Default 2008 Big three upgrade

Hello I'm looking to do the big three upgrade and I've seen some forums for special charging for the battery where as the power wire from the alternator runs through the fuse block and then to the battery, if I directly remove this wire and fuse a 250amp alternator with a 250 amp fuse to my battery will my car still function properly, the alternator is internal regulating, along with upgraded 0 gauge grounds all around.

You can... It's basically electrically the same. The real question is, wth are you powering that requires you to need a 250 amp alt?!?! I have a 180 amp alt with an xs power battery and that's more than enough to handle my 2300 watt system...

2850rms system and some powerful lights, my car also has all the heated seats an defrosters. Just to be on the safe side and ensure no voltage drop once the bass hits

Alternator to battery.
Battery to chassis.
Engine block to chassis.

what i did was use the bolt that holds the alternator on the right side and ground directly from that. I saw a .4v increase just from that alone.

http://www.paranoidfabrications.com/...grounding-kit/

same principle no matter what the car. tying the primary part to the uni-body on the ground side.

On the Big-three you are improving flow from the alt to the battery through the ground circuit. the Ground kit is critical for a big three to give you the most it can. Regardless of alt size.

.4v+ just doing ground kit. do the big three, especially on like a 2.5i or moderate car, where the car manufacturer further skimps on electrical costs can see upwards of a full volt at idle.

its a system and everyone forgets power in our 12v-ground vehicles flows from GROUND TO the 12+ battery terminal. It flows backwards to conventional thinking.

Good terminals (NOT GOLD!) proper termination (crimp and solder), and cleaning the metal will yeild best results.

Should I use both stock writing and 0 gauge on the battery terminals? Also there is a wire coming off the starter to the positive battery post

many piggy back the Alt wire, I think its ugly and not necessary, unbolt, tape off both ends and tuck it away.

Starter wire you won't get it out. So just undo it, tape tuck and route the new wire safely away from heat and sharp/moving objects.

Usually you have t upgrade the bat terminals anyway to either a multi-lug or a multiple hole car-audio style terminal to accommodate 0ga-4ga even some 8ga.

www.darvex.com or bag-boy on ebay. Same person. His name is Trail and will create packages and save shipping. He is in Arkansas, soi its pretty central to all states.

And no I don't work for him. He has helped me build my last 5 projects though.
