The negative is exposed and seems easy, but doesn't the positive really drive everything? If so, do I remove the negative and then "pop" off the two places the arrows point to and then unscrew it to remove the big positive terminal plate on top? I've never seen anything other than a simple terminal connector on a car (like the negative is).
