When we jump-start a car, do we connect the red clamp to the positive terminal on the bad battery (the one needs to be started) first or on the good battery (on the running car) first?
I heard lastly we should connect the black clamp not to the negative terminal on the bad battery but to somewhere under the hood for safety reasons. But where exactly? I have a picture of my Camry here with four spots marked. Which one should be it?
Check your owners manual. It will tell you which one to connect first. Also tells you which wire to remove first if you are ever replacing the battery.
Too bad I don't have it no more.
Also
battery.
Well then list the model year of your Camry. It probably has not changed over the years, but it is better to be safe. Not all cars have the same electrical grounding system.
You should not even try to jump start a newer car - if you don't fry the electronics (big bucks) the battery could explode (ouch my eyes and skin not to mention the paint!) Buy an inexpensive battery charger for $20.
Bob, I copied your picture and re-located some actual points that are solid grounds. Use these if you need to.
Someone else suggested that you should not "jump start" a car at all due to the sensitive nature of the electronics in late model cars. I don't agree with that necessarily, but HOW to do it is always arguable, so I won't actually suggest i know the proper way,as someone else invariably will argue my suggested procedure and it's just not worth the hassle.
There is a good alternative though, that involves using one car to charge the battery of another without jeopardizing either vehicle or their respective electronics.
1) disconnect the battery that's dead. No need to remove it from the car, just disconnect it.2) Using Jumper cables, connect the positive and negative cables to the "dead" battery at the posts.
3) connect the "+" cable to the running vehicle positive post.4) connect the Negative cable to a good solid ground in the running car. ( the reason to connect to something other than battery ground post/cable, is simple. You are avoiding sparks from igniting the battery gases................see?)
5) Let the running car charge the secondary connected battery for a 15 minute period or so (longer if desired or necessary), then disconnect the running vehicle and basically the rest of the connections and re-connect the battery that was originally disconnected and You should have enough to start a car with, or at least crank it to troubleshoot.Hope this helps. I was kinda tired writing this and may have missed something, but I can assure you, the general idea is in ther in it's glory.

How is a battery charger used? That would be good when I can't find another car to help me out.
Where to get one? Walmart?
It's 2000 Carmy CE.
FACT: Each year, nearly 6,000 motorists suffer serious eye injuries or even blindness because of improperly jump-starting a dead vehicle battery. All vehicle batteries contain sulfuric acid and produce hydrogen and oxygen gases. If the hydrogen gas comes into contact with a spark, the battery can explode, sending pieces of the battery and acid flying. Pieces of the battery can cut into the eye, while the sulfuric acid can severely burn the delicate eye tissue.
What happens if I connect it to spot A? Would it shock me if I touch the car or try to open the door?
Sears at the automobile section (usually where they do the tires)

Agree with that,..even with older technology, its risky to just parallel one car's electrical system across another. Alternator damage can occur once the second car starts and the 2 alternators are in parallel. I've had regulator failure occur in such a situation. The actual mechanism of failure appears to be voltage transients.
Disconnect the flat battery by removing its positive battery cable,..then connect it via the jumper leads across the good battery. The good car's charging system then sees a purely inactive load and after 5 mins will have injected enough current to restore the dead battery. Disconnect (after turning the good car off) and reconnect terminal and the car shouild start.

Bob, I saw no "point A" in any of your lables.
howevere I did lable my photo as "GroundingpointsA"
That was the name of the phot on my website, nothing more.
If you use the points (either one) that I drew large yellow arrows to, there should be no more danger to you or anything else, as long as you follow the procedure outlined in the first of the two posts I made concerning the "how to's" of Jump Starting a vehicle.
Looking at the questions posted, I do however, strongly suggest you find someone to help you if you need to do this. someone who already has an idea of how to perform the general function, and maybe let 'em read the stuff you've gatherd on this group to help minimize any liklihood of damage.
Good luck.

Sorry, man, you're going to get knocked on your butt!!!! ;)
No, man, you're whole car body is a ground! It is always connected to the electrical system, since it *is* part of the electrical system!
Oh, I meant to mention. They use these for grounding points since these are away from the battery, so if there is a spark, the battery won't blow up in your face. In the good old days of metal bumpers, we used to just touch the two cars together!
Some cars (GM, for one) *do* have separate grounds just for the purpose of connecting another battery or jump box.
Sorry. I mean point 1 as I marked. Which is the car body frame. I'm thinking if I connect the clamp to point 1, there will be electricity going through the whole car. If I try to open the door or just touch any metal surface, I can get shocked or fried, right? Didn't do well on physics back on school days. Just my imaginations.
The Two points I retouched your phots with are SOLID grounds, no paint or anything to remove. The area you labled as 1 is a body colored painted crossmember and would have to be Scraped or cleared of paint ot create a solid grounding point. Physics is nothing all that difficult, but we're talking Electricity, Not physics. If you are not a part of the circuit, you shouldn;t get any part of the current. Stated plainly - You should Not Get Shocked By the car in any way if you follow the procedure outlined. There is a possibility that you will get a static electricity shock in the cooler weather, totally unrelated to the Jump Start/Charging stuff. Once again, Good luck.

Volkswagens? VOLKSWAGENS?!?!
Well., at least they're Bugs!!! ;)
Well At least they're "antiques" ........all of the ones in my yard. Aircooled is fun. I am currently (very very slowly ) building me a street Dune Buggy with Fiberglass body.............Cheap fun!
