I am doing ac to dc conversion on Yamaha Vino 125... did I do it right? Here's the before (got it off from internet) and after (on my scooter) photos   |

 Mic, your videos are legendary, I have picked up a lot from them for those that have never seen them www.youtube.com/c/micbergsma/playlists. That is if you are the same MicBergsma? Sorry I can't answer your question but there are several smarty pants scooter guys here that can.

 Very cool if it is the same Mic. I've done a few now, but I'm not a pro so I still have to look my own stuff over carefully to be sure I'm correct. It looks like you've got the idea, but just to be sure, this is what you're after.  Basically you are setting it up so that each end of the charging/lighting coil is connected to one of the wires (yellow or white) and no longer grounded.

Once you are done you will need to direct the yellow and white wires to two legs of a three phase regulator.

Hey! Thank you so much! Yes haha it's me MicBergsma (Mitch Bergsma) I made a new channel called "Mitch's Scooter Stuff" in 2013 and started posting only scooters videos there, not sure if you knew about it   Mic, your videos are legendary, I have picked up a lot from them for those that have never seen them www.youtube.com/c/micbergsma/playlists.

Hey Brent, how are you doing!! Thank you so much for the info! After looking at your cool custom wire diagram, I love it! That helps a lot about red/yellow wire from TT's rectifier ... I have the same one too... I connected it to the blue wire and nothing going on and I realized that I need to disconnect the blue wire that tapped into stator's yellow wire from headlight switch so then connect TT rectifier's red/yellow wire to blue wire to headlight switch... that sounds right... Here's my drawing on Vino 125 wire diagram...  ![]()  Very cool if it is the same Mic.

Yeah, lighting needs to have it's power source from the regulator's red/yel to use it's relay. You don't have to use that, but it's a cool feature. I really like it because, aside from being an easy way to convert to battery powered lights, it makes the scooter feel more modern with the delay after shutdown and not coming on till it senses that the engine is rotating. I don't tie anything into the wires from the stator and put everything either on the relay (r/y) circuit or connected it to battery power or ignition switched power to make full use of stable DC power. I think I would connect both of the wires that you have in blue to the reg/rec's red/yel. I'm about half asleep ATM, but I think that should let anything that relied on stator output before now run off of the relay.

I will have to study the wiring but a quick look seems something is wrong. It is 6:30AM and I am sleepy.

The CDI is #11
The stator is #2
The RR is #3
Both the blue wires should be disconnected from the lighting circuit output to RR and relocated.
I'm not sure what the red hash marks on the lighting circuit annotate but the W Y/R wires are now equal legs between stator and RR
The RR must be replaced. It and the stator have to match.
You now need a single phase, full wave RR
When your changing circuits around, especially the high current headlight circuit, you need to consider whether the wiring and switching will handle it.

Once you are done you will need to direct the yellow and white wires to two legs of a three phase regulator. Floating the ground has absolutely nothing to do with a three phase RR. It is done to convert a single phase half-wave to a SINGLE phase full wave system. A single phase full-wave RR is needed |

A three phase regulator rectifier is more commonly available, used on larger scoots. It is not necessary to use all three AC inputs, two are quite sufficient for the rectifier stage. If you can find a single phase full wave RR that is readily available, by all means use it. |

Oh man I just realized that I didn't mention the name of RR I have ... all I typed was TT, my bad... it's Trail Tech (7004-RR150) already installed on... let me grab the photo

Ok, I just disconnected two blue wires that goes to headlight switch and speedometer lights... and connected with trail tech rectifier's red/yellow wire.... turned key on, the headlight LED bulb and speedometer didn't light up but tailight (dc side) did light up... same like original... so I am not sure what I need to fix ugh  |

Well, you said you turned the key on. Did you crank the engine over or attempt to start it? That Trail Tech's relay should sense engine RPM, or basically just voltage when the engine rotates. So, when I had that reg/rec on my scoot, I could turn the key on and my lights did not come on. When I kicked the engine over, even if it didn't start, the lights would then turn on. As I mentioned earlier, it also has a delay for shutdown. When you turn the key off, the lights connected to that relay output will stay on for a few seconds. There should be a dial to change the time or I think eliminate that altogether, but I believe it always needs to sense voltage in order to trigger that relay to turn lights on.
So, short answer is try cranking it over first. Even if you aren't confident about starting yet, disable spark and kick it over and see if that does it.
If that doesn't work, then unfortunately you may have to get into some wiring.

Mic, your videos are legendary, I have picked up a lot from them for those that have never seen them 
Very cool if it is the same Mic.
