How To Do The Big 3: Tutorial

it is the same wire. they arent different, you are just adding more.

visualize it like this. you have a cup of water and a coffee straw. you just ran and are thirsty. you try to drink the water but you can only get so much at a time because the straw is so thin. so lets say you get another straw (like the one they use for boba drinks) and use it as well. so try to drink again with the coffee straw and the boba straw. you can get satisfied faster and more efficiently than with just the coffee straw.

hope that helps. thats how i usually explain it to my friends who ask me how it works :)

edit: and to answer your second ques big mike, it doesnt have negative effects. you are helping your batt and alt.

Will this BIG 3 process have an negative effect on the charging system or the battery at all?

no. it will help the car on the voltage issues. actually it helps the charging system also

I have an 03 Dodge Dakota.

My pos. to my alternator comes from the fuse panel

next to my battery. The fuse panel has about 6 inch pos.

wire to the battery that connects to the same pos. post

as the alternator pos. inside fuse panel. The alternator pos.

wire has a fusable link that I plan on replacing with an inline

fuse. Question is Would it be better to run alternator pos.

straight to battery or to run it back to the post inside fuse

panel? Don't know if it makes sense hope so.

leave your old wireing alone..

you ADD a wire pos alt to pos bat( in line fused)

you ADD a wire neg bat to ground(somewhere on your frame, somewhere that is a ground)

then you ADD a wire from engine Block to ground(somewhere on your frame, somewhere that is a ground)

you skip over all the fuse boxes thats already there..all you do is add the wire new to those places...

so for the engine block to ground, I just find a bolt on the engine block and connect it to a ground of some sort? That is the only part of this whole thing that is a little bit confusing.

bolt on engine block > battery negative ?????????

Instructions dont really make sense, but you have a positive going from the altenator to the batterie, then you have a ground going from the engine block to a grounding spot, then a ground from the negative side of the batterie to the grounding spot? Is this right?

What do you think? Any revisions needed before going public?

Did you do your big 3 over your factory wiring, or did you remove the factory wiring and replace the 8g wiring with 1/0g?
