Is it really as easy as this article wants to make true?

Or would you need to do anything to the stator?

My TV is 6V, points, battery model. Reason for upgrade is to be able to run a SIP speedo as well as charge satnav etc...

Many thanks, Victor

Yes, this does work, however, you do not end up with a great Wattage output. You do end up with a steady 12V output but you only have a limited power pool to use so you quickly find that using things together causes a shortage of power, e.g. put your foot on the brake when the lights are on and the headlight output drops... to the point that it looks as though you are flashing your lights, which may put you at risk of vehicles pulling across your path! The same goes for using the horn when the lights are on.

Fitting an LED rear light bulb (many places sell 12v LED rear bulbs and these work well... some are far cheaper than others, even though quality is the same!) helps greatly as it takes less power from the other lights when you put your foot on the brake. This really is a must!

You can rewire the stator for higher Amp output but it is pretty involved, to the point that this is no longer an easy (or cheap) 12V conversion.

I rate this conversion but first step should be having your flywheel remagnetized by AFR or one of the other dealers that has the correct tool (me when Lee sells me one... no, not you Cookie!!!!), as poor 6V is often down to poor flywheel charge... this would still be poor for the 12V conversion unless remagnetized. I do use the reworked stator option of this conversion on 2 of my own scooters.

Thanks Adam. The problem is not poor output from the stator but I need to be able to run the SIP digital speedo, thus need to go 6V -> 12V. An added benefit is that I'll be able to charge the iphone which wont consume any power really. Besides that, there is nothing else drawing power so I'll make sure to get the led rear light bulb and keep my fingers crossed.

Second stage would be to upgrade crank and stator, but want to limit expenses and work at the moment getting the bike on the road asap

Brake light runs off the battery if i'm not remembering wrong, buheadlight runs off the ac normally, doesnt it? Is the outcome of this conversion that the 2 6V outputs (charging and lights) ends up as input to the regulator, and you then split the output back to the light and to the new 12V battery?

Cheers Victor

Going beyond my understanding of running twin feeds, however, I can confirm that a standard 6V powers the lights AC. There are various versions of the Vespa regulator conversion, however, I can't advise you on the DC version.
