How do you test a glow plug

Model: (Various brands) Various
Part: Glow plugs

In this video, the youtuber teaches us a way to test a glow plug, which is nothing more than a resistor; the terminal part becomes incandescent, in order to heat the air inside the combustion chamber. To test it, you only need a multimeter, which we will set to "ohm" mode. We put the negative probe on the ground, and the positive one on the part we want to test. If the glow plug doesn't work, the result will be an infinite resistance, equal to zero, because it is burned inside and no longer has the ability to heat the probe, so it will give you an error on the instrument panel, because it no longer has a ground. This operation can also be done with the glow plug mounted: we take the ground from the engine, and the positive probe on the glow plug. If the result is zero, then the glow plug is burned and needs to be replaced.
