Re: alt to bat (pdd000)
You simply run power wire from positive battery post...(see image below).
Then you run that wire to your alt...(see image below).
Don't forget to fuse about half way with an ANL fuse rated at the alt output...(see image below).
Also ground from negative battery post to chassis and from engine block to chassis. Make sure your ground wire is at least the same size or larger than your power wire.
I used pics of my C4 Big-3 wires since I don't yet have pics of the C5's. Hope this helps. :seeya

Re: alt to bat (pdd000)
Don't mess with the stock electrical system wires. Just add all new wiring to it. No smaller than 4-gauge. If you look at my pictures above you will see where the wires run to, it's the same on a C4 as it is on a C5. Just in the C5 the battery is on the passenger side of the car making it a longer run to the alt. You can ground anywhere on the frame you want, you don't have to jack the car up or anything. The shorter the ground runs the better.

Re: alt to bat (pdd000)
ok guys. i got the alt fuse block and fuse rated at 140 amps for the new alt. im gonna run 4gauge from the alt to the batt so i fuse this half way to the batt and not right nere the batt? im gonna run 0/1 gauge from the battery to the rear of the car to the distrabution block. also ill run a new grd from batt to frame with the 0/1 gauge. also when i run the grounds from the amps can i run the grd amp to amp then to a grding point instead of running all single grds to 1 point?

Re: alt to bat (Metal_Wulf)
:nono: don't run 4ga from your alt to the batt... use 1/0ga like you're doing for everything else
I actually still have the same wire left which is the same lenght as I used in my vert with 2 connetion rings.
Let me know if you wanna buy them !!!

Running 4-gauge wire between alt and battery will actually be ok since you are running 1/0-gauge for ground from battery to frame, just don't forget to also run a ground wire from frame to engine block too. Others will say to run the larger wire between alt and battery which is good too, that just gives you even more headroom, and that's always a good thing. Remember, you will also have your stock wiring in place too. :yesnod:
im gonna run 0/1 gauge from the battery to the rear of the car to the distrabution block.
also ill run a new grd from batt to frame with the 0/1 gauge.
