so I have rigged up some awful chrome signals to keep 'er legal without the fairing. I inserted the original fixtures and bulbs into the housings, cleanly as far as I could tell. Everything worked great, both signals working, etc.

then I had to charge the battery so I disconnected it so as not to fry the electrics. I also cleaned up the throttle gears, and so had to remove the switch housing on the right side.

now neither signal does anything, I don't hear any relays, nothing. Also the horns are out. I tried replacing the #3 down 15 amp fuse with no help. Any suggestions? I don't have an extra flasher relay to swap out, so I'd like to try other things first...

I guess opening up the housings and making sure nothing has shorted out is a good step, replacing all the fuses may help, but any obvious known issues would be appreciated!!

Thanks!!

Check the number 7 fuse. That is switched power to the flasher relay, horn, radiator, fan (via the temp relay) and alarm connector(green/brown wire). The number 3 fuse is unswitched power to the flasher relay and LCD clock..

It could be that your fan is causing the problem. If the 7 fuse is blowing then try disconnecting the fan (violet/yellow and brown connector under left side of tank) and see if the fuse stops blowing.

awesome! That was totally it!! Thank you!! I had seen someone mention 7 in another thread but I appreciate the corroboration :-)

So just in case anyone else is reading, is there an adjustment on the Fiamm horn, perhaps under the sealant? One sounds like a sick calf instead of the blast I remember from my other K100!!

Make sure that the quieter horn is mounted using the two thin strips of metal. Try to mount them solid and they don't make much of a noise.
Not sure you can adjust them.

so I actually have two Fiamm 35717 horns, both AM 80, and I can't tell that one is different than the other.

There is a screw covered by a silicon sealant, I will see if that makes any difference.

But what were the OEM horns for our bikes? My 88 LT has a set of horns that not only cleared the road, but made me jump when I honked!! affraid

I was the one pushing the button, but no matter, I couldn't keep myself from jumping!!! bounce

G'day Snowbeard , I had a similar problem with my bike , the fan had siezed solid so I had to get a new one , the new fan was very stiff so when it was time for it to operate it was drawing too much current to start turning & blew number 7 fuse killing indicators & horns

Parts 61331371914 and 61337163975.

The reason that they sound like car horns is that they are the same horns that BMW installed in cars of the era.

cool, no cheap ones on ebay, but I'll keep an eye out!

Funny, I did sit chatting with a neighbor the other day and saw the overheat light come on but no fan... maybe that is when it blew! It was fully blown too, just two stubs, not even pretending to look good... better check on that fan, but winter in Colorado I probably don't have to worry too much!! Summer in Lisbon was killer on the heat tho, one time the coolant (filled in Scotland) pissed up my leg when it overflowed out the nipple!!! Shocked

it just kept spraying like a boy baby until it leveled out and never did it again...

You can buy just the fan motor, they aren't difficult to change.

so I had done nothing to it when that happened. I read that its good to spin them by hand to get them going, and so I did lately. It was stiff, not freely spinning, but did rotate. Is that a bad sign, or should I just wait and see if it starts up when needed next?

When you feel how a new one spins, you'll know how screwed the old one was. I've had mine boil all over my legs as well, that's how I knew my fan wasn't working.

If it is anything except very free to spin then it is trouble. It will overheat and melt the brush holders or as for you just blow fuses.
