I won't even attempt to try to give you a correct/incorrect answer, I went through this wiring up my vbb with a 12 v dc . I basicly just did what I was told
Take a look and see if this helps wiring help needed

Meaning?? If you indeed used this regulator, you should know that it will be emptying your battery, cause on your circuit it acts as lets say a "coil" that will be constantly drawing power from it...

The fact that it's a 5 pin regulator doesn't mean it's the proper one for your scooter. The letters are different for a reason. These two regulators work differently...

PX wiring looms came in many variations and cause of that there were two different 5 pin regulators. You have the wrong one for your PX / wiring loom / circuit. Again, the letters on the terminals are there for a reason. The double "A" regulator on your PX will be emptying your battery overnight...

Safis is so right about draining your battery and vice versa. The newer PX regulator will drain a battery in an older P200E, too. I know cuz I had a new PX regulator on my P200 and the battery just drained. All other lights worked fine. You definitely have a older P200E regulator. I think you can make it work by changing the stator wiring or running without a battery but not worth the time.

Send me a PM and I'll send you my newer PX150 regulator with double G's for postage. It's from the east (Middle East or Far East) so quality maybe questionable but if it works, great.

And the wires are wrongly connected, even on your old regulator. You have mixed up the wires between the regulator and the flasher. Maybe that was your problem all along??

G: Green / Yellow

Good catch Safis. Based on his 1st pic the blue wire and green wire should be switched.

Try changing those blue and green wires in the old regulator and see what happens. Your problem maybe solved. Regardless, that new reg you got won't work and no one has the correct wiring substitution for the different letters. But if you want, go ahead and install it with a charged battery. Time will tell you if that regulator would work.

Not only those. He has also mixed up the flasher wires with the regulator's and I bet that's the reason he gets no charging. Pay attention to the +B & C terminals. He has the Red / Black & White wires that should be on the flasher and the Red & White / Red that should be on the regulator are on the flasher...

My previous post with the diagram tells the correct order...

I'll work on the wiring tomorrow. So far, no issues with the electric start. Horn is a little weaker.

Thanks

Well, I switched the blue and green/yellow wires and reused the old regulator. Guess what, it works!!!!!

Now, I switched the wires on the flasher and regulator as mentioned above, and it blows the fuse. WHY????

Yeah, scratch that. Apparently the US model PX has the wires connected differently. So, apart from the first two wires you already switched, the others were OK. I donít understand why they did this change when Piaggioís wire coloring is pretty much the same even on their latest models...
