So I have a broken clamp on my positive terminal box that’s keeping my car from receiving efficient charge (Car cuts off while stopped). So I removed the battery to get easier access to all the plugs you see in the picture. I’m having trouble unplugging these plugs even the screws holding the 250Amp and 350Amp cords are a struggle getting loose and ultimately off. Feels like I may break the terminal all together, which I am trying to avoid, but can’t seem to figure out how to remove these cords. If there’s anyone out there that has any advice on how to resolve my issue or any warnings of removing these cords please let me know. Thank you and hope to get some help.
