticable lack of ideas so far.
Okay, must check horn connections are intact but anyone spotted K63?  

[JohnM]

Thanks dbug - 400Hz horn faulty.

Never did find the relay though, anybody know it's hideout?

is that correct?  I have a feeling my alarm horn is not working (power sounder is - just), but the normal horn off the steering wheel works fine.

Yep, seperate. Sits next to the power sounder.

is there a specific fuse/relay that drives it?

[Marks DTM Calib]

Nope, live side is connected to the 80A fuse by the battery and the low side is actuated by the central locking/anti theft ECU.

[ians]

Ah - so most likely the horn is goosed then..

Ah yes, must have had my eyes shut!
