LED Headlight on a 68 Wide Case Scrambler

[Zoomersmoto]

It took me a dictionary, a translating machine on the web and a joyful while to translate all your idioms
Seems the Hessians, where I live in southern district (Hesse is a state in the heart of Germany https://en.wikipedia.org/wiki/Hesse), are as curious as the Texans.



Hence, I continued researching about Ducati singles alternators, and finally found this:



Here we see the sketch of a stator with the usual 3 output wires, but 2 internal ground connections of windings. It must contain a special winding scheme, as well as at least one coil in dual-layer fashion. OK, it should belong to n/c models, but your early SCR might have this type anyhow, so measuring 3 certain resistances against the stator is a matter of course in that case. I feel unable to answer your question about resistance values measured as long as we have not perfectly identified the type of stator in your bike. Let's unravel that mytery!

Don't be afraid of beeing misjudged - seems your brain sits in the right place And btw, some important info about Hessians, maybe unknown in the US: https://en.wikipedia.org/wiki/Hessian_cuisine

Most don’t know this but curiosity didn’t kill the cat but digging deeper into that idiom reveals that it actually had another meaning...worry not curiosity was the killer of the feminine feline’s mystique but satisfaction brought it back! Nothing more satisfying finding the answer to a riddle. Like that idiom so goes the wiring diagrams of the ducati scramber. We need to keep digging.

Now we are big fans of a German bloke named Walter Kaaden, brautwurst, and sauerkraut! While I am working on the Ducati my son Zeke is getting ready to dive into expanding his knowledge of harmonic resonance and wants to build his Bultaco 360 into either a drag bike or a hypermotard. We do know how to start them backwards! https://youtu.be/2r3Pfx0WCkI

Now back to the topic at hand. We have wired the Ducati similar to the original diagram as follows:

Yellow wire runs the ignition
Red wire runs the the LED headlight via a bridge rectifier
White wire goes through a 6volt reg/rectifier to charge the battery. Plan on having the battery wires to the horn.



I know you think seeing is believing and we will get there but we have discovered many things that we shouldn’t have by being curious as a cat!

Will post a diagram later!

Cheers

Very interesting, thanks.

For the moment:
It's Bratwurst https://en.wikipedia.org/wiki/Bratwurst, not Brautwurst. "Braut" means bride. I suppose you will never squeeze your lady into a blender or meat grinder and convert her to a disdainful wurst

Walter Kaaden of course is well known as a 2stroke wizard. His work partly was based on that fundamentals found by Hermann von Helmholtz https://en.wikipedia.org/wiki/Bratwurst, who sort of " invented" the acoustic resonator.

And here is another nice and practical application of a resonant tube ( sound amplifier) http://www.logosfoundation.org/scores_gwr/singbikes.html

cheers Hans

p.s. congratulations - your son seems to be an etraordinarily gifted youngster

Hans,
Please forgive me, for my favorite English author GK Chesterton, the Mark Twain of Britain, once said, “even a bad shot is dignified in a duel.” That sausage pun was definitely a bad shot! However my wife is Scotch, Irish, Cherokee, and Apache which may qualify as Brautwurst. She will tell you her wurst is the best! A powerful paradox indeed. She once said about marriage, “many make a vow for better or worse but nobody knows what for worse is until you are in it.” There you go Brautwurst!

Now to the current mental facilities and gifted-mess of Zeke DeZeeuw. You may change your mind after seeing this! https://youtu.be/T7mIxUj6zBI

I think he is half of bubble shy of level myself. He will tell you the nut doesn’t fall far from the tree.

Please forgive me for reinforcing the stereotype of us Texas being bass ackwards but I hope you tell your Hessian friends that you have seen a Texan ride a Spanish horse in reverse. Do you know what a Texan says riding his horse in reverse? Wah eey!


Also looks like we got the lights figured out on Delinda the Ducati!

As much as I like cheeky "banter" as anyone, I find it really tiresome trying to read through it to obtain decent info.

I guess I'll probably get flamed but can you take it elsewhere.?

Thanks.
Veilen danke.

Sure. I appreciate straight shooters. This is more straightforward. One of our failures. Do you know why it doesn’t work?

Here is the wiring diagram we are using for the LED headlight conversion on a 68 Ducati 250 Scrambler per the original wire colors on the 28 W 6 volt magneto alternator. We are using a modern 6v regulator rectifier in lieu of the original diode for the battery circuit. The pink wire on the REG REC is not connected. Just for y’alls information purposes our Duc started easily on both the yellow and the red circuits. We now understand why the Yellow circuit is the ignition because it is the pulse coil that is in harmony with the magnet and timing of the machine for ease of starting. (Per other motoscrubs posts.) This bike starts as easily as our other bikes that have electronic ignition on them. If you see something wrong with our diagram please feel free to call me out on the carpet. If you think you can’t handle the bantering in these posts then your dog probably doesn’t want to hunt IMHO and don’t even attempt to cull the archives of DewCatTea Bob bless his soul, punctuation, and the proper modified use of the English language !:)!

Little update. So we burned the LED headlight up because we didn’t have a regulator. So we will install a modern REGREC next time. So for the time being we have gone back to the standard lamp. Also we have installed the battery, horn, and tail light on the white wire circuit. We used a toggle switch under the seat, 6v reg/rec, Wago connectors in lieu of the Vintage Ducati connectors.
