Replying to: imidazol97 (Oct 27, 2009 4:31 pm) Can we just say one thing and get it on the table? KEEP JUMPER CABLES AWAY FROM ANY MODERN CAR!! Only in the most dire of emergencies would I recommend this anymore. And if you HAVE to do this, make sure the donor car's negative cable is the last to be attached, to a frame member.

Replying to: Mr_Shiftright (Oct 27, 2009 5:00 pm) Regarding the dead battery car, I understand the Neg cable should be attached to a metal part, other than the Neg post of the dead battery. I forget why the donor's Neg can't be attached to the Neg post of the donor battery. Appreciate your reply.

Replying to: euphonium (Oct 28, 2009 8:00 am) Both for fire hazard and current surge. I'm hearing more and more about damage to modern cars done simply by jump starting---even jump-starting correctly. I suspect in a few more years this procedure will be forbidden or severely discouraged by automakers. Not sure what that means for AAA, but oh well. I understand there are "intelligent" battery cables out there, but I don't know much about them at this point. Perhaps this is the way AAA and car owners will cope with this issue in the future.
#4939 of 4944 jumping by stickguy Oct 28, 2009 (8:19 am)
one thing I have burned into my memory (that I will remember long after alzhiemers makes me forget my name) is how to jump start an Opel Manta. starting with the "good" car, it was pos-pos, neg-ground (grounding on the Opel hood hinge) are you saying now it should be pos-pos, ground-ground? Or ground on the good car, then neg on the dead one?
#4940 of 4944 AAA by stickguy Oct 28, 2009 (8:22 am)
they don't use cables anymore. They all carry those portable battery boxes. IIRC, one cable to the battery, and I guess a ground? Unless that is built in. If you can't jump, are you supposed to replace the battery any time it goes dead? That seems ridiculous. All batteries should come with that little hidden reserve that one model has 9something where you turn a switch, and it uses the "hidden" juice to start the car) Replies to this message: Mr_Shiftright (Oct 28, 2009 8:25 am) oregonboy (Oct 28, 2009 5:03 pm) Mr_Shiftright (Oct 28, 2009 5:20 pm)

Replying to: stickguy (Oct 28, 2009 8:22 am) yes I've seen those "batteries within batteries". Seems like a good idea. Also those portable battery packs seem safer, since they aren't hooked up to another car's alternator that's pumping out extra juice. That's what I use. I threw away my jumper cables. The reason I suggest that the last cable to be attached is the donor car's negative frame side, is that the jumper (meaning me) can control the entire situation, and is also away from either battery in case of explosion. You don't want to be near an exploding battery---this is a very nasty business. Replies to this message: oregonboy (Oct 28, 2009 5:03 pm) Mr_Shiftright (Oct 28, 2009 5:20 pm)

Replying to: Mr_Shiftright (Oct 28, 2009 8:25 am) The danger is the spark that occurs when the final connection is made. Batteries can accumulate hydrogen gas. A spark occurring near the battery (like at the negative post), can ignite the hydrogen and make the battery go BOOM.... or so I've heard.

Replying to: oregonboy (Oct 28, 2009 5:03 pm) I've seen it happen...eye-witness. It's nasty. Think of it as an acid-filled hand grenade made especially for you.

Replying to: euphonium (Oct 28, 2009 8:00 am) You want the last connection to made far away from a battery, so that any sparks do not set off any hydrogen gas that may have out gassed from the battery,
