Big three

[khaled_94]

Hey all

need help from an expert to teach me how to do the big three mod for my 05 denali LQ9 6.0 ​

Big 3 isn't difficult...

1- Alternator to Battery +. (I fuse mine according to my current needs)
2- Battery - to engine gound. (I connect mine to one of the Alt mounting bolts)
3- Battery - to chassis ground.

Not the greatest example- but this is the big 3 in my Suzuki. for a visual reference.


Hoping to be doing my Avy Soon- but it will be much more involved, as I'll be running dual Batteries.

Cuz I am overly cautious. Cheap insurance being that I have a 160 amp Alt. JUST incase I ever had a short betwen the alt and battery.
