I just did the big 3 with 4 AWG wire, since i have a GM i use side post for factory wiring, and since my yellow top has side and top, I used top for all the wires I added.

DEFINATE dimming related difference, and it looks great check out my job its on my profile link page 4 if you want. Thanks alot for thissticky it helped tons. whole thing cost about 80 bucks (battery tops were 50 for both...) and it was a well worth upgrade. Didnt take long at all either.

the 4awg was actually bigger than factory wiring, so you knooow its helpin lol How to Upgrade the Big Three - Page 4 -- posted image.

Anyone ever done this upgrade to a Chevy Lumina or any car wit a 3.1L? I plan on doin this soon but i dont know where the battery + goes to the Alternator +. Does it go through a fuse box or what? and does anyone know where the engine to ground is? I am going to use 4 guage i think because it looks bigger than stock. What do you guys think? If anyone has done this or knows where they are please let me know and show some pics if you can, please. And i also want to know if you can use both side post and top posts on a battery at the same time?

I was just going out to add to the big three, when I noticed the wire from the alternator goes to a distribution block on the firewall (90 chev pick up Ext cab.) and just a small wire from there back to the battery. My question is, can i just add a bigger gauge cable from the alt. right to the battery. Thanx

I'm having touble and am looking for an easy solution. I just put a 220 amp alt in my F250, I used 1/0 gauge wire for the charge wire so far. I plan on doing the ground this weekend. The problem is the new alternator stud is too short to use the stock and new eye terminal at the same time. I am running just the 1/0 now and I only have until mid day tomorrow to get parts in for the weekend. I have heard of stud extenders, but I don't have much clearance between the water cross over and the stock stud. What will do the trick?

Btw thanks for the walk through, I started a pdf of my process if it will help anyone let me know.

Ok I finally read this.

I always did this with highend, competition, demo and large systems. I assumed everyone knew this already but actually shouldn't be surprised.

Great info guys.

Is 2 AWG or 0AWG really necessary? I can see for really high amperage systems, but what about the guys running low amperage? My system is only like 80A. Do I need something so heavy or can I use some 4AWG like the rest of my system?

Do most people use circuit protection in the wire from the alt to bat +?.. most factory harnesses I see have circuit protection of some sort on this wire; I'm wondering if people are leaving this out when they upgrade.
