I wanted to share a wiring diagram I made for this specific bike US version 1975 (but was actually made in 1974). I made it to teach myself the electrics of a bike and I thought it might be helpful for others. The year of the bike is important because, according to 66Sprint, the little green tail ground from the solenoid to the battery negative is an arrangement used until this specific solenoid's inventory was used up before switching to a different solenoid.

I'm uploading an image of the overall diagram as well as a PDF of the colors separated into separate images. I did this so it's easier to focus how each component is connected through the wires' colors. A high resolution of the overall diagram is also in the PDF.

The wiring diagram is an update from the one found specifically in the owner's manual—it is more detailed than the one found in the shop manual or the Clymer's manual.

The components are updated to the following with some notes:


  • regulator/rectifier combo unit (the Yellow and White Yellow from the stator is merged into one Yellow wire. Wiring for old regulator edited.)


  • 2 prong flasher relay for LED lights (the Black of the relay is the load side according to this specific model so it plugs into the Grey wire. not the harness Black as you might think!)


  • LED turn signal indicator light in tachometer (a non-polarization bulb was used so a diode is not needed to prevent back flow over the turn signal circuits. Avoids flashing-lights-all-the-time syndrome.


  • LED lights for all bulbs except for headlight (headlight was updated to a H4 bulb using the stock lens. Hack was made following TStephenGaunt's retrofitting post from the old forum)


  • Points and Condenser taken out and replaced with Charlie's Place electric ignition.

If there are any mistakes found, please let me know and I'll update the diagram.

Hope this helps!

Awesome.
Also, forgot to ask in initial post:

What do the abbreviations KB and KW stand for in the ignition switch?
 
I think you mean "in the right handlebar switch" - and though I do not have the legend of the original in front of me, based on the diagram of the switch assembly it's the kill switch and the KW seems to apply to the black with white wire that goes to the coil after the other side of the switch is fed 12v power at the KB, which likely refers to kill switch black 12v switched power

Missed that part… he sure left a good resource in that diagram, I could actually read it. [emoji849]

She, actually... and you probably have stickers she designed for us (if you have version 2.0). And the part in bold might confirm what I've thought for a while, even with someone who is active in many threads - that it's easy to not see some stuff when not using a computer to view the forum.

Cool, I have a “Snicks original “.
FYI: I can see the date of her last post in this thread… #6 on 7/14/20 ( just didn’t pay attention).I can’t see the last time she was active unless I click on her user name and look through her posts and check dates.

Actually, and I guess I should create a tutorial on some of this stuff (for those who'd care, as many only focus on their own involvement), you can go to their profile to see when they were here last. Of course, no one has to do that with me because I'm always here.

I’m not usually at the computer unless I’m paying bills, but I’ll use it to get on VHT to sort my summer rebuild threads with pics one of these days… maybe before I forget what I did! I am aware there is much more info available on the PC version.

Great and readable diagram.
Very much appreciate the effort put into this. Thanks!
 
Nice job, I enjoyed it the first time around. Just re reading it this evening, was intrigued by this:

  • LED turn signal indicator light in tachometer (a non-polarization bulb was used so a diode is not needed to prevent back flow over the turn signal circuits. Avoids flashing-lights-all-the-time syndrome.

What is a non-polarization bulb ? Is this some kind of LED lamp that I've never heard of ? If so, certainly seems an easier solution than soldering two diodes into the feed wires and running a separate ground wire.
