I am interested in contacting some people who are running a Jacobs
wind generator. I am talking about one of the old models. I have a
model 60, 40 Volts, 70 Amps. It is called a "long case". Right now I
need some help with a wiring diagram. I need to know more about a
diode and controller. I have a 5000 Watt square wave inverter and
four L16 batteries. I will use this inverter for now until I am sure
that everything is working all right and then I want to eventually
connect to the grid with a sine wave inverter.
I know that there were some postings on this subject a few years ago.

I have the very same one running here.

1950s technology, you don't need it ;-).
My system currently (pardon the pun) uses a simple rectifier in the
disconnect box and then directly charges my battery bank. Two Enermax
charge controllers divert any excess to hot water heater elements.
Not bad, but the further plan is to replace the rectifier with an
OutBack MX-60 instead, and see what that does. Theoretically, it
should help the startup of the turbine, and reduce the rectifier
losses. There's more on all that on the OutBack forums.

I'd suggest that your battery bank is rather undersized for a wind
turbine of that size if you have a good location. That's what,
probably ~500 at 24 if you're planning on using the Jake for charging?
Thats what, 250 usable at 24? The problem with a turbine of this size
is that if the wind really gets going, and it starts throwing fifty or
sixty amps at near 40V into the batteries, they can't "suck it up"
fast enough in a small bank like that, and if they did, they'd be
overflowing/boiling in a matter of hours. You'll want to include some
very good diversion capability.

If you do that, I do recommend the grid tie inverters from OutBack.

GEEEZZZZ. Check out the input max input voltage on the MX-60. The last
one discussed was 55vac max input.
My open circuited 1kW wind turbine put out 200vac before I chickened
out (it wasn't intentional) and got the shorts back on it. Would have
cleaned a MX-60 right our of your wallet. The turbine is a 48 vdc
battery bank system and designed for it.

Where was that discussed?
I've not seen any specs for maximum AC voltage input for the MX60

Oh, there are voltage maxes. In a PV system, it's usually 72v
Nominal ;-).
