Airbags in dash?

Disconnect the negative terminal of the battery.

Disconnect both battery cables!

Why both? Won't disconnecting the negative post on the battery do it?

Doh! (embarrassed grin) Thanks!

Yes, but I like to be "VERY SAFE" and removing both removes any chance of having electrons flowing.

I like to go one step further. I strip down to my skivvies, rub my body with non-fat yogurt, and remove BOTH battery cables while balancing on one foot and singing "I Am Woman". Sure, the neighbors look at me funny, but one can never be too safe.

I understand, and it certainly can't hurt to use a little extra caution.

Plus you probably have a lot of other people in your vicinity when you work that could throw a wrench (figurative or literal) in the works.

Okay folks, enough grab ass here. Before everyone falls over themselves agreeing with Woodchuck's recommendation to remove BOTH battery cables (I suspect he was being a bit sarcastic to stress his point), someone needs to give me a REALISTIC scenario illustrating how NOT removing the positive cable can lead to an unfortunate battery mishap. My assumption, of course, is that the negative cable is properly removed, covered and/or secured so it cannot spring back and make contact or arc while you are working. Again, REALISTIC is the key word here. Don't give me some wild-ass scenario that has a zero percent chance of ever happening. Any takers?

Electrical tape over the empty post would add security. Let's not assume that happened.

Aluminum foil sandwich wrapper blows onto battery and bridges negative post to chassis.

Wife sets pan down there when you ask for another flashlight while under dash.

Not zero chance. Much better chance than winning the lottery, however.
