Should a spark plug wire shock you?
In theory, it should not shock you through the boot. However, it is possible for the spark to jump out around the boot and shock you that way. If the wires or boots are cracked or brittle, they should be replaced. If you’re having a problem with missing or inconsistent running, plug wires are often the problem.
Can you get shocked by spark plug?
You can only get a shock from a spark plug if the engine is running. And if the engine is running you should use some sort of gloves, and take extra care about what you are doing. There are quite a few things that can go “wrong” if you decide to work on a running engine.
Why did my car spark when I touched the spark plug?
Why were you shocked? The spark-plug wire you touched contained an insulation fault — perhaps a small split or crack in the rubber coating. The wire might have been routed such that enough distance (air) prevented a spark from leaking to ground, causing an engine misfire.
Why are spark plug wires can zap you?
Why car’s spark-plug wires can zap you. Depending on the ignition-system type, typical voltage at steady speed will range between 5,000 to 10,000 volts and jump to perhaps 15,000 during acceleration. Higher voltage is usually the result of a faulty spark-plug wire.
What causes a spark plug to catch on fire?
The spark-plug wire you touched contained an insulation fault — perhaps a small split or crack in the rubber coating. The wire might have been routed such that enough distance (air) prevented a spark from leaking to ground, causing an engine misfire.
What’s the average voltage of a spark plug?
Depending on the ignition-system type, typical voltage at steady speed will range between 5,000 to 10,000 volts and jump to perhaps 15,000 during acceleration. Higher voltage is usually the result of a faulty spark-plug wire.
What should I do if my spark plug wire is bad?
With the engine running, move the test light along the length of each spark plug wire. If a spark jumps from a plug wire to the test light at any point, this is an indication that the insulation has broken down, and the spark plug wire should be replaced.

What happens when a spark plug gets cut?
Abrasion damage – When spark plug wires rub against engine parts, particularly sharp edges, it causes cuts and breaks in the insulation. Once this happens, voltage can jump to ground instead of reaching the spark plug. Use the digital multimeter, set to Ohms Ω.
