For safety purposes always always remove the negative side first. This eliminates the possibility of shorting out your wrench against the body or any other negative charged part. There is strong possibility of shorting out the battery which could blow up. This happened to my brother as a kid and he ended up with battery acid in his eyes.
Try unhooking the negative side of the battery as this may reset any relays.
