Big 3 using postive jumper terminal

[ace_800]

So my Enclave's battery is behind the passenger seat not in the engine bay, but there is a positive jumper there. I figure that it is always connected to the postive of the battery wo would there be an issue running a 2ga from the alt to the jumper?

I dont see how it could hurt

well, that's only half of the issue. the wire gauge of the factory wire from that post to the battery is also important if you're adding a system. you want to size that post-batt wire for whatever you want for power wire/draw. likely it's not much larger than 4awg.

i'd upgrade the wire from the post to the battery with 1/0 if you want to make a difference.
