A 12 volt battery, no matter how large, cannot electrocute a person. Not enough voltage to even feel a shock through your hands, It takes about 30 volts to start feeling a shock.
As for the ignition wiring, that is high voltage of 20000 voltas or so.. It`ll give a short low amperage jolt. Not pleasant but not dangerous.
Shorting a 12 V car battery can easily melt or burn the wiring involved if there is fuse protection in that path.
@ErateGamer Yea even about 1 Amp is almost guaranteed to be fatal to a person, but the point is a car will never send 1 Amp through you. A car can't come even close.
This all started about the car's ability to shock you after all.
@ErateGamer a car is 12V, maybe 14V from the alternator - it will never shock you badly enough to hurt you. A Car's headlights typically draw 12 Amps, but if you touch the circuit you get a few milliamps at most because the human body has a higher resistance and the voltage is only 12 Volts. As for tasers they have current regulation to prevent the normal current values predicted by Ohm's law when given Voltage & Resistance.
@ErateGamer The current will not go through your body if there is not enough voltage. The resistance of the human body varies. According to wikipedia it can be up to 100,000 Ohms, but if you are wet or have broken skin, as low as 1,000 Ohms, and during severe electrocution the skin breaks down and the resistance can be only 500 Ohms. Even in the 500 Ohms scenario, the current draw from touching both terminals of a 12V car battery is 24mA. This is a *jolt* but 100mA is the minimum for "danger".
Don't turn on the working car if you are going to try to start the dead car.
Two reasons.
One: having the working car charging does not help (look at the tiny thin size of the alternator wires compared to the thick big size of the starter motor wires)
Two: You may damage the working cars voltage regulation or other related electronics. (this damage may become evident only in a few weeks or months).
Hey i have a question, for the dead car you place the negative end to the frame. Whys that? is it bad to place the negative end cable to the negative battery of the dead car?
It will work, but its dangerous. You're essentially grounding the circuit by connecting to the frame or negative terminal. Both ways sometimes emit sparks, which is dangerous near a battery because it can cause an explosion, and thats why you connect to the frame... away from the battery.
good job man! next one you should tap the + and - connected to the dead car to show people how much current is going through the circuit once the cables are hooked up to the good battery and how much it will mess them up if they shock themselves :P
are those ontario plates i see? of course they are, because we are the only retarded place in the world that requires plates on the front of the car!
if you're stuck nowhere, you can always push-start your car. You set your key to ON, set your gearbox in 2nd gear or reverse while holding the clutch, you have someone push the car (from rear or front, depending your gear choice), then suddenly release the clutch once the car gained some speed (doesn't take much). Once it started, leave it run for a few minutes (at least 10-15) to let the car battery get a basic charge.
If there's no one at all to help, it's still possible to do it by yourself if there's a small hill or if you can manage a way to hold the clutch down with your leg (or an object) while pushing.
everyone knows that its so easy ! tell us how to fix a dead car battery not how to charge it !!!

Correction:
Shorting a 12 V car battery can easily melt or burn the wiring involved if there is NO fuse protection in that path.

You cannot get a shock from one car battery.
Don't turn on the working car if you are going to try to start the dead car.
Two reasons.
One: having the working car charging does not help (look at the tiny thin size of the alternator wires compared to the thick big size of the starter motor wires)
Two: You may damage the working cars voltage regulation or other related electronics. (this damage may become evident only in a few weeks or months).

Isnt it only 12V? maybe 14 from the Alternator... you cant get shocked bad.
