Modern Vespa

Can someone with electrical savvy take a look at this diagram and either confirm or correct my understanding of what's going on at the rectifier:

Yellow In = unregulated AC from stator
Yellow In = unregulated AC from stator
White In = ground from stator
Red Out = DC
Green/White Out = regulated AC

And what's the purpose of the Green coming off the upper fuse? Isn't it redundant? Looks like it supplies DC to the ignition switch, which Red also supplies.

Thanks.

I'm pretty sure the green/white out is DC as it feeds the horn and rear brake light. The other green (also dc)is a fused link for the head and tail light as 3 feeds 8 (Head light) and 2 (tail light) in key position #2.

Thanks Tierney.

The reason I'm asking is because I'll be ditching the battery on the scoot I'm building, and using a BGM regulator that gives you the option of converting AC from the stator to either regulated AC or DC depending how its wired. Which should it be?

I went with a Trail tech 12 volt AC regulator because the turn signals were roached and I never use the horn anyway ( you lose both in this process) As I understand it, Vespa had to deal with the DOT standards of the time and the easy way out was to convert everything to DC to run the lights, turn signals, horn, etc... Problem is, the stator can,t really keep up if you are using a lot of power, especially if your battery is a little wonky. Anywho, Easy way to do this: 1) ground one of the yellow wires to the frame, 2) Connect the other yellow wire to the in feed reg, 3) connect the out feed from the reg to the red and green wires (10 & 3), 4) float the white wire or ground it out. Now this way converts it to 12 volt AC regulator. If you want to stay 6 volt, I'm sure there is a way, I just don't know how you go about it. If you have not bought the BMG one yet and you want to go 12v AC, I have another Trail Tech in the box that would be yours for the asking.
I liked this set up on my 74 Super, never blew a bulb, headlight was bright and one less thing to check on the scoot.

That's awesome T, thanks. I have the BGM 6v regulator, which is supposed to work pretty well. Let me see how it does ... if I need the 12v Trail Tech, I'll give you a shout.
