Yeah I do plan on going with the larger gauge but I'm not sure where I need to put this larger gauge, also not sure what to do with the fusible link. It's hard to say what the fusible link is for, either to prevent overcharging from the alternator or to prevent the vehicle from drawing too much from the battery (the way it's wired seems weird to me). If the link is more for the alternator then it would seem that I should replace it with the big fuse. But if it's more for the vehicle drawing too much power from the battery then me putting a huge fuse on there might allow for other issues??
