Modern Vespa

Hello I would like to run the new variable from SIP but am not sure if I need the dc version or the ac version?
The instructions for the ignition dont seem to address this US scoot with battery.

Looking at the wiring diagram for this bike it seems the only thing running ac is the headlight.

I converted my Stella over to all DC with the new SIP ignition. It was a trivial change and allowed me to go all LED.

If you're not wanting to do a full DC conversion, though, you probably want to A/C version, which should plug in fairly seamlessly to the existing electrical system.

It looked like the bike is already wired dc aside for the head light.

But if ac is the easier thats fine i just dont know where to put the wires. I have the sip wire diagram amd the diagram for the scooter added.
I have the wire diagram for this bike and the wire diagram

Well, would you rather have a battery and a full DC system so that you can charge electronic devices (phone/GPS/ect...) and utilize LED or HID lights, or a full AC system (in which you can't charge those items or use those lights)?

and let me help Chandlerman help Chandlerman by linking Chandlerman's thread... SIP Electronic Ignition Install + DC Conversion

LOL!

I started to share my own link at work, but then got distracted by a squirrel or something and forgot to hit Submit or something.

But, yeah, I've already Been There, Done That with the SIP Ignition DC conversion and am pretty damn pleased with it thus far.

Thank you for the wiring diagram. Im printing it out so i can look at it better than with my phone.

Its hard for me to tell what was changed as i dont know what the wiring diagram looked before the changes. Was there wiring changed anywhere besides at the stator/rectifier?

At this point im just looking for any info as my wiring is different from anything else i can find. If you look at my wiring diagram the only thing thats ac is the headlight.
The rest goes through a factory rectifier which converts it to dc. So im thinking the dc one is the easiest path for this bike.
The ac wiring would be easy if my wiring matched the instructions or the sip video it does not.
I could be weong but to use the ac one i would have to convert my wiring to ac?

That was the same as my bike. The headlight was the only AC circuit, but the stock stator delivered AC to a regulator/rectifier.

The stock R/R went in a drawer and everything bonded together, eventually on a relay through the key, when I went full DC & LED. Plus, I get the headlight even without the motor!

Does anyone else have any input or wiring diagram for wiring any variable ignition into this scooter?
I cant find anything.

This two yellow wire setup seems to be different from most.

are you sure it's the original/stock wiring harness?

Yes. Its the first wiring diagram here. https://www.scooterhelp.com/electrics/pages/VNX1T.p125x.html

lets say I get the DC version.
I replace my rectifier with theirs.

I have 2 yellows that will be gone and replaced with the new blue and black wire coming off the sip stator

The green wire will go to the blue with white stripe on sip coil for kill switch.

From the chassis wiring im left with.

a violet (that appears to supply unregulated ac voltage to the headlight.) i need to know where to put this wire.

A black wire. Looks like a ground. Maybe i ground it to the black wire coming off the sip recrifier? I need to know where this wire would go as well.

The ground wire goes to the frame. I just bolted mine to the frame with the same bolt I used to attach the regulator. That's the way my old R/R was installed, too.

The violet headlight wire can either be bonded to the output from the regulator--that's what I did in my initial install--or you can install a relay and run all the power through that and let the key power the relay on/off.

That will reduce the length of the wiring run by basically 2/3: instead of Does that help?

It looks like that purple wire from your stator (that goes to the headlight) will now need to be connected to your battery (the RED 13.8VDC power appliance wire).

The black wire is a ground. It looks like you can attach it directly to the frame or to the new SIP rectifier.

I believe you'll also need a new turn signal flasher relay. I think yours is AC, you'll need a DC.

Your two yellow stator wires won't be used at all.

That long single green wire (ignition kill wire) that goes back to the Ducatic coil, will now plug into the blue/white wire that's coming from the new SIP coil.

To be clear the violet wire will attach to tge red 13.8dc wire coming out of the rectifier?

Will the headlight bulb work with the dc current or do I need a different bulb?

Are you talking about the indicator flasher i have circled in attached pic?
I may be wrong but I thought all those dotted lines were dc current powered off the ignition switch? And the purple in the center is coming out of the rectifier.
Am I wrong?

The dotted line is the white wire.

Hey Rowdy, just to clear it up for Radioflyer, some i'm going to expand on that just a smidge...

A dotted green is a green wire with a white stripe (or visa-versa). Dotted red is a red wire with a white stripe (or visa-versa).

Thank you that makes sense.

I figured the indicator flasher was dc because it ties in with the horn which is labeled dc.

I dont want to burn the thing up. Ha

It's been many years since I've had working turn signals in my P that I forget if they were AC or DC. Before I give out too much misinformation, you can easily test to see if yours are AC or DC. With just your key on (bike not running) will your turn signals flash? If so, then the flasher unit is set up for DC.

Your turn signals should be DC.
