Now you can go out to your vehicle and cycle the ignition switch to the “on” position and in a period of three to five seconds, you can start your engine. The glow plug used now can reach 1,000 degrees F in that short time.
Turn off the engine and remove the glow plugs from the engine block. Connect the multimeter’s red probe to the terminal on the glow plug’s tip and the black probe to the engine block or some other ground. Set the multimeter to Ohms and check the resistance. The range for most multimeters will be 0.2 to 2 ohms.
As most cars have four-cylinder engines, that means four glow plugs. If one glow plug fails, the engine may still start but it might run roughly initially. That’s because it will take a bit of time for the cylinder without the functioning glow plug to get up to temperature and work properly.
