Skipping Isolator

[jeffm4688]

So with the second battery I'm putting in my trunk I should just run my now power wire to the positive on my alt and use the run going to my trunk? & no big 3 would be needed then correct?

As of right now my 1/0 is attached right to the post on my fuse box where the alt drops power off to. Can I keep it like that and just connect to my rear battery cause how I see it its the same thing. Fused on both sides of course

Your best path to do this is to simply do a Big 3 (1/0 engine ground, 1/0 to your main battery, and 1/0 from your main battery ground to chassis)

And then to run a 1/0 from the main battery positive to your rear battery positive.

The whole point of a Big 3 is to in theory get maximum output from your alternator by increasing the wire size (causing less resistance)

I plan on doing a big 3 in the upcoming week or two.

But ok it looks like that's what I'm going to do I already have a 0 gauge run going to the rear.
