Topic: Dual Battery Question..

[844x4]

First let me say I have tried reading evey tpoic I can find about dual batteries. 
I think I know what I want to do now, but I'm not sure which wire is the alternator output that I would hook up to the battery isolator.  Its a carbed 84 with a stock alt set up that is externally regulated. 
Help?

dont run a battery isolator, they rob power..... use the kit from www.12voltguy.com

Do you use the kit?  What does it include?
I am runing a warn m8000 and have a pretty little battery right now about 525cca I think.
I am wanting to add a deep cycle for my winch and leave the other batt for starting etc.

its very simple,  run  the  deep cycle to the winch,  charge  the  deepcycle  with a wire  to the alt,  use a  ford starter solenoid to isolate it when the switch is off
simple as that

Ok sounds good, now back to my original question.  On the stock alternator, where do I hook up the wire?  I know there is a wiring harness that plugs into the regulator but I fail to see a nice fat wire to tap into, or is there another terminal on the alt I can use?

theres a 10mm nut on the alt  that the main  wire goes under, the rest of the wires  are  regulator/stimulator/charge light

Thats what I needed.  Thanks.

Strange I run a couple of them in my mh with no problems.

simple as that

I do this in my mh but only to link my batteries together when I need that extra juice to fire that beast when the engine is hot, but for charging I let the isolator do its job.
