take off negative, but when you reconnect, reconnect with the positive first. disconnecting incorrectly can cause battery explosions. or so they tell us in autoshop, maybe just to scare us.

Rule of thumb...if you not sure...don't reply to the thread.

I think that if you bridged any ground to the + terminal as you describe, you'd get a big nasty spark regardless of whether the + cable was connnected or not...

Read it again, not if the negative cable is disconnected. That's one of the reasons to disconnect the negative first!

Can't say that I'm less confused than before.
Just to be safe, I'm going to disconnect BOTH terminal.
(1) disconnect negative, push it out of the way
(2) disconnect positive, push it out of the way.
(3) cover both battery posts with the little plastic caps that came with the new battery
(4) after I'm done, connect the positive terminal back first
(5) connect the negative terminal back.
(6) done.
It can't get any safer than that, right?
