Alternator Wiring Upgrade

[Mick]

Hey i want to upgrade the alternator wires to thicker gauge wire and i was wondering what other people have done with there wiring, the reason i ask is that the white power wire from the alternator to the fuse box has a big crimped and soldered terminal on the fusebox side which has a very thick black starter motor wire and the white alternator wire together in that terminal and it is angled to fit perfectly so im not sure how to remove the white wire and add a nice new 8 or 4 gauge alternator wire to it, im also not sure what gauge to use cos i read that 8 will to upto 100amp but i thought of using 4 gauge cos i got a few 4 gauge terminals and wire laying around but im worried that its too big so what ate your thoughts on what gauge wire to use and on how to connect it to the fusebox side?

i will include a photo of the terminal im talking about and yes i will also do the earth wire as well thats an easy job

The good news is that change is dead easy. Just use a second terminal on the same stud (or the other one, they are connected by a metal bar) for the new wiring. Cut the old wiring as close to the terminal as possible and wrap well with tape

what gauge wire would you use, its only a short distance from the alternator to the fuse/relay box
