Well he told me that the way some alternators are wired that it wont work because you cant change it. I take the words of you hundreds to the fact it works but is it a universal modification or is there alternators you cant do it to

big 3 is 3 "big" wires. no need for a 2nd battery, or a new alternator.

When i ground the chassis to the motor. do i find a new hole on the chasis or use the same one from the battery?

 

[jco1385 5,000+ posts]

engine to battery neg + chassis to battery neg = chassis to engine

why does no one understand that?

Was just gonna ask is that why there is 2 wires hooked up to my negative? Since ill be putting 1/0 awg whats the best way to connect it to the battery, some sort of terminal cause im also gonna need space to hook up an extra battery

you should have 3 neg wires at the battery.

1. stock wire

2. engine ground

3. chassis ground

4. IF YOU GROUNDED REAR BATTERY TO FRONT BATTERY

you should have 3 on the positive side at the battery

1. stock wire

2. alt to battery

3. run to the amp. (or rear battery)

am i missing something?

Is this after I'm done the Big3? And my grounded rear to front you mean connect them in parallel/series.

And wait, do I leave the stock cable there? I thought I need to replace them, or am I just adding on more?

 

[jco1385 5,000+ posts]

thats after battery and big 3. i'd leave the stock wire, as it may go to a fuse box somewhere. some people take them out though.

and the battery should be in parallel (+ to +, - to -)

those are the BIG 3 in green

So leave the stock negative, unless I can differentiate the one that goes to the chassis, and then all power will be new wires?

 

[jco1385 5,000+ posts]

why do you need to remove the stock wires? what terminals you got?

the list i made is very easy to understand.

 

[jco1385 5,000+ posts]

just post a pic.

that will save me ~2hrs trying to explain

Currently I have 2 cables connected to the negative and 1 to the positive, this is ALL STOCK. When I do the big 3, what do I do with the stock negative cables? Since one might go to a fuse box or something, I need to leave it connected right? I am getting a battery terminal(3 way) and with that is gonna be connected 1 wire for a 2nd battery, 1 to the chassis. My positive will have 1 for the 2nd battery, 1 running the power to the back and 1 going to the alternator.

So do I leave the stock negative cable connected?

Posting pics, btw also noticed I have 2 wires going from my positive terminal as well.

Negative

Positive

The one ontop is the power running to the d-block, but you cant see so clearly but it does split up into 2 separate cables.

-=-=--==-==

So do I replace the stock wire for the positive terminal going to the alt and leave the other wire connected?
