For whatever reason my + terminal is tightened all the way, but it's still loose on the post... I'm going to be replacing that before too long, as it's just a disastar waiting to happen. I'll probably grab a nice beefy aftermarket terminal to really solidify that connection. It's already come loose at least once, which really had me scratching my head as to why my car wouldn't start, but, luckily I had the exact same problem with my last car and knew exactly what to check and I keep a 10mm wrench in the car to retighten if it happens away from home.
