If i took a car's alternator and bolted the fan to it stuck it in the wind could I charge a bank of batts. If so, could whoever knows how, send me a wiring diagram. how many rpm's does an alt. need to start charging anyway?

You certainly can. The newer alternators have an integral regulator which controls the output to 13.8-14.2 volts. This would be ideal if all you want to do is charge batteries or power 12 volt devices.
The older alternators have an external regulator, and without the regulator controlling the stator voltage, they will output around 90 volts at 1800-2000 rpms!
The voltage is DC in both cases because of the internal rectifiers. These can be bypassed if you require AC voltage.

Yes as all the car does is turn the pully attached to the alternator, which in turn produces electricity. All the fan blades do is cool the alternator as friction produces heat. To answer your question your alternator needs as much rvm on the firnt fans as it would on the rear. You would never get the speed you need to produce electricity by installing it outside of the car wwithout applying pullies to increase speed which would not be beneficial to you.
You can buy systems already to install on your car to give you electricity.(110 volts ac ect.).
If you want to charge a bank of batteris(I am asummingyou mean an electric golf cart or car.
You can do this several ways and you would need detailed information and the money and equipment ot put it into actual use.
1- you can attach (1 to 4) generating devices ot the weels of your car. or to the rear axle )cut into the axle a pully to attach the generator. every time you drive the car the pully will turn the generator, and this will keep the car batteries charged.
It makes sense also that if you can charge a car or golf cart with a commopn 15 amp 115 volt outlet and you can attach a divice to your car giving you the same 115volt/15 amp it will work .
Look into autos and information on such things there is a ton of ionformation on the internet

Yes, you can generate electric power by spinning the shaft of an alternator. That's what it does indside the car!
You could connect the alternator's input shaft to the output shaft of a windmill and make electric power when the wind blows. The exact circuitry needed to do this would depend on the make of the alternator and on the type of power you wanted (AC or DC, what voltage, etc.). You would probably want to have the alternator feed power into a battery to store up power for when the wind was not blowing. Since the electrical system of cars is 12 Volts DC, and you probably want 120 Volts AC for household appliances, you would need to use power conditioning equipment like that used by home solar electric systems. Check out a book called the Whole Earth Catalog for info on home power and alternate energy systems.

you can do it it an old alternator not the modern ones though. why I do not know ?

Why would you want to do it that way? You can't come up with anything more economical? i.e. less resistance?
