Can you touch a spark plug wire?

As long as the spark plugs and wires are good not a problem for the wires to touch. They don’t fire at the same time and the distance between wires is always more than the spark plug gap.

What precautions need to be followed while replacing the spark plugs?

To avoid plug damage, always use a six-point socket. Never install a spark plug that has been dropped. To change polarity and equalize the firing wear, rotate spark plugs between even- and odd-numbered cylinders, or as specified by the engine manufacturer.

Can you get electric shock from car engine?

This type of malfunction often leads to an engine that doesn’t run well, as the wire shorts out and delivers its charge straight to the ground rather than to its spark plug. If you insert yourself into the equation, you’re likely to get shocked.

How many volts does a car Spark Plug have?

Spark plugs usually require voltage of 12,000–25,000 volts or more to “fire” properly, although it can go up to 45,000 volts. They supply higher current during the discharge process, resulting in a hotter and longer-duration spark.

Do you need to disconnect battery to change spark plugs?

No. The battery will not cause any problems when changing the plugs. The one thing to avoid is accidentally dropping a tool and having it contact the positive battery terminal and the car body. If this occurs, you will get a spark and possibly blow a fuse.
