DC with 6v points stator

[jazzdude]

Does anyone know if it is possible to run a Wassell type conversion with a 6V AC points stator?

I have searched in the forums and am wondering if the same principle that makes the LGBC forum's 'easy 12v lighting' method in using a 12V regulator in a 6V AC points system, would also work using the Wassell rectifier in place of the regulator, but adding the yellow wire.

Where would you add the extra yellow?

A standard 6v AC points stator has 4 wires. 1 ignition and 3 lights.

Brown is your main lights that runs head, tail and speedo
Purple runs tail, speedo and running light (lower output than the brown) when in the running light position on the switch.
Pink, brake light.

Now in theory you could take a 3 phase wassel/podtronic type unit and run all 3 lighting feeds in to that and then take the rectified DC out to your battery and on to your lights. Will it work? It should but I can't think of anyone ever trying it.

I guess you could tie the pink and purple coils together and then run 2 phases of lights to the rectifier but that point it just gets messy and far easier to do the "easy 12v conversion".

If it were me, I'd just buy a BGM set up and call it a day.

I looked at a12v points stator that ScootRS supply and it seems to join all of the lighting coils together and only two wires come out of it, one that goes to the regulator and lights and the other to the ignition coil. It's only 40 quid.

As I am running an LIS with the thinner crank flange I don't want the hassle of going electronic with all the risk of flywheels shearing off etc. When one day I get round to doing an engine rebuild I will change the crank too and go electronic but points have served me well so far.

It would be possible, by isolating the 2 main lighting coils, but not worth doing as the power output is only just enough to run the lights. So, there wouldn't be enough to charge a battery as well.
The best way of running a points stator at 12v DC is to increase (double) the power. To do this, replace the side & brake light coils with another pair of main light coils, from another stator, and wire in parallel with the original pair.

Now in theory you could take a 3 phase wassel/podtronic type unit and run all 3 lighting feeds in to that and then take the rectified DC out to your battery and on to your lights. Will it work?

No.

I'm fine with being wrong (I'm wrong a lot) but I'd like to know why in this case.

As I understand the 6vAC stator

2 lighting coils for the brown main feed
1 coil for the purple
1 coil for the pink

I don't have a stator in front of me at the moment but I think these coils all ground to the stator and are essentially 3 outputs of AC voltage, all with different levels of power. Apart from the different levels of output (in watts) they all produce 6v AC and as I understand it should be able to be rectified in to DC with the correct 3 phase rectifier (even if it's not 12v).

Do I have the function of each coil wrong or is there something else I'm missing?
