So I've been working on cars (bolt ons, mainly) for nearly a decade now, and whenver it comes to disconnecting batteries, I simply remove the wire and when ready, reattach it...I don't use any safety equipment, and it often occurs to me that I'm messing with something potentially dangerous, and that maybe I should be more careful...

so, how do you all disconnect your batteries??

 

Pull the negative wire off the battery, you're good to go. Always the negative and if you pull both off, hook up the positive BEFORE you connect the negative.

 

Here is some info from Google:http://www.popularmechanics.com/auto...o/4213127.html

That has not changed over the years.

 

I had a guy that worked for me that called in one Monday morning that he had injured himself working on his car over the weekend and was going to take the day off.

When he came in the next day I saw his arm and it looked like his hand was just about amputated at the wrist!!!

The battery was hooked up and he got his metal watch band between the positive battery terminal and some metal part of the car and burned an imprint of the watch about 1/4 inch deep into his wrist. He was lucky he didn't have any nerve or muscle damage, but it took months for it to heal up and he still had a scar that looks like a watch.

So.....like StoplightWarrior says, a good idea is to take the negative terminal loose and secure it away from the battery post.

With all the electronic stuff on the C6, about the only thing that you need to do when you hook the battery back up is to index the windows. All the computers seem to pretty well remember everything else, and I recall.

Another thing you might notice is that the DIC might not display the tire pressures properly until you drive the car faster than 20 mph for a couple minutes, then the TPMS will pick up the transmissions from the sensors and all will be well.

Neg. (-) Terminal is removed first. To keep the arching to a minimum try to keep the wire in contact with batteries terminal while loosening the bolt. Once the neg. cable is off I usually wrap a towel around the cable end to prevent accidental grounding.

In my teens I worked at a car audio shop and have been "bitten" by regular 12volts a few times...only once by a large capacitor. Battery 12volts isn't that bad but those capacitors can light you up pretty good. I remember a loud pop, bright sparks and the wrench I was using went flying across the shop.

My dd is a Toyota Prius(yahhh I know:o ) and you have to have special gloves, tools, etc. to work on the Hi-voltage/current battery packs...one hit from a hybrids pack can be fatal. They have all the hi current stuff wrapped in blaze orange as a warning.

 

thanks for the tips, guys!

 

Many years ago, I was disconnecting the battery on my 1969 Camaro and the wrench touched the fender brace. BANG. The battery exploded and threw acid all over me and the car. I did not know at the time, I should have disconnected the NEGATIVE first.

 

Negative should be the first one off, and the last one on.
