I have an 86'LT250 that I want to putt some mods on that require a 12 Volt battery, and power when the engine is not running. How can I set it up so that I charge the battery from the stator? Is this a possibilty? I don't know exactly how many amps will be drawn from the battery at full load. So I don't know what amperage that I need from the battery, so I don't know how much should come from the stator to charge.

Full Version: Charging A Battery
I think that I have figured this out, but I would like some advise from the experts, to make sure that I am correct, and if they see any other problems.
The LT250 Stator pack has three different coils. (see picture #1) One of the coils is for the ignition and goes directly to the CDI which controls the spark at the spark plug. The other two coils are for the lighting circuit, and somehow are wired directly to the lights for those night time rides.
I plan on leaving the ignition coil alone. I don't want to mess that up.
What I will do is rewire everything from the ligthing coils back. I will add a rectifier circuit, and a voltage regulator that will prevent over charging the battery. (check out pictures #2 & #3) A battery, that will go to a fused distribution block for all the assesories.
Now I need to know what bike uses a setup similar to this so that I can use it rectifier/regulator pack. I guess there needs to be two channels for the rectifier.
Didn't Suzuki make an electric start model quad in the 200cc-350cc range once?

Back in school. 
Don't forget you are going to need an AC to DC converter. If a bike doesn't have a battery it puts out AC voltage. You will fry your battery if not converted before the power gets to the battery. Try seeing if the new Suzuki 400 quads will help you wire it up.
OK. THIS IS BECOMING TECHINICAL AND WAY OVER MY HEAD. AS I ASKED BEFORE, WHERE ARE ALL THE ELECTRICAL ENGINEERS WHEN YOU NEED THEM?
The following is the results of hours on the web...and not working like I should be.
To convert the A/C power to D/C I can bridge a series of diodes in a bridge configuration.
If I use a Zener diode this will regulate the current to the battery.
I think that I have it figured out in theory, but now I need to calculate the actual values of each of these components.
I will keep you posted....If you have any advice let me know.
