DC conversion - not floating ground

Edit: I have loaded this on dropbox. It should work. I've a bunch of people ask to see it so I thought maybe this would be easier. I am not claiming it's perfect or the greatest thing ever. But if it can help anybody I am happy to share it.

Thanks. It's been a year and the bike is still working great. I did ruin that battery because I let it go completely dead over winter and it wouldn't charge back up but that was my fault haha.

I lost a battery the same way this past winter. It was on the old lady's honda reflex and I just forgot about it, lol, oh well no big deal.

I don't have a white wire coming out of the stator on my 2005 EC 250. Do I need to rewind the stator to be able to wire in a DC reg/rectifier? I have the yellow, green, red, red/white, and black/red wires coming from my stator. It has a small 12v AC regulator mounted near the ignition coil as well. It is an American market bike as far as I can tell.

Just curious, is it still possible to use the red/yellow wire for delayed shut off with this setup?

ive put an e start on my old gasgas. How do avoid a frame earth when the starter motor is bolted to the engine. That is the earth!

I just need a small charging circuit, not bothered about lights ect

help??, still not having any joy

As you have noticed, the starter motor uses a frame ground. Since you have an aftermarket FULLWAVE rectifier, you need to float the ground at the stator. This means that the stator frame ground has to be removed from the stator plate and connected to a new wire. So the rectifier input gets powered by the white wire and your new wire. This isolates the stator.

The rectifier output goes to the battery positive and battery negative. Battery negative is connected to frame ground so the starter motor functions. Keep in mind that your battery positive wiring to your switch gear should be fused for safety. Connect everything to DC so it is easier to understand the wiring.

For adding estart you should only need a simple hookup like this diagram:

I have attemped the original method that is in this thread but I am having an issue. THe power fluctuates horribly to the battery...fluttering lights, etc...Anyone else experience this?
