What does this spark plug tester tell me?

It shows whether your spark plugs are actually firing by giving you a visible spark. You can check two plugs at once through its dual 13 mm holes. That makes it quick to spot a dead or weak plug.

Does it work on motorcycles as well as cars?

Yes, it's built to diagnose ignition problems on both cars and motorcycles running 12V systems. The two test holes are sized at 13 mm. Alligator clips connect it to your power source.

What power does it need to run?

The unit runs on DC 12V and converts 110V or 220V mains down to 12V for safe operation. It draws less than 1A. An LED confirms power, and a rotary knob adjusts spark frequency.
