I was painting my engine cover and the top of the fuse box this weekend. I was looking for something else to paint. I noticed the metal bar that holds the battery in place and started to unscrew one side. That was easy enough. But trying to get the screw off of the backside was a different story. It has some kinda cap w/ a wire going through it. How do i get it off? I was afraid to force it and didn't want to break it. Any help would be great. Later guys!
