Now that you have tried in real life you start to find out that the wonderful thing produced by experts doesn't save you any money over building something yourself.
The ultimate thing that determines what you get from a wind turbine is the size of the blades, the wind speed and how well the parts are matched.
You give no information on anything except the useless voltage figures you first quoted.
At best you are playing with something similar to the AirX and it will take a lot of wind to do much. Car alternators are intended to be compact and produce power cheaply at high speed. You eventually have to accept that to get reasonable power from wind you need large blades and a slow and costly alternator or a speed increasing transmission.
Wind generators also needs very high efficiencies in the lowest winds, where power is strictly limited anyway.If you take something designed to produce about 500W with modest efficiency at 5000 rpm you mustn't expect much from it at speeds that a wind turbine are capable of.
Car alternators and small scrap dc motors are being advertised everywhere as the basis of decent wind turbines, in reality they are toys if you want something useful.

Don't take all my criticism too seriously as it was aimed at the first person and he may still be very happy.
The basic comments about the futility of car alternators still apply and they will only produce worthwhile outputs on very high wind sites. They may work well enough on the best inland sites and may supply the modest needs of a boat at sea in a real good wind area.
You are diverting from the thread but I will say this:
He took issue with my attempt to help, called us snobs and requested I not comment in his Diary and I should remove it. Also claimed he did not want comments. By removing the comment of mine it removed the replies. Per his request.
No need to comment because I already know you will automatically take the opposite view and it would simply further divert the thread.
Damned if I do and damned if I don't.
Thanks for your concern.
Tom.
