you will require to run a 24v to 12v transformer (converter) you can not hav bateries hooked up in series and still run 12v of one of them.

Why run 24v?

I think you can have 12V.
If the batteries are connected in series, then the juction between the batteries (+ve to -ve) will be at 12V potential WRT to earth.
There is also 12V potential between the junction and the +24V.

However this defeats the purpose of having 24V, as only 1 battery would be used to supply 12V.

So it's a waste.
Just get a good 12V alternator and a good second 12V battery (with good battery mangament), and a good 12V winch.

the problem is that we wanna 24v the winch so it will go really really fast
but still run the car

and it's gonna be a pain in the ass to run two altanators with everything else that's there on the 383 chev there's not much room left in the bay anymore

Don't try getting 12V off one of the batteries used for the 24v. Doing that causes charging problems and eventually you'll stuff one or both of them.

something sorta off topic:

with 2 x 12V batteries in a 24V system, if I were to wire up spot lights, where do I get the 24V power from?

do I have the positive on battery (1) with all accessories and negative on ground/chassis which battery (2) is grounded to?

robbie, do you mean how to connect 2 batteries to make 24v?

(bat 1) + [positive for 24v supply]

(bat1) - connected to (bat2) + [common point only]

(bat2) - [negative for 24v supply)

nar, its already in 24V.. what I am trying to ask is whats the best way to wire up spot lights?

+ to Battery 1 positive & - Battery 2 negative?
