And more importantly, do you have jumper cables? If not, at least buy them even if you don't know how to use them.


I was in Iowa this weekend and had a rental car, so I didn't have cables. My battery died, which put me in quite the fix. The hotel didn't have cables I could use, so I had to ask other people as they were leaving the lobby. Took me 18 people (seriously, I started counting after the fifth and counted couples/groups as '1') to find someone with cables (or someone who would claim they have cables).

Then a tad bit of embarrassment because I couldn't remember the order to put the cables on to jump the car. Luckily the other guy did. Don't have to jump a car too often and 'don't use it, lose it' applies to this as well evidently.



And to those who know better than I about cars: I've always been told to put the ground cable onto a metal part of the car. However, the guy who helped me out insisted it goes on to the negative pole of the car battery. I went "ya know, I don't think that's right" but since I was the guy who forgot the order any how, I didn't press the issue too much.

I went online to print out the order so I don't forget it again and wind up with someone else who forgot/doesn't know, and they're all backing me up with putting it on metal. So which way is it? Or does it even matter? My dad told me it can blow the battery but my car seemed to start up fine. Might've just been lucky though.

It doesn't matter if you put the negative on the post or the metal body.

You can cause serious problems if you accidentally switch the positive/negative though, and you get an awesome spark show if you try to put the positive on first without grounding. Crossing the cables can (so I am told) make the battery explode in some cases, fry the battery/alternator/wiring harness/etc. and also weld the cables to the posts.

Maybe the grounding on metal rule is extra insurance against accidentally putting it on the wrong post? That would make sense, since the consequences of crossing cables is so bad.

I don't have jumper cables and have no clue how to jump a car. Luckily, the one time my car died right outside of my work's parking lot, my boss came out and did it.

No, I don't know which goes on which side. I'd just rather not mess with it. I do have an emergency kit in the trunk with cables, though, and have always found someone who would help do it when I've needed it. I've only had to do it once with this car anyway and it didn't even work, as I ended up needing a new battery. Luckily, I was in the Wal-Mart parking lot, called my friend Josh to come help me, and we went in to buy a new one for him to put in.

I always put the black cable on neg..... And it's always worked. And yes, I keep jumpers in the car... Although, i still haven't switched them into my new car. Maybe I'll go do that right now. Lol.

Yes I have them and have used them numerous times to jump other people. Owned a lot of hoopties over the years and just got into the habit.

It doesn't matter if the black goes on the positive or the negative, as long as you're consistent (i.e., black on negative on the jumping car, goes on the negative or metal frame on the jumped car).

The bit of reading I did on it says you can put the negative on the negative post of the dead car battery but it did say it's better to go to something else metal in case there's a crack in the car battery. By completing the circuit on the dead car battery, you run the risk of explosion if the dead battery is cracked or faulty.

This is just what I gleaned from an on-line article (which I was reading on Sunday because my Father's truck needs to be jumped sometime in the near future as it's taking up room in my driveway).

^what they said.........you were both right GO, BUT, sometimes it's easier to get the negative to clip and STAY on to the metal frame of the car! If it 'pops' off the negative post during the charge, I was taught that is NOT a good thing, LOL

I can't believe that many people in a snowy area didn't have cables :eek: WOW!

Have you ever seen/tried this type of jumper? Pretty cool! And you don't risk that "SPARK" when hooking them up, or having them hooked WRONG and frying a cars electrical system LOL

i used to have cables in my car untill the ex took them and never gave them back and now "cant find them" and i cant afford a new set right now...

i was always taught, negative to negative, that may be because alot of tha cars in the UK are plastic composit and dont ground well, then again that also goes for alot of american models too, and theres not much "think metal peices" in most engine blocks lol.

im always extra diligent about making sure the cables are on properly and safely...

those safety ones however look cool!!!

my dad has a jumper in his car, which when i finally have money im thinking about getting one for mine, least you dont have to wait for soemone else...
unfortunatly around here, even if you HAVE your own cables, youll be lucky to find someone willing to stop and jump you...*sigh*

Yes for both. I also have free roadside assistance through my car insurance, so they'll come jump it if necessary (or if I'm driving a rental car and don't have cables). I guess it's not free...I pay $5/month for it, but I've used it several times, so it's paid for itself!

I have jumped many a car in the past. My old roommate was notorious for leaving her lights on and needing a jump. I actually was just thinking recently that my jumper cables seem to have gotten up and walked away. I need to buy some new ones.

Depends on the car. On the little 318i (because it's old enough not to have all of the sensitive computer chips and hyper-sensitive electronics, yes, I know how to jump it. On the 750il? NOTHING gets hooked to the battery. The only way that battery will get recharged is to disconnect it from the car, and there is no way in Hell I will jump another car off of it.

If you've got a newer car with computerized running gear, it's not smart to use regular jumper cables.

They also sell jumper cables that are attached to a battery... so you can jump your own car... this is probably the best to have because you dont need any help from others.
