It depends on the voltage of the battery. Usually the internal resistance in the human body is way too high to draw any significant current from a traditional battery.
As an example, touching a 5V battery packs positive and negative poles with a finger on each hand would usually draw less than even one microampere, and wouldn't even cause a minor tingle.
It should be noted, however, that under the right circumstances a, high current, 12V battery can potentially be lethal. If you, for example, have an open wound on both hands and touch the poles of said 12V battery, it could easily cause severe burns or even death. This is because the resistance in blood is way less than that of human skin, and one would draw a much more significant current through this path of blood.
Battery is intentionally touching or striking someone against their will.
you have a short where negative is touching the metal of the car or it is grounded inproperly
Disconnect the battery cable, you do not have to touch the battery.
No, Battery is not the same as Domestic Battery. Battery is the unlawful touching or another person. Domestic Battery is the unlawful touching of a family member, spouce, boyfriend, girlfriend, room mates. Domestic means someone you're living with or related too.
Battery
A wrench touching ONLY the negative battery post/terminal will not produce a spark. For the battery to short circuit and generate a spark, something must act as a bridge between the two pots/terminals. If the wrench in question were to touch both terminals, or to touch the positive terminal and a ground (typically the chassis of the vehicle) you will see a spark because the metal body of the wrench would create a path for the electricity to travel. Intentionally creating sparks in this manner is highly UNRECOMMENDED as it will quickly drain the battery and also generate large amounts of heat. I severely burned my hand last year by touching the negative battery terminal when my starter motor died. The inside of the motor had created a short circuit which caused the rubber covering to melt off of the involved wires in just a short time. Luckily I was able to remove the terminal and end the short. The burn I sustained was small in comparison to the amount of damage the battery and vehicle could have taken from it.
non consensual touching
Yes, and so is touching it.
It comes from the plug like it cones from the battery you can say that
With an OBD2 scan tool.
you may have a dead battery of a shorted wire or component. be sure to connect positive to positive and negative to negative. disconnect one component at a time to find short. check that the exaust manifold isn't touching the starter
Get a new battery.
