charge trek XIV - can i make it bigger?

[tim eh?]

so the new alternator is much better, but it hasn't fixed my charging problem.

this probably won't go in right away but here is the cable that i am planning to use to replace what's there.
the large grey to battery+, the small grey to the starter , and the green to alternator b+.

the grey cables are 4AWG, same as i have already.

i think the old altb+ wire is 8AWG and i have 6AWG.... is that bad?
bigger is better right?

That's fine... bigger is always better.
