Brah, you can keep making any assumptions you want, there's a reason that every single veteran on this board recommends the big 3. The less resistance you have in your electrical system, the more power your going to get out of it, period. If $10 for a piece of wire is too expensive for you then by all means skip it, but in a world where people drop hundreds (thousands) of dollars on equipment, cheaping out on the electrical side is how things get blown.

also if your going to start something like this dont delete your pics from your pic hoster

this. plus all my wire was free

bunch of whiners in this place now

[d2k]

instead of running out 0AWG onto TB3, could i just leave the existing 4AWG runs & then add 3 runs of 8AWG onto the connections..??, so 1x 4AWG & 1x 8AWG per connection..??


im thinking the difference between changing the 4AWG for 0AWG will be pretty much the same as what i described above..?? no..??

What is TB3?

I already said to leave the stock wires if you can and just add on, but I definitely wouldn't add 3 runs of 8 AWG that's just dumb, do 1 run of 1/0 and be done with it, then you don't ever have to worry about upgrading it again (unless you go huge in the future)

right...... cheers!!

Do the ground wires need to be less then 3ft like with ground wires from an amp? I cant really find any engine block bolts within 3ft of a chassis ground.

No, it's just generally a good idea to keep them as short as possible. The point of grounding the engine block is to ground the alternator chassis so if you can easily use one of the alternator bolts, go for it.

[jco1385]

and your engine block is setting ON the friggin chassis. if you can't find a bolt within 3ft, you got a huge ass engine and or car.

So if I'm gonna do my pos alternator wire, and I have an external regulator, I need to somehow go through it? Never done an ext. reg. before

Or, a heat shield is in the way, and Id rather not melt wires by taking the shortest route.

true. btw i got your pm about the wire i have FS i still have it....

[Johnsonmn2]

I know this is probably in this thread 90 pages ago but when doing the big 3 do you have to do the wires to the fuse box also? Or could I just skip the alt to fusebox, and go straight to the battery with an added inline fuse?
