Here's my method and theory. Positive first. If you happen to ground the edge of the wrench to frame tightening the postive. No arching or sparks. Put negative on last and ensure you have wrench such that it cannot touch positive post or clamp. Has worked for me on everything I own with a batteries. Also beware of your fingers with any metal rings. Wedding bands school ring etc. Will arch, spark and conduct
