A thought occurs to me: maybe the mod has more to do with the starter circuit than the lighting. The V11 is prone to what is often referred to as "startus interruptus", i.e. when one presses the starter button, one is rewarded only with a click from the solenoid on the starter motor. The cause is insufficient power to the solenoid to pull it in properly. This is a problem that not only the V11 models suffer from. The common solution is to feed the starter solenoid directly from the battery, i.e. the power feed to the starter relay and from there to the starter solenoid, which is switched by the starter switch, directly from the battery. That is how I solved the problem on my Breva 750 i.e., but it is not that simple on a V11. The starter relay is of the type that has both a normally closed and a normally open contact. In the "resting" position, the normally closed contact feeds power from the ignition switch to the lighting relay, thus holding the lighting relay closed, i.e. "switched on", thereby feeding power through from the battery to the headlight. In the "switched on" position, the normally open contact of the starter relay is now closed, thereby taking the power away from the lighting relay (good plan, the lights go off when the starter is engaged) and feeding it instead to the starter motor. This means, if one were to feed the power to the starter relay directly from the battery, the lights would be one all the time because the starter relay feeds the power to the lighting relay in its "resting" position. Therefore, in order to supply the starter solenoid with power directly from the battery, it is necessary to add another relay for this purpose. There are some threads here on the subject, which one might be able to find by searching "sixth relay" or something like that. So, to cut to the chase, maybe someone has done that modification and mounted the additional relay up near the headlight. I would have tried to integrate it into the row of original relays, not hard with the right parts, but not everyone is as much of a perfectionist as me.

That should be true, I think, but the headlight relay should get the power directly from the battery. Look (again) at the diagram I posted here. It is allegedly for the models from 2001 - 2003, so it should be right for a Tenni, I think. Anyway, regarding this: The first two, yes, that appears to be a photo of the headlight shell, and it is upside down. I reckon that it is a fair assumption that someone has modified the wiring and added a further relay. There is nothing like that construction behind the headlight of my 2002 Le Mans, which I believe should be electrically the same as a Tenni. Also, the green and red wires in the picture seem to be thicker than any I have seen in that area of mine, and the spade connectors with the blue boots are, as you commented @Weegie, not original. I'd say someone's been at it, and @Tennitragic probably has no option other than to follow the wires and find out what's been done.

For what it is worth, here is the result of that. The wiring diagram is on page 459 of this PDF, according to the document viewer https://guzzitek.org/gb/ma_us_uk/1100/V11_1999-2003_Atelier(Compil-GB-D-NL).pdf The legend is on the following page. Here is what I got. Maybe it will help someone.

I found the home page of the channel. Looks to be pretty much bullshit, unfortunately. https://www.youtube.com/@MotoMagzYT

Or they haven't got "caught" yet. Good point though, it might indeed be a commisioned "public opinion test".

Yes. And don't forget, it might be not just one problem. If two different lights are not working, the problem might be common to both, but it might also be, for instance, a bad connection at two different places. As you say, get out the voltmeter and go looking for where the volts disappear.

I just found this on the Tube. Does anyone happen to know who is behind it? I can't imagine, really, that it is official. Looks nice, though.

My thoughts exactly.

I don't think they do. I've just spent an hour or so with a printed copy of the wiring diagram and coloured pens, and it looks like both high beam and low beam get their power, switched either-or at the switch block on the handlebar, from the lighting relay. The lighting relay feeds through power from the battery, and is itself switched from the normally closed contact of the relay that switches the starter motor with its normally open contact. The running lights (parking lights) get their power directly from the ignition switch, in common, but via a seperate fuse, with the blinkers, i.e. from a different source as the headlight itself. That may be the source of your memory.

Yes. It is involved in the switching of the lights, so it could be the cause of the problem. Don't exclude anything as the cause of your problem until you know for sure it is not. That kind of weird bollocks is sometimes due to a bad "earth" connection somewhere. The volts can't get through the circuit they are supposed to be taking and find a way somewhere else, sometimes even apparently "upstream". I think you might be going to have to look at the wiring diagrans (or manually trace the wires) and systematically check all the connections, switches, relays, whatever involved in the lighting circuit. And as already implied, don't forget to check the circuits all the way back to the battery, i.e. also on the "earth" side.

Yes, I am familier with the puzzlement. Apparently there are women in the USA whose first name is Taylor. Where I come from, that is exclusively a surname. I believe I have also heard of women called Kennedy. That is a surname. Mine, for instance. Still, not quite as "exotic" as Moon Unit or Dweezil.

I had a Kawasaki 1000 GTR for about 10 years. Two, actually. I crashed the first one and bought another one to replace it. Not a "cruiser" in the sense that some Harleys are, but a barn-door fairing and luggage. Even so, more of a "sport tourer". Anyway, it went very well, handled nicely, and was lots of fun. I only got rid of it because I didn't have the need for something like that anymore. I bought it to be able to do long Autobahn trips with luggage for two weeks on a job, and that doesn't happen any more. As far as the wobbles goes, as I indicated further up, the worst thing is lots of traffic on a freeway. The turbulence hits the big fairing, and the bike reacts to it. It took me a while to get to the point where I could just ride through it. Further up was also mentioned a custom build bagger. That is where I see the greatest potential for instability. Bolting panniers onto a bike that wasn't meant to have them, maybe dicking aroung with the fork length and whatever. That can work out well, or not.

You, and the horse you rode in on.

Have you tried comparing the part numbers? With fairings and such it can be a little confusing, because different colours have different part numbers. The stuff "under the skin" generally has the same number if it is the same part. It looks like you can get the parts lists that are relevant to you here (scroll down to 1000 and 1100) https://guzzitek.org/f/parts_list_f.htm#gb

Thanks for those pictures, and the report. I've got a plate here waiting to go in. Hope I can get on to it (and the other pending tasks) towards the end of winter when it is a little bit warmer in the unheated garage / workshop.

Luggage can cause the wobble. Particularly on a freeway with a lot of traffic, i.e. turbulence.

Now that I think about it, it probably works for a lot of German names, too.

I don't have one, either generation, but... In the German forum that I am active in, a number have bought the new Stelvio, and they all seem very happy. One in particular I know for sure had the older generation, bought a Mandello first, and swapped it for a new Stelvio. He is a fairly big bloke, about 2 metres tall, and his wife is not much shorter. They love the new one.

What happens in the film, @Lucky Phil ? Youtube wants me to register to see it, R-rated or something, and that's not going to happen. But I'm curious...

Yes, I have that. On top of that, I think my syntax has been affected by thinking in German all the time. A friend in Melbourne commented on that after only 4 or 5 years here. It's nearly 30 years now, and I notice the effect myself sometimes when I speak English. I don't believe, however, that my accent has been affected by speaking German all the time. I know it can happen though. Some years ago, my mother put me on the telephone with a woman she knew who came from Bavaria, but had been in Australia for about 50 years. She spoke German with me on the phone, but even I could hear that her German had acquired an Australian accent. I think that people are different in that respect. Some acquire an accent, deliberately or unconciously, very quickly, some don't. Mine is Michael. I don't think that is an indication. It seems to be fairly perennial.

An Australian accent, of course. I reckon most Germans can hear that I am not a native German speaker. Funnily enough, when I have spoken about it with various people, the most common guess is that I am from the Netherlands. Having paid attention to the way Dutch speaker sound when speaking German, I can understand that. There really are similarities to my accent. There are not many Australians here, so most Germans have never conciously heard an Australian speaking German. On the other hand, most Germans have conciously heard Dutch speakers speaking German, so they go for the familiar "best guess". I still chuckle though, because I know my Australian accent is pretty obvious to those who are familiar with it. And that isn't going to change. I speak and write very servicable German, but I am Australian, and I am quite content with that being obvious. Incidentally, when I speak English with my family, and certain friends, my Australian accent is also very obvious. But given that Australian English is the only variety of Eglish in the world that has remained pure and unadulterated, that's ok.
