When chasing down a no crank no start issue on my 07 JKU (turned out to be bad negative wire attaching to the battery, which upon fixing fixed the issue), I also discovered a weak ground post which broke off (photo attached.) The ground wire and terminal are good, but I can't reattach it to that post now. Can I use a self-tapping screw to screw it onto the frame right next to the post? Should I use a washer in between the terminal connector and the body? Is there a better way to do this?
