I'm in the middle of doing the DC>AC conversion to get rid of the battery which has been the bane of my smallframe-owning experience. I'm following the same process as done in the Scooterwest video , my wiring setup seems to be different from the example in the video and I'm struggling with how these should be split up and connected to the two 6V regulators. This is the setup coming out of my wiring loom. The two yellows match up to the scooterwest instructions, but instead of a third white wire with red markings, I've got these two other wires, pink and purple: And the wires that originally went into the fusebox (only housed a single tube fuse) and then to the positive terminal of the battery are these two, combined into one connector: and finally, here's what my regulator looked like originally before disconnecting everything. Based on this, I believe the two yellow wires go to the first terminal of each regulator, but then what about those pink and purple wires? Also there doesn't appear to be any white/red wire as noted in the scooterwest video. Any advice/assistance is greatly appreciated! (sorry for the huge images in the last two pics!)

A few questions:
- Does the scoot have signals?
- 6v battery?
- How many fuses?
- Does the sound of the horn vary with engine speed?

Also:
How many wires and what colours at the ignition switch?

Hey thanks for the reply! Here are the answers to your questions: - It does have indicators, but I have removed them. The wiring for them is still in place though. I am not looking to reconnect them. - Yes, 6V battery (which I am looking to remove) - Seems to be just one tube-style fuse. Housed in this junction box: - The horn kinda always sounded like sh*t so I can't say that I really noticed any big difference at various engine speeds. - Here's the wiring at the ignition switch: Any help is greatly appreciated!

Can you show me a photo of the wires coming out of the stator, and a photo of the wires connecting on the junction box. I think I have it figured out now but I want to be sure about the wire colours before giving you directions.

Here's the junction box: I don't know if i'm ready to start pulling the engine apart to get to the stator...

Hard to tell.
Hmm, remove the wires from the regulator. Use a continuity/ohm meter to see whether the purple or the pink wire is connected to the two yellows.

OK, bit of an update and I think I've made a breakthrough. Turns out the purple wire that was plugged to the original regulator just went a short distance over to the flasher unit. And the pink wire that was plugged to the original regulator is the same pink wire that is tied in with the main red power wire pre-fuse-box. So neither of those are associated with the two yellows. So now I have the following: the loom that comes into the battery compartment houses 6 wires: The main power (red), a black ground, the two yellows from the coils, a white and a white/green that go to the flasher unit. I know that I connect the two black ground terminals to the two new regulators, the yellows to one terminal each of the new regulators, and the main power (red) to one of the new regulator terminals. That leaves me with 3 terminal connections, but there are 4 terminals between the two regulators. And I don't seem to have the white/red wire referenced in the video to ground. I'm also not planning to connect/use the indicators, so do I even need to tie in the flasher unit somehow? From the video it seems that there's supposed to be one wire for the headlight and one wire for the taillight/brake/horn. Are both of these somehow combined into that single red wire? This thing is also tied to the flasher unit by a single wire and I have no idea what it is or what it does. Any clues?

This is the diagram that looks the closest to what you have: scooterhelp.com/electrics/wiring/VMA2_V9A.wblink.pdfAs mentioned in the video, the yellows go to two linked coils that have a centre tap rather than a ground. Unfortunately I can't tell which wire is the centre tap by looking at your pictures. Someone is going to have to test the wires to figure that out. Sorry but that is the best I can do "over-the-phone".

The "thing" is an aftermarket audible warning for when the signals are on. Doubt it will work on AC. Neither will your flasher relay. Have top change to an AC flasher relay if you are going to keep the signals.

The only wires coming in that don’t go to the flasher unit are the red wire and the two yellows. I’ve already removed the indicators, so I’m not trying to reconnect them anyway.

OK, I guess I've narrowed it down to basically these two options: Version 1: I've got the one main power red cord (I believe this wire is typically green) going to one terminal on one of the regulators, and the yellows going to one each of the regulators, the ground terminals are grounded, and the two grounds from the main loom are also grounded. This leaves one empty terminal on the 2nd regulator. Not sure if that's bad or not. The green and green/white that just go directly to the flasher unit can be tied off. Version 2 is the same as Version 1, but here I've connected the purple wire that feeds from the flasher unit to the 2nd regulator (it was originally plugged into the original regulator). I'm not sure what this version really gets me since I've already removed the indicators anyway. But at least now all terminals of the regulators are attached to something. Is that something that's actually necessary? I don't know

Go to your local hardware store and buy a cheap multimeter.

So I went ahead and pulled the trigger on the latter wiring setup posted above. Bike starts right up first kick and the headlight is commensurate with the throttle. Fairly dim at idle, brighter as the RPMs increase. However, the tail light is completely out, no matter the RPMs. The brake pedal does nothing either. Normally I would think this might be a bulb issue, but before I embarked on this battery-removal project a few weeks ago, the tail light worked with the battery. I’ve removed the connections and cleaned them but still no dice. Any suggestions?

Swap the yellow wires and see what works then.

Yesterday I continued to work on the bike and figuring out exactly where each wire goes. I found that the tail light was wired the same as in the scooterhelp vma2t diagram, and was tied to position 2 on the key switch, but not tied to either of the regulators at all. I kinda figured that the tail light wire needed to be tied to position 3, 5 or 10 on the key switch. The combo of the green/white and white wires that go to the flasher unit were tied to position 3, and since I had detached all the indicators I just removed that from position 3 and swapped it with the tail light/speedo light wire that was previously tied to position 2 and... VOILA! Tail light and speedo light are now working, brighter commensurate with RPMs. The brake light gets barely brighter when I press the pedal at idle, but that’s the way it was with the battery too. I’m thinking if I swap it to the euro spec two-bulb system that may improve. The horn is intermittent but I knew that would be the case since I haven’t swapped it out. At this point I’m considering this resolved!
