Guys to go full DC lights and Battery you wire the stator as above. If you want to charge a battery and keep the rest AC you can use the Vespa 5 pin regulator or the small BGM one that trickle charges the battery and keeps your light standard.
The BGM ones work very well but it's debatable if you are getting a full wave DC cycle more likely to be half wave so it's charging rate is not as good as a Wassel and the extra wire. I have recently removed the guts of a standard 6 v regulator and hidden a BGM 6v inside for a mate who wanted the Original look.

I dont know the first thing about wiring a stator plate.As far as I know (which isn't very far when it comes to wiring)you can buy a DC stator plate that you connect to a 5 pin regulator and this way you can run and charge a battery,or you can buy an AC stator plate that you connect to a 3 pin regulator if you dont run a battery.

The stator plate itself is identical you just wire it different depending on what you're connecting it to. It always produces AC it's what you connect it to that makes the whole set up AC or DC.

The three pin is a regulator. AC

The five pin is a combined regulator / rectifier with trickle feed. AC main DC to battery

The Wassell unit is a full rectifier. DC all round.

The Wassell stator conversion with two yellows can be either AC or DC. For AC you connect one yellow to earth and one to the regulator for DC you connect both yellows yo the rectifier.

Why,o why does everyone make it so complicated.Even in the back of "Stickys"manual it has all the wiring diagrams and it says DC- with battery,AC- no battery.

The problem is over the years things changed at the factory. The U.K. Wanted battery's as I understand we were supposed to have parking lights. Italy didn't need them. The rear brake light used to reduce the power available at the headlight so it dimmed when you brake. So they decided on some models to use the battery for the brake light. O yes and the horn on a Vespa works while the one on a Lambretta just quacks. Don't get me going on AC and DC wireing looms or AC DC ignition switches. They have subtle differences but you don't have to start again just coz you want to add a battery.
In your case look at the model you have find the drawing in Stickys that the closest to yours and work from that. If it's only a battery you want it's easy.
Stator stays the same. Swap the regulator from a 3 pin to a 5 pin or BGM. Add the extra wire from the regulator to the positive on the battery with another from negative to ground via a fuse. Then you decide what you are going to wire off the battery like spots phone charger etc. It's still the same as Stickys AC but with a battery.
