How much amperage? Mainly it’s the charge wire from the alternator to the battery that you need to upgrade to carry the juice. 75 amp? I’d use 8 gauge. 100-120 amp? 6 gauge. More than that 4 gauge. Use quality wire, a lot of stuff I see anymore is aluminum that is copper coated, that won’t carry as much current. I know some will say bigger gauge but it’s such a short run those sizes in a quality wire will carry the current. When you get at the hundred range you’ll want a fuse (mega type) for protection.
As for charging issues, do you have a lot of accessories added? Maybe just the components you have could use a refresh or replacement.
