4. The dual-hole automotive spark plug tester has two test holes, which can test two spark plugs at the same time. If you suspect that any spark plug is not working properly, you can do a comparative test to make an accurate judgment
5. Test principle: In the automotive ignition system, the high-voltage ignition coil generates a high voltage (more than 10,000 volts), and the spark plug leads it to form a high-voltage ignition coil into the cylinder engine. The spark between the spark plug electrodes ignites the mixture. The detector can distinguish good spark plugs from bad spark plugs according to the intensity of the spark
6. Turn the key switch clockwise to turn on the tester, and the indicator light is green

Interesting book, dull period
Format: Paperback
As a Marxist historian, Hobsbawm sees the world at this time, as well as the modern world, as a playground for the forces of capitalism. He apologizes for taking a eurocentric approach to world history, while acknowledging that Europe largely determined the course of world events during this period. In spite of the title, there actually isn't much discussion of colonial empires; Hobsbawm seems more interested in how the Age of Empire affected the rulers more than the ruled. His Marxist sympathies are in evidence and at times make his conclusions a bit predictable, but some of his cultural critiques are quite brilliant. The chapter on the dilemmas posed by modern science is exceptional. Reading a book like this seems to me much more interesting than actually living in this period would have been.
