I bought a mean green alternator it says to output 300% more but they don't tell you the amps. I plan on replacing and i m also putting in a die hard platinum battery which has the concepts of a optima battery. They say to just pop it in and not replace any wiring but i don't believe thats what i should do. I want to run a good 4g wire to the alt. heres a picture below that shows my diagram sorry it looks like a grade schooler made it haha. It seems the power goes to the fusebox then to the alternator also 2 small gauge wires goto the plug on the alternator which are small grounds I'm guessing they 0 out on my dmm. Theres no power going from battery straight to the alternator. Any advice on wiring up this mess?

if you are refering to the big 3 you have two combos on the i did the first because geeting to the engine blocks ground is a pain and also remeber to fuse within 18 inches of the battery. the big3 must be the same guage as your amps power wire or your wasting your time
alt ground to car ground
alt postive to battery(fuse)
Battery negitive to cars ground
or
engine block to cars ground
alt postive to battery (fuse)
